"First of all, let me tell you. What is tertiary oil recovery? The second oil recovery does not guarantee production. The third oil recovery came into being. Water injection is the key word for secondary oil recovery. The key word of the third oil recovery is injection and agglomeration. Actually, there are other methods, but here we use the method of injection and aggregation to recover oil. We inject the prepared polymer into the ground, and the polymer is adsorbed in the oil layer, and the reaction produces a series of complex effects. Eventually wash the oil out. The resulting oil is pumped out, thus ensuring production. Such a yield increases many times in terms of water injection.

I'm going to walk you through the process now. The process is divided into the following steps. Proportioning-dispersion-maturation-pumping-filtration-storage tank pressurization metering-proportional dilution-mixing-injection These steps I will first briefly introduce to you, the detailed content, and wait until the scene, I will let you feel it intuitively, and then explain it in detail. Easy for everyone to understand.

The following kinds of raw materials are required for proportioning. The ternary is water, polyacrylamide, and sodium bicarbonate. There are also binary ones that are water and polypropylene millamine.

This station is a three-way drive. I will follow the process of this site below. At the station of the binary drive, I will introduce you to the process of binary.

The ratio is calculated artificially and the parameters are set. I'll skip it for now.

The dispersion system is the device in front of you. On the computer are drawings. I'll take you to see it live. The eldest brother said as he switched the pages of the computer to a scattered area

"Polypropylene millamine is added here. This pump drives, passes through the pipe, and fills it with water. Sodium bicarbonate is added here. Mix and stir.

Mature in jars.

Output through the pump. Filtered. Inflow into the injection area. There are jars in the injection area. It is diluted by machine proportioning and water injection. Mix. Finally, it is injected into the ground by a pump. That's probably how it goes. The eldest brother said as he clicked on the computer screen with his mouse.

Wang Yan can clearly feel that this is an unknown territory. When she came here, everything had to start all over again. She is curious about the unknown, and she is confident that she will use this curiosity to remember everything about this place. Familiar with the process and thorough knowledge. Get the groundwork right. She believes that her efforts will create a great future for herself.

"Yesterday, I informed everyone to wear flat shoes. If there is someone wearing high heels, just wait outside and cannot go in. The girl tied her scalp all the time. If the hair is too long. The big brother paused. He said to the eldest sister beside him; "Sister Li, please find a few hats." The eldest sister left the house.

"It's better for girls to have their hair tied up and wait a while. Sister Li brought the hat. Come in with me with your hats. ”

"It's a real nuisance."

"Be understanding."

The first stop for the eldest brother and everyone was the material warehouse.

Tall bags are neatly stacked inside. He told everyone. This is polypropylene millamine. One bag is 0.75 tons. Everyone was surprised and shocked.

Feeding device. Lift the bag with a sky crane and open the bag. The contents are added to the inside. The device is running, and these things are added to the dispersion. The first time I saw the appearance of polypropylene millamine, everyone was curious. Wang Yan also came closer to take a look. She looked at the sugar-like particles and wanted to touch them with her hands, but she was afraid that they would be harmful. After a little entanglement, he didn't reach out. She knew it was polymer, and she was working here and it was intimately entangled.

Scattered giant funnels. Water pump. Filter. Maturation tanks. Filter. Filter bags. High-pressure pumps. centrifugal pumps and more. Some professional knowledge popped out of the mouth of the eldest brother in turn. Everyone is very fresh, and they are also shocked by everything fresh here, and they feel that the eldest brother is very professional. I also admire this big brother.

Wang Yan saw that the ground in the equipment area was covered with large tiles with white as the main tone. The tiles were very clean. The equipment was also very clean. Dust secondary doesn't seem to have anything to do with here. She's a little incredible.

The stationmaster and squad leader of this station came here to introduce the glorious honor of this station to everyone. Reading between the lines reveals the benefits of everyone choosing to stay here. I hope that when you choose a squad, you will take the initiative to ask to come here.

After the tour, everyone left the place. Head to a mid-configuration station with a binary displacement predominant. According to the eldest brother, the road to this station is easier to walk.

The bus travels through bumps and eventually reaches the end point.

Wang Yan calculated the time, and the drive was 30 minutes.

The process is similar. The crowd entered. Wang Yan followed everyone. It was found that there were more than a dozen maturation tanks standing outside the station. There were only four of those stations just now. In terms of size. The maturation tank at this station is an adult, and the maturation tank at that station is a baby. The floor of the factory is still paved with white tiles. The equipment is as clean as the previous station. Wang Yan was thinking about a question, whether it was not easy to fall into dust, or artificially wanted them to see that it was so clean.

Towards the end of the visit. The team leader makes a surprise visit. It's like it's booked early, just waiting for everyone.

This leader is more talkative than the superior. He talked about the development prospects of the experimental brigade as the topic, and talked about the good things here. It tells that if someone comes to work here, there will be development and benefits. If you go to work in the mines, it's not as good as here. There is a motorcycle life, and here is vibrant. The combination of professional words and homely words, from time to time, pops up some Internet words commonly used by young people, which is obviously carefully prepared.

And they all knew it in their hearts. The purpose of this leader and the superior leader is the same, so that everyone chooses to come here.

The captain of the three-yuan drive came in a car, and the two captains met. Greeting each other. The atmosphere in the greetings was-for-tat. Wang Yan could feel that the contradiction between the two was not the slightest bit. Freezing three feet is not a day's cold.

The eldest brother who led everyone said to everyone. Both squads were short of people, and both captains were eyeing our group in the hope that more people would work with them. People need to understand their hearts.

Wang Yan stared at the factory, a little sad. This sadness is only a flash and it is relieved. She secretly said in her heart that since she chose to be here, she must be here. What others can do, you can do yourself. She thought that if she stayed here to work, she would be with Su Peng sweetly for a lifetime. Working here by yourself would have left my mother and uncle speechless. She wants to break out of her own sky like Yan Xin's cousin. I don't know what kind of story my aunt has when she goes to my cousin. She left a message for her cousin on WeChat, but the cousin ignored her. He should be anxious to deal with his aunt now.

At that time, she didn't know what kind of impact her persistence would have on her in the future. How far is the future of staying here to work and the future she imagined.

After returning home, Wang Yan shared with her mother what happened today, and after Yan Yan listened patiently, she left a sentence: "It's good if you're happy." ”
