At 3 am on July 5th, at the experimental building of the Northwest Petroleum Scientific Research and Production Park in Northwest Sinopec, a window was also shiny. Excessive reason. "The results of the 73 on -site use of the chemical agent benzene and the test results are normal. What is the reason for the excessive standard?" The problem does not solve it.

How to stick to thick oil? Can the chemical adhesion method be used? How to use? How to save money? ... In order to solve these problems, Yang's motherland and his scientific research team have worked hard for 15 years.

In order to start the first battle of chemical reducing adhesion, from 2007 to 2009, Yang's motherland has been participating in the adhesive pilot test. Once each experiment starts, it cannot be interrupted. Pharmacy deployment, pipeline connection, pump pressure monitoring, segmentation adjustment ... A experiment requires more than 20 hours in a row. In order to be able to grasp the data more accurately, each time Yang's ancestors were in the experiment, it was like a demon, staring at blood red eyes, carefully observed each data change, and carefully recorded each. Species parameters.

With more than two years of theoretical research and on -site practice, Yang's motherland and colleagues have proposed that "reducing adhesion development should return to thick oil to cause adhesive sources to achieve the concept of efficient, stable, and economy." With this concept support, the Northwest Oilfield has built a 3 million -ton deep super thick oil development demonstration oil field.

The thick oil of Sinopec's northwest oil field is different from conventional oil, and the shapes are all kinds of from slag -shaped to sticky. In August 2012, Yang's motherland received the task of continuing to carry out the development of ultra -deep well ultra -thick oil efficient chemical reducing systems to find the most suitable chemical reducing method.

The most basic step of developing adhesives is to take samples for experiments.

One -handed hammer shovel with one hand, and there was a big bucket on his back. The samples of Yang's motherland in the specimen room built in the color steel board house have made it difficult for colleagues to forget. The specimen room is cold and hot in winter, and the high temperature of more than 40 degrees Celsius in the summer makes Yang's motherland's work clothes quickly soaked. The pungent smell of various samples smokes his tears. The sampling room in winter is frozen like an ice cellar. The sample oil is more freezing than stones. Yang's motherland uses shovel, shovel and shovel, and after two or three hours of samples, his hand is filled with blood bubbles. Essence

However, these are not really suffering in Yang's motherland. "When it is in the bottleneck of R & D, it is the most painful." Yang's motherland said that on the road of closing the ultra -deep and thick oil chemical reducing adhesion, there is no experience to learn from, and every step is very difficult.

In the first half of 2014, it was the most difficult day for Yang's motherland and colleagues. The preliminary evaluation effects of a variety of water -soluble adhesives introduced by the survey for several months are not satisfactory, and the road seems to be dark. How to do? At the time of everyone, a technology company found Yang's motherland, saying that they had a reducing adhesive for high viscosity and thick oil, and the effect was good. Yang's motherland immediately communicated with the company and stepped up the experiments. Repeated experiments have been experimented dozens of times before and after. "Breakthroughs!" At two o'clock in the morning, he couldn't wait to call the unit leader's phone call and report the good news.

Next, through repeated experiments to improve the proportion of adjustments, Yang's motherland and team innovatively developed three high -efficiency chemical adhesive systems, which have been promoted and applied to large -scale, successfully achieved ultra -thick oil chemical reducing adhesions, and obtained obtained The three national patents have improved my country's international competitiveness in the chemical preparation system of high temperature and high salt, high -salt and high salt, and the chemicals system.

For a while, the tactics of adhesives were tested for a while, and Yang's motherland began to study how to optimize each stick reduction details to ensure that the adhesion effect was better. At present, under the leadership of Yang's motherland, ultra -deep ultra -thick oil chemical reducing adhesion supporting technology, chemical adhesive and efficiency and increase technology, efficient lifting technology, and accurate configuration technology of adhesives have been made breakthroughs, and many invention patents have been obtained.

"For those who are scientific research, it is like a climber. When you conquer a steep peak, there will be a higher peak waiting for you." Yang Zuguo said that as a petroleum, life is not only scientific research not only scientific research If you do n’t, you can contribute to the high -quality development of the oil field.
