1988: Back to the human world for a few years

Chapter 13 Please be a human being!

In fact, from the perspective of future generations, the truly technical aspect of oil drilling lies in the early coordinated design work, including geological exploration and analysis.

Once the drilling operation begins, unless there are previously unexpected complex geological conditions or rare complex accidents, under normal circumstances, accidents such as drill sticking, especially shallow drill sticking, although it seems to have a great impact and is also time-consuming, it is really not a helpless problem from a technical point of view.

In the words of later generations, the various methods used to deal with common drilling accidents in the 1970s and 1980s were actually like application problems of the four arithmetic operations. Although they looked dazzling, in terms of the basic logical framework, they were not closely related to the word "profound".

Take the drill bit for example.

Before the millennium, oil companies only drilled and mined large and medium-sized, shallow and medium-layer oil layers with relatively ideal geological conditions. Therefore, the causes of drill bit jams in the North China Plain are nothing more than the following:

1. Drill stuck due to well wall collapse;
2. Sand settling type drill stuck - drill stuck due to insufficient mud viscosity;
3. Drill bit jamming caused by human accidents - the highest proportion of drill bit jamming and drill bit piercing is caused by dropped objects.

As a reborn person, Yang Mo had been a victim of writing thousands of reports for other departments in his previous life. Among these reports, there were naturally summaries of the causes of various production accidents and their final solutions.
Therefore, after years of illness, he actually learned a thing or two about how to deal with these accidents. Later, he wasted three years studying on his own, hoping to be admitted to the engineering team to change his fate.

only……

For people without connections, ideals are full of hope, but reality remains skeletal.

It was the failure in the internal examination that made Yang Mo think about resigning completely, and from then on he started an exhausting career of adventure... Of course, this is a story for later.

………………

In the technical room, Yang Mo was sitting on a chair, writing and drawing on paper and giving orders.

Yang Mo: "Tell me the equipment and drill pipe models used in Well No. 1!"

小王：“8寸半钻头1个，7寸钻铤3柱，6X2寸钻铤2柱……剩余的，就是5寸钻杆了。”

Yang Mo nodded: "It's all according to the construction drawings. There is no violation of any regulations... What's the reading on the weight meter?"

Sun Jian: "Plus or minus 60 tons."

Yang Mo: "Well, under normal circumstances it should be plus or minus 80 tons... What is the reading of the mud pump pressure gauge?"

Sun Jian: "15 MPa!"

Yang Mo: "Well, under normal circumstances it should be 12 MPa... 1849 meters deep, 15 MPa pressure, plus a reading of plus or minus 60 tons on the weight scale... I guessed right, it should be the well wall collapse... This is the most common type of sand-settling drill bit jam, which is what you call a well leak."

Hearing the word "well leakage", Sun Jian breathed a sigh of relief, but his heart was in his throat again - although well leakage would not threaten lives, it would delay drilling for ten days or half a month at a time, seriously delaying the drilling progress!
Thinking of the extremely generous year-end bonus the company promised for this major battle, Sun Jian licked his face and handed over a cigarette: "Master Yang, look... the engineering team hasn't given us a definite answer yet, what should we do now?"

Seeing Yang Mo's calm demeanor and the parameters he reported that laymen would never understand, for some reason, Sun Jian had more confidence in him and even upgraded his address from "Master Xiao Yang" to "Master Yang". He took the cigarette handed over by Sun Jian and took a look.

Oh, it’s the old stone forest that has long been out of print in later generations.

Suddenly, the old smoker in his body revived and lit the cigarette with Sun Jian's kerosene lighter. After his lungs felt the mellow and spicy stimulation again, Yang Mo looked at him with a smile: "Don't worry... Master Xiao Wang, have you done the deep well water sample analysis?"

Xiao Wang nodded, rushed out of the train room, and hurriedly ran back with a document in his hand: "The water sample analysis results are out. The specific gravity of the clear mud is 1.05g/cm, and the mud viscosity is 20~23 seconds."

Yang Mo shrugged: "Although this matter is very troublesome to operate, the solution is not difficult...Captain Sun."

Sun Jian was immediately shocked when he heard this: "Master Yang, go ahead."

Yang Mo calculated on the paper for a long time: "The most urgent task is to increase the viscosity of the deep well mud... If the mud viscosity is not enough, it will be useless no matter how high the power of your drilling rig is... Hurry up and have someone prepare the mud treatment agent and inject it into the circulation tank to increase the viscosity of the deep well mud to 55~60 seconds to achieve the required performance underground... Remember, the specific gravity of the clear mud must be controlled at 1.25gcm!"

As he spoke, he wrote down a set of numbers and handed them over: "This is the ratio of the mud treatment agent roughly calculated based on the mineral content of the local clean water... The ratios of heavy metal powder, CMC, and other treatment agents are all included... Although the thickening effect may vary, it should not be significant."

Looking at the densely packed material proportions on the piece of paper, not to mention Sun Jian, even the technician Xiao Wang next to him almost popped out his eyes - what a joke, even if those experienced masters from the engineering team came, it would be impossible for them to calculate the proportions of the mud treatment agent in such a short time after getting the basic data!
They subconsciously thought that Yang Mo was fooling them, but after looking at the densely packed materials and proportions marked to one decimal place, they felt that it was not quite like that - it didn't seem like he was fooling them so seriously. Besides, with no foreign aid now available, they could only try their best to get the generous year-end bonus.

kindness……

People who have not participated in the oil field production campaign have no idea how heavy the drilling tasks are for these drilling teams. As long as the planned progress is delayed for more than seven days, the bonus can basically be declared a loss.

Seeing Sun Jian calling his apprentice over, handing the note to him, and sternly warning him, the young apprentice hurriedly led people to make mud treatment agent. Yang Mo smiled at Sun Jian and said, "Although it takes a lot of time to prepare and inject the mud treatment agent, as long as this thing is injected, the rest will be much simpler."

Sun Jian was itching to do it, and asked half-doubtfully, "Master Yang, didn't you say that the drill bit is the most troublesome? Why do you mean... injecting mud treatment agent will solve the problem?"

Yang Mo laughed: "Of course it's not that simple. After the mud treatment agent is injected, you need to pour out the drill pipe along the sand settling point. Since you used 5-inch casing rods before, you will need to prepare 8-inch casing milling barrels in advance, and then mill to the stuck point;"

"Later, we need to lower the original drilling tool assembly into the wellhead and salvage the remaining drilling tools out of the well. Of course, all of this requires detailed well data support. Master Xiao Wang's surveying and mapping work is estimated to take until tomorrow afternoon. In addition, the previous work is extremely time-consuming, so this matter does not need to be so urgent for the time being."

After briefly describing the follow-up work, Yang Mo shrugged and said in a comforting tone: "In fact, in most cases, the most troublesome part of a stuck drill is to diagnose the cause of the accident and come up with a solution based on the geological conditions. As for the operations I just mentioned, as long as you are careful and cautious, and I am watching you, there is no technical difficulty at all."

"We should be thankful that Well No. 1, where the drill got stuck, was a directional well, and the location of the jam was less than 4500 meters in the shallow geological layer, so the difficulty was not great... If the jam was in a deep well over meters, it is estimated that our team would not be able to complete the company's production campaign task on time this year!"

Listening to the shameless Versailles words of a certain reborn person who had read the accident report materials at that time, Sun Jian and technician Xiao Wang almost burst into cursing.

There is no technical difficulty at all... Please be a human being!
A certain reborn person saw the reactions of the two people and almost laughed his belly off...
