In this case, Gu Xingshen could only change his tricks to make her some food for him.

"Come, I made a few dishes that you (Ai) ate today, come and try them!" The conditions in the small county town are difficult, and Gu Xingshen can only make the limited ingredients as delicious as possible.

Cheng Qingxue also joked: "You're going to feed me fat, you won't dislike me in the future." ”

As he spoke, he quickly picked up the meal, Gu Xingshen was worried when he saw her like this, so he walked over and patted him gently on the back to help her calm down.

"You eat slowly, no one will rob you, don't choke!"

With food in her mouth, Cheng Qingxue squeaked and said: "There are still some tools that have not been completed, we have to drive them out in the next few days, and they can be used when Jin Jianguo comes here to study in two days, and they can also be invested in our company when the time comes." ”

Hearing this, Gu Xingshen was really afraid that she would be tired: "Doing research is important, but it also has to be a combination of work and rest, what can you do if you exhaust your body, when you want to study again, your body can't stand it." ”

Knowing that he was for his own good, Cheng Qingxue said: "Don't worry, I know what I know, I'm almost done, I'll only teach him every day after I finish this, and there won't be any extra tasks." ”

And Gu Xingshen questioned her words, he really didn't believe that Cheng Qingxue could let go of geological research, but she would get bored if she talked too much, even if she didn't believe it, there was no other way.

On the day of class, Cheng Qingxue found that not only Jin Jianguo came, but even Luo Yu also came over.

Cheng Qingxue was puzzled, thinking that Luo Yu came to her for something (qingqing), and asked, "Why is Young Master Luo here too?"

I saw Jin Jianguo smile and said: "Luo Yu heard that I worship you as a teacher, and I also want to worship you as a teacher and learn geological knowledge." ”

And Luo Yu also jokingly said: "I have helped you a lot, if you don't agree to this little thing, it really hurts my heart." ”

Hearing this, Cheng Qingxue had no choice but to agree to let the two of them go to class together: "I don't know much, it's just that the aspects you are involved are different, and we can be regarded as communicating with each other." ”

After speaking, he took two people into the room that was temporarily cleaned up and used as a classroom for the time being.

As soon as Jin Jianguo and Luo Yu entered the room, they saw some strange tools placed in the house, and they were very curious, so they asked Cheng Qingxue: "Are these tools used in geological exploration?"

Seeing that they were interested in these tools, Cheng Qingxue did not hide it: "A large part of it is used in geological exploration, and some are used for other purposes, but they are all related to geology. ”

Jin Jianguo wanted to ask something more, but Cheng Qingxue knew that he had a lot to say when he saw him like this, so he said directly: "These will be used when you teach classes, just to tell you about their usefulness, don't worry, you will slowly understand in the future." ”

Hearing her say this, Jin Jianguo temporarily accepted the mind of studying these tools.

Cheng Qingxue sent them all the materials and books that had been copied in the past few days, but she didn't expect Luo Yu to come over to listen to them before, so she only prepared one copy of the book, so she asked the two of them to read it together.

Before class, Cheng Qingxue first told them about the time of class: "I will give you a class of forty-five minutes, and take a ten-minute break between every two classes, which will save my brain from accepting so much knowledge at once, and I can't digest it and feel tired." ”

Jin Jianguo and Luo Yu have no opinion on this.

Cheng Qingxue prepared a small blackboard and a few pieces of broken chalk for teaching.

"Today we will first talk about geostatic pressure, primitive formation pressure, saturation pressure and flow pressure, which are the most basic knowledge in geology. ”

Hearing him say this, Luo Yu also nodded in agreement: "I know the pressure of the primitive formation, I have seen it in some books before, but what is the saturation pressure and flow pressure?"

Jin Jianguo was also curious about this question, and he didn't know why Cheng Qingxue could always say something that they hadn't heard of at all, and this knowledge was all correct, and they couldn't refute it.

I saw Cheng Qingxue first write these two terms on the small blackboard, and then began to explain: "Under formation conditions, when the pressure drops to the point where the natural gas begins to separate from the oil, it is called saturation pressure." ”

The flow pressure refers to the middle pressure of the oil layer measured during the normal production of the oil well, which is called the flow pressure. ”

Hearing this, Jin Jianguo and Luo Yu hurriedly took out a pen and wrote it down in a notebook.

Jin Jianguo asked Cheng Qingxue: "These are all related to oil, what I want to know is what seismic detection principle was used when the mine was detected a few days ago, and what is going on?"

Cheng Qingxue quickly organized the language, and Cheng Qingxue told them: "The seismic detection method was used in the exploration of mines before, and the first thing we need to do is to conduct a disturbance wave survey to understand the types and characteristics of interference waves in the work area. After doing this, it is necessary to start a survey of seismic geological conditions to understand the characteristics of the low-velocity zone, the location of the diving surface, the presence or absence of the seismic interface, and the quality of the seismic interface (whether there is a seismic marker layer, velocity profile characteristics, etc.). Finally, the best conditions for excitation of seismic waves are selected, such as excitation rock (sexuality), excitation dosage, etc., and the best conditions for receiving and recording seismic waves are selected. It works ......"

Jin Jianguo and Luo Yu felt very benefited from listening to him talk about these things, and most of the time they followed him to take notes, only occasionally the two would interject a sentence to say something they didn't understand.

Even during the ten minutes between classes, the two of them did not let go, they had been discussing what Cheng Qingxue said, thinking about how to use it in practice, from minerals to oil to natural gas, although they had never heard of many things, but they were trying to digest these, even if there were times when Cheng Qingxue didn't pay attention and said something shocking, they just regarded it as their own short-sightedness and had not heard of it.

The day is down from class

, Jin Jianguo and Luo Yu both felt that they had benefited a lot, and Cheng Qingxue felt that although it was very tiring, it was also very meaningful to be able to tell them all this knowledge.

Seeing that it was not early, he left them at home for dinner: "It's not too early, why don't you go back after dinner at my house, there are a few points that I haven't made clear to you when I was in class just now." ”

Jin Jianguo had something to do with geology for a day, and he was busy responding, and Luo Yu naturally stayed.

Cheng Qingxue, who originally wanted to cook a few dishes by herself, didn't expect that when she went out, Gu Xingshen had already prepared a meal and was waiting for them.

Seeing them come out, Gu Xingshen pulled out the stool and said, "You guys finally came out, if you don't come out, this meal will be cold." ”

The three of them were busy sitting down to eat, but while eating, from time to time, they were still discussing the knowledge points that they didn't understand in class.
