The train driver in the courtyard

The stuck drill incident at well No. 1-13 on the fourth road alarmed the entire well site.

There were hundreds of workers on site, and the consequences would be unimaginable if the drilling rig collapsed.

Everyone present was stunned. It wasn't until Li Aiguo walked over that Ma Lanhua came to her senses.

"Driver Li"

"Get everyone off the derrick first!" Li Aiguo interrupted Ma Lanhua. Although the derrick had stopped swaying, it might have been damaged and could collapse at any moment.

Ma Lanhua realized what was happening and directed the workers on the derrick to come down.

The first to be evacuated were a few drillers and Master Chen, the chief driller.

Malanhua knew the accident was caused by a stuck drill and called Master Chen over.

"Old Chen, what exactly happened?"

“It’s possible,” Master Chen hesitated for a moment before saying, “It’s possible that I gave the order too softly and Wang Kun didn’t hear it clearly, which led to the drilling being started ahead of schedule. I’m also partly responsible.”

Even Malanhua, the team leader, was confused, since she wasn't on the derrick.

At this moment, Wang Kun also climbed down from the derrick.

The moment his foot touched the ground, he shouted at the driller, "Old Chen, your skills are terrible! You don't even know when to start drilling. How can you demand to start drilling as soon as the drill string is stuck? If I hadn't hesitated, the drill rig might have collapsed already."

Li Aiguo thought to himself, "Wow!"

They made a mistake and caused this mess, and now they're trying to shift the blame.

Master Chen never expected that when he tried to help Wang Kun, Wang Kun would push all the blame onto him.

He wanted to explain, but as an honest and simple driller, he was not good with words and could not explain clearly at all.

“Master Chen, you’re getting old, you shouldn’t work on the front lines anymore. It would be so much better if you went home and held your grandchildren. This time, it’s all thanks to my quick reaction.”

Seeing this, Wang Kun became even more smug: "Captain Ma, Old Chen has caused a huge disaster this time. I suggest he be suspended from his duties immediately, and I will take over as the head driller."

"boom!"

Before he could finish speaking, a foot flew out from the side and kicked Wang Kun directly.

The kick was so powerful that Wang Kun was sent flying like a sack, landing on the ground and kicking up a cloud of yellow dust.

Wang Kun VS Dadi.

Earth wins!
The intense pain caused Wang Kun to cough uncontrollably, and it took him a full half minute to recover.

He looked up and saw that annoying figure.

"Li Aiguo, what are you doing!" Wang Kun struggled to stand up.

The person who assaulted him was Li Aiguo.

"You're quite clever to shift the blame onto someone else!" Li Aiguo wasn't interested in getting involved in the internal affairs of the Fifth Squad, but he couldn't just stand by and watch an old worker be wronged.

"Whoever is shirking responsibility is Master Chen who made a mistake."

Wang Kun's eyes flashed with panic as he shouted to the drilling workers beside him, "Old Liu, Old Zhou, I've been beaten by outsiders, aren't you going to help me?"

The workers exchanged glances, but none of them showed any intention of stepping forward.

They know Wang Kun too well.

However, because they were teammates and there was no evidence, they did not step forward to help Master Chen.

Seeing Wang Kun get beaten up now makes me feel really happy!
Wang Kun was furious: "Fine, you all keep saying we're a collective, brothers. Now that your brothers are in trouble, you're all cowering like turtles."

"Li Aiguo, how dare you hit me! I'm not letting this go!"

This was the first time Wang Kun had ever been beaten, and beaten so badly at that. He was so upset that he stood there making a scene like a woman.

Li Aiguo crossed his arms and just watched him quietly.

"Enough!" Zhang Shanlin, the captain of the 3012 drilling team, rushed over after receiving the news. When he saw this scene, his face immediately darkened.

"Captain, I didn't cause the accident." When Wang Kun saw the captain arrive, he quickly ran over and pointed at Li Aiguo to complain, "This guy hit someone."

"Wang Kun, the matter hasn't been investigated yet, please calm down."

Mr. Chen's eyes reddened with anxiety; if the blame fell on him, he would be fired.

Wang Kun felt reassured and continued to repeat his accusations against Master Chen.

He spoke with great conviction, portraying himself as a victim.

A lie repeated a thousand times may become the truth.

When there were a few employees who had a good relationship with Wang Kun, their attitudes changed somewhat.

The captain was having a bit of a headache.

There were many people on the drilling rig at the time, but they were all quite far apart. Coupled with the roar of the machines, everyone was focused on their work, and there were no witnesses at all.

It is impossible to confirm what exactly the driller Chen's orders were at the time.

The two sides are now giving conflicting accounts, making it unclear who should bear the responsibility.

At this moment, Li Aiguo spoke up: "Captain, may I ask the two of them a few questions?"

"Of course." The captain had a very good impression of the train driver who had saved the entire drilling team.

When the drilling team workers saw that Li Aiguo wanted to ask them questions, they all gathered around.

Li Aiguo walked up to Wang Kun and asked with a smile, "Wang Kun, according to you, you felt that the order from the chief driller was inappropriate, which is why you hesitated for a moment, right?"

Is that all?

Wang Kun was initially a little worried, but upon hearing this, he immediately straightened up: "That's right, it's thanks to my hesitation."

Li Aiguo then asked, "Why are you hesitating?"

Wang Kun replied, "Of course, it's because we're about to get the drill bit stuck."

The words had barely left his mouth when Wang Kun realized he had spoken and quickly shut his mouth, but it was too late.

Li Aiguo smiled at him, then said to the captain, "I've finished questioning. Now I can confirm that Wang Kun was the one who caused the accident. Wang Kun is lying."

The onlookers began to whisper among themselves.

"What's going on? How did you come to that conclusion?"

"Are you stupid? Just because the drill rod hits the saltwater layer doesn't mean it will get stuck. There must have been a wellbore collapse at that time."

The lead driller could detect this using the instruments, but Wang Kun, as the assistant driller, whose job was simply to control the drill bit, how did he know in advance?

"Oh, I see. I didn't expect the train driver to know this."

“Wang Kun is really a scoundrel. Master Chen is protecting him, but he tries to frame him.”

The captain was also shocked by Wang Kun's shamelessness and said in a deep voice, "Wang Kun, you are suspended from your duties immediately. I will report this matter to the headquarters!" "Captain, I didn't do it on purpose. I was just scared." Wang Kun was also flustered at this moment.

"No need to say it!"

The captain had several team members take Wang Kun back to the shack, and then walked up to Li Aiguo.

"Thank you so much, patriotic comrade." He said this from the bottom of his heart.

If Master Chen was truly wronged, he would never be able to forgive himself for the rest of his life.

"You're too kind. We're all comrades. The most important thing now is to repair the derrick as soon as possible and continue the work."

Li Aiguo's words woke up the team leader. Now that an accident had occurred, it would definitely affect the subsequent drilling work.

We must race against time to get the stuck drill bit out and repair the well wall.

The brigade leader reported the accident to the State Farm General Farm, which sent a rescue team to help, and Section Chief Xu also came along.

The staff at the main site tried conventional methods such as "soaking in oil to remove the card" and "using a shocker to remove the card", but all of them failed.

However, due to severe damage to the well wall, the drill bit was firmly stuck in the rock crevice. If it were pulled out rashly, losing a drill bit would be a minor issue; the entire oil well would be destroyed, and the original drilling site would have to be abandoned.

The important thing now is not the drill bit, nor the oil well, but the drilling point.

In later generations, if an accident occurs while drilling a well, the construction company will pay a high price to hire a water ghost to retrieve the drill bit, which is the same principle.

The important thing is not the drill bit, nor the well, but that the well must be drilled in the original location.

However, this oil well is seven or eight hundred meters deep, and no water monster can go down into it.

Finally, Li Aiguo came up with an idea: "Since we can't get the drill bit out from the front, what about from the side?"

Section Chief Xu was smoking when he looked up and asked in confusion, "The side?"

Li Aiguo picked up a wooden stick and drew a few lines on the ground: "Look, the well diameter of this section has now increased by more than 40%, and the collapsed rock blocks are blocking the annulus. The original wellbore no longer has the conditions for conventional unblocking and repair."

Section Chief Xu and the technicians nodded.

Li Aiguo continued, "Since we can't remove the drill bit, let's just not try. We can use the stable strata above the collapsed section as a build-up point and drill in the direction of the directional drilling at a certain build-up rate. As long as the horizontal displacement is controlled, we can ensure that the new wellbore accurately penetrates the original target layer."

Upon hearing this, the scene fell silent; even the experienced craftsmen had never heard of such a method.

Section Chief Xu instinctively wanted to object, but after thinking it over carefully, he realized that it was feasible.

"Go and invite Chief Engineer Wan over; he's an expert in this field."

Like Professor Hua, Chief Engineer Wan is a returned expert and one of the leading petroleum experts in China.

Unlike typical experts, their work focuses on oil wells and drilling.

At this time, Chief Engineer Wan was at the No. 2 well site discussing the next drilling plan with the captain of Drilling Team 1205.

Upon seeing the messenger who came to deliver the message, Chief Engineer Wan was somewhat puzzled: "Isn't there a fixed procedure for handling stuck drills? Can't Section Chief Xu handle it himself?"

"Chief Engineer Wan, because this drilling accident is quite serious, a comrade from the railway has come up with a new method. Section Chief Xu is hesitant to approve it, so please go and take a look," the correspondent replied.

Upon hearing this, Chief Engineer Wan looked at the team leader and said, "Old Wang, you've been working continuously for more than half a year now, you should also take a break."

"Only those who are useless to the people and society get to rest," the captain, covered in oil stains, waved his hand.

If someone else had said this, Chief Engineer Wan might have thought they were just being pretentious, but this person was different.

Chief Engineer Wan understood his temperament and didn't try to persuade him further. He turned around and got into the jeep.

Watching the jeep leave, the captain surnamed Wang scratched his head and said, "The railway department people have all come here to do their work, so we have to work overtime."

When Chief Engineer Wan arrived at the No. 5 well site, he could see a group of people gathered in a circle under the derrick from a distance.

When Section Chief Xu saw Chief Engineer Wan coming over, he stood up and explained the situation. Then, pointing to Li Aiguo, he said, "This is Comrade Li Aiguo from the Qianmen Locomotive Depot. He just proposed the method of diagonal drilling."

Chief Engineer Wan quickly got to work.

"Quick, bring the blueprints over."

Section Chief Xu didn't even bother to return to his shack; he had a technician bring over the technical drawings for the oil well.

Chief Engineer Wan took out a pen and calculated on the blueprints for a while.

The more he calculated, the more excited Chief Engineer Wan became. When the last number was calculated, he suddenly looked up.

"Comrade Patriot, you're a genius!"

Seeing Chief Engineer Wan's expression, the leader in charge of handling the accident pressed him for an answer: "Chief Engineer Wan, is this method feasible?"

"It's not just feasible, it's practically perfect!" Chief Engineer Wan's voice trembled with excitement.

Pointing to the blueprints, he said, "Following Comrade Aiguo's method, we can bypass the collapsed area and use a combination of 'secondary casing + tailpipe' to penetrate the original target oil layer. This not only preserves the drilling site but also saves a lot of manpower and resources."

Chief Engineer Wan is a technical expert, and his words carry authority.

Section Chief Xu immediately looked at Li Aiguo: "Comrade Aiguo, how exactly should we dig this inclined shaft?"

Li Aiguo didn't refuse to help, explaining all the technical details he could think of.

"The key to construction is safe re-drilling. The original wellbore needs to be sealed by injecting 425 grade cement into the stuck section, along with sawdust, to ensure that the original wellbore is completely isolated from the new wellbore."

"We also need to precisely control the wellbore trajectory."

"."

Sidetracking technology was originally created by petroleum experts to solve stuck drill accidents, and it has become quite sophisticated in later generations.

As he listened, Section Chief Xu picked up his notebook and took notes.

"I feel this is a complete technology."

After hearing this, Chief Engineer Wan became even more excited.

If this side-drilling technique is feasible, we won't have to go through so much trouble in the future when encountering stuck drill accidents.

"Comrade Aiguo, since you came up with this side-drilling technology, according to the practice in Daqing, it should be called Li Aiguo Side-Drilling."

Li Aiguo's side-drilling technique. Well, it sounds better than "side-leaking."

Li Aiguo's lips twitched twice: "It is indeed a good name."

The work pace in Daqing is even faster than that at the Qianmen Locomotive Depot.

In the afternoon, Chief Engineer Wan and Section Chief Xu reported their plan to use Li Aiguo's side-drilling to resolve the stuck drill incident.

The leaders of the main farm convened experts to discuss the matter, and the experts unanimously agreed that the technology was feasible.

As evening approached, the headquarters officially approved the plan and also dispatched two drilling teams to assist.
