Just as Wei Ying and the driller Liang Boyi were chatting, the technician Li Zhoujian and the deputy captain Niu Bing and Jie came over.

As soon as technician Li Zhou saw it, he pointed to the position of the wellhead turntable, and then said to the deputy captain Niu Bingjie:

"The Ox team, the third shift drilled into a day today, and it was less than a meter...... Look, are you going to drill it?"

Niu Bingjie frowned, feeling very stressed, and said:

"Then we have to afford to drill, otherwise, at this pace, we won't be able to drill a well in a year......

The drilling speed of the Changqing drilling team is very fast, and even created a myth called Changqing speed.

Put it in, if it is an oil well, then a week, you can drill a well,

If it is a natural gas well, it is the slowest and a month, and a well can be drilled.

However, if you come across the kind of well that drills the core, it is a different story.

Listening to the words of the deputy captain Niu Bingjie, technician Li Zhoujian immediately gave an order to the driller Liang Boyi and said:

"Liang Boyi, let's follow the instructions of the deputy captain Niu Bingjie, and start drilling ...... now"

Wei Ying was beside her, asked Li Zhoujian, and said:

"Master, do you judge, is the drill bit damaged?"

Technician Li Zhoujian followed the driller Liang Boyi into the driller's control room, and said to Wei Ying who was following him:

"It shouldn't be the cause of the formation, nor the cause of falling objects...... Now, only after we take the drill pipes out of the well and then take the drill bits out of the well, can we know what is causing the drilling speed to be so slow......"

Listening to the words of technician Li Zhoujian, Wei Ying thought in her heart:

What is the reason for the PDC drill bit, so quickly, that there is a problem?

At this moment, when the driller Liang Boyi walked into the driller's control room, he commanded the employees on duty and said:

"Stop drilling, now get ready to drill...... Zhang Jiaqiang, a derrick worker, is ready to go to the second floor...... Zhao Bo, an external fitter, and Wang Yushui, an internal fitter, are ready to unload the drill pipe at the wellhead...... Wang Zhizhi, the site worker, and Xie Eryang, the sitting-in worker, cooperated at the well site to neatly arrange the drill pipe to the pipe rack......"

After hearing the command of the driller Liang Boyi, all the employees present immediately began to divide and cooperate.

When Zhang Jiaqiang climbed to the top of the second floor, he knocked on the drill pipe to signal that he was ready.

And Wang Yushui and Zhao Bo, the elevator, lifted to the turntable.

Wang Zhizhi, the field worker, held the long warped bar, stood on the catwalk, and prepared to roll the drill pipe.

When the drill pipe was started, Wei Ying stood next to him, he stared at the drill pipe that was raised from the well one by one, asked Li Zhoujian curiously, and said:

"These drill pipes are made of special steel, which is very strong, why can't they drill the formation in front of them?"

Li Zhou Jianzai stared at the suspension table carefully, and then explained to Wei Ying, saying:

"Although the drill pipes look very strong, when you connect them one by one and go down to the bottom of the well, they work like noodles and are soft and ......."

Listening to the words of technician Li Zhoujian, Wei Ying felt very shocked,

Because, he never imagined that the drill pipe in front of him, when working at the bottom of the well, would be as soft as noodles.

So, Wei Ying felt it and said:

"It seems that it is not easy to drill a well more than 4,000 meters deep......

After speaking, Wei Ying asked the driller Liang Boyi and said:

"Liang Boyi, if you want to bring the drill bit out from the bottom of the well, how long will it take?"

The driller, Liang Boyi, made a rough estimate, and then said:

"At least a whole day...... Moreover, this is also under the normal condition of liquid-gas clamps...... If there is a problem with the liquid-gas clamp...... Then, it takes at least two shifts, that is, 24 hours, to be able to lift all the drill pipes out of the well and put the drill bits on the drill floor......"

Hearing that the amount of work was so huge, Wei Ying was mentally prepared, and she said:

"Liang Boyi, I know, there are not many workers in your class, if everyone is tired, you can come and call us, we will go up to the drill floor and change people......"

Liang Boyi has adapted to this kind of high-intensity work and life, she smiled and said to Wei Ying:

"It's okay, Wei Ying, since you are now, follow the technician Li Zhoujian and learn technology...... So, you don't care about our small class work...... Although it is a little bitter and tiring, we can definitely persevere......"

At this time, it is winter, the cold winter wax moon, when the workers are on the drill floor, after unloading the drill pipe,

The mud sprayed out from the drill pipe, and directly sprayed the drillers working at the wellhead into an iceman.

Wei Ying looked at the scene in front of her, and she couldn't help but think that at this time last year, when she was drying the wellhead on the drill floor, it was the same way, after being sprayed with mud, her whole clothes were as hard as armor.

Although, the weather is very cold, and the working conditions of the drilling workers are very difficult,

However, there are still smiles on everyone's faces, and the work is very high......

At this time, technician Li Zhoujian stood up,

As he walked out of the driller's control room, he said to Wei Ying:

"Okay, Wei Ying, let the driller Liang Boyi take the employees of their class to drill on the drill floor...... Now, let's go down and engage in the means of production......"

When Wei Ying followed the technician Li Zhoujian and began to do technical work,

What impressed her the most was that the technician had an endless amount of information.

Even, sometimes all night to do information,

However, even so, their work could not be completed on time.

I saw that at 8:00 p.m.,

Driller Liang Boyi's class finally brought out all the drill pipes.

They removed the PDC bit and put it on the drill floor.

Wei Ying followed Li Zhoujian and came to the top of the drill platform, the two of them squatted on the ground, studied it carefully, and turned their heads to the damaged PDC in front of them.

I saw that after Li Zhoujian looked carefully, she shook her head and said very regretfully:

"I really can't figure it out, what formation did we encounter in the first well we drilled at the beginning of this year, and why did a new PDC brick go down to the well and work for a long time, it will be ground off and the teeth will be cut?"

And Wei Ying was beside her, and she also clearly saw that a small black cutting tooth similar to a cylinder was directly ground off from the PDC drill bit.

Wei Ying touched the missing cutting teeth, and then said to the technician Li Zhoujian:

"Since, this PDC drill bit, when there is one less cutting, then, it will definitely not be used......"

Technician Li Zhoujian took out his camera and took a clear photo of the damaged PDC drill bit in front of him.

While recording, he said to Wei Ying:

"Wei Ying, wait a while, you go to the materials clerk and declare...... We had to use a new PDC bit, otherwise we wouldn't have been able to get into ......."

At 8:10, the third shift where the driller Liang Boyi was located also arrived at the end of work.

When the general successor employee came over, the driller Liang Boyi walked out of the driller's control room.

Liang Boyi said to Wei Ying very tiredly:

"Wei Ying, we're off work, when will you get off work?"
