China Petrochemical News reporter Yan Pinghui, Wang Yibing, Cheng Lipei.
On January 23, the reporter came to the Research Institute of Petroleum Exploration and Development, and when he walked into Ji Bingyu's office, he was deducing a bunch of mathematical formulas at his desk. On the desk next to it, there is a thick stack of books, including oil development, mathematics, artificial intelligence, etc., the pages of which have been turned to the edges.
Ji Bingyu, an expert who enjoys special allowances and the chief expert of the group company, has long focused on reservoir engineering, reservoir numerical simulation and enhanced oil recovery technology research, and recently won the 2023 Sinopec Science and Technology Innovation Meritorious Award.
Since joining Sinopec in 2008, he has led the team of the Institute of Petroleum Exploration to innovate the numerical simulation technology of complex carbonate reservoirs, which has provided strong support for the development of China's overseas projects. He led the numerical simulation technology of carbon dioxide incomplete miscible flooding, and has been used in the evaluation and test of carbon dioxide flooding potential of the group company. He led the team to independently develop a domestic shale gas numerical simulation software, and made important contributions to the increase of reserves and production of unconventional gas fields such as Fuling gas field.
By chance, he became attached to oil and overcame the problems of overseas projects with a bull's energy
Speaking of growth, Ji Bingyu took out a copy of "Petroleum Geology", and the pages of the book were already yellowed. "I started out in hydrogeology. Ji Bingyu said, "Back then, after studying this book, I had the confidence to do a good job in the new field of petroleum." ”
From an unknown student with the wrong major to a petroleum expert recognized by the industry and constantly making breakthroughs, achieving such a leap is inseparable from Ji Bingyu's super self-learning ability and a strong spirit of "doing what you do well".
In 1963, Ji Bingyu was born in the countryside of Changling County, Songyuan, Jilin Province, in a very remote location, "you have to walk 5 miles to go to school", and the school's teachers are very weak. Ji Bingyu said that thanks to those days, he cultivated a certain self-learning ability and a good spirit to do everything well, which benefited him all his life.
After graduating from Changchun Institute of Geology with a major in hydrogeology, Ji Bingyu was assigned to Daqing Oilfield, the largest production base in the country at that time.
At that time, I was holding back my bullish energy, and I wanted to see if I could do a good job in petroleum. Ji Bingyu said that I borrowed books related to petroleum from my colleagues, and when they studied them once in school, I studied them myself five times.
At that time, Ji Bingyu's dormitory was a four-person room, and the dim lights reflected his nights for several months. In the professional examination a few months later, Ji Bingyu stood out and became the first in one fell swoop.
This energy was also used in his later scientific research work. In 2008, in order to make up for the shortcomings of the upstream and increase production, Sinopec set its sights on overseas blocks, and the Research Institute of Petroleum Exploration and Development began to expand the oil and gas development research team.
The first project they ushered in was the development of an oil field in the Middle East. As the project leader, Ji Bingyu led the team to carry out technology research and development.
The oilfield is a super-large carbonate reservoir with serious reservoir heterogeneity, mixed and interlaced sweet spots and poor oil parts, and rich asphaltenes, which has high requirements for well trajectory optimization and production process control. However, the methods at that time could not meet the needs of accurate reservoir description.
The development concept of overseas oilfields is different from that of domestic oilfields, and more emphasis is placed on modeling, digital modeling, and process. Ji Bingyu led the team to flip through books, read **, brainstorm with experts and scholars at home and abroad, read the technical information of major foreign oil companies, and continue to learn.
He led the team to break through the limitations of international experience and practice at that time, carefully carved the reservoir according to the petrophysical properties, subdivided 6 pore characteristics, and found a suitable algorithm for each of them, which took 4 years.
In the end, they innovated and formed key technologies such as geological modeling based on rock types and multi-phase and multi-component parallel numerical simulation, which increased the drilling rate of high-quality reservoirs from 30% to 80%, controlled the precipitation damage of asphalt in the reservoir, and increased the production rate from 75% to 92%, making outstanding contributions to the smooth development of the overseas oilfield. The project won the second prize of the National Science and Technology Progress Award.
Shushan learned to be a "petroleum mathematician" and led the team to successfully develop the first shale gas numerical simulation software Compass
Talking about hobbies, Ji Bingyu showed reporters a university textbook "Advanced Mathematics" in the 80s of the 20th century. This was his earliest textbook for advanced mathematics. Ji Bingyu can become a well-known expert in the field of reservoir engineering, which is closely related to his good mathematical foundation.
In 1978, the first issue of "People's Literature" published Xu Chi's reportage "Goth's ** Conjecture", which influenced Ji Bingyu's generation. "Since then, I have felt that mathematicians like Chen Jingrun are heroes. Ji Bingyu said.
Interest is the best teacher for people, and a seed of love for mathematics takes root in Ji Bingyu's heart. Since then, no matter how busy he is, he has read several pages of professional books on mathematics every day, and he has never stopped.
When he was young, he went out for training for 2 months, and he went to all the local bookstores, found more than 20 mathematics textbooks, and began to study them hungrily, which was just the tip of the iceberg in his mathematics learning.
Mathematics brings a way of thinking and a way of thinking. Ji Bingyu said. Later, Ji Bingyu applied for a doctoral degree at the Institute of Systems Science of the Chinese Academy of Sciences to study systems engineering, which brought a broader vision and a better way of thinking to Ji Bingyu's oilfield development work. "The main thing to learn is holistic thinking, quantitative thinking and long-term thinking, which are exactly what is needed for oilfield development. Ji Bingyu said.
Around 2018, as conventional oil and gas production entered a bottleneck, more and more oil people began to focus on the unconventional oil and gas field, and shale gas and shale oil became hot words in the industry.
Previously, the reservoir numerical simulation software used in China's oilfields mainly came from foreign companies, which was expensive and not highly compatible with the actual development of shale gas fields in China, which restricted the development and development of gas fields. China's software localization is also in full swing.
We will study what the oil field needs. Ji Bingyu said that he began to set his sights on the independent development of shale gas numerical simulation software.
How easy is software development? First of all, it is necessary to have talents who understand both professionalism and programming. In this regard, Ji Bingyu aimed at students who had not graduated from Tsinghua University, Peking University and other universities, and went directly to the campus to poach people. Dai Cheng, the technical backbone of the project, was "dragged" to the hospital by Ji Bingyu on the eve of graduation from Peking University.
At that time, Dai Cheng actually preferred to stay in colleges and universities to teach, Ji Bingyu found him and said: "You are studying engineering, engineering should not only stay in books and **, only to truly meet the needs of the country and enterprises, engineering is valuable." This sentence deeply touched Dai Cheng.
The flow of shale gas underground is different from that of traditional reservoirs, and the first technical problem to be solved in order to make software is to establish a mathematical model of shale gas flow underground.
When we had problems with mathematics and seepage mechanics, we would ask Mr. Ji, and he would take the trouble to give us guidance. During that time, as long as he walked into the office of the general manager, he was either calculating formulas on paper or gnawing on professional books. Xia Dongling, a colleague of Ji Bingyu and director of the Oilfield Development Research Institute, said, "We all call him a petroleum mathematician." "With the continuous efforts of the team, we have successfully built a mathematical model that reflects the characteristics of shale gas extraction.
With the mathematical model, the practicability of the software has become Ji Bingyu's greatest concern. In this regard, he led the team to apply software engineering methods to develop software, and led the team to the oilfield many times to solicit the opinions of employees at all levels on the use of software.
In the end, the compass shale gas numerical simulation software with Chinese characteristics developed by them was put into use in Fuling and other gas fields, which played a great role in the daily production and increase of reserves and production in the gas fields, and was widely praised by employees in the process of use. At present, Ji Bingyu and his team are exploring the application of Compass in more scenarios.
At the age of 60, he began to learn the Python language by himself, actively integrated into the general trend of artificial intelligence development, and solved work problems and learned new things
When asked what book Ji Bingyu was currently reading, he took out an original English version of "Artificial Intelligence", which is a new field he has been researching recently.
This is the total treasure now, when I go on a business trip, I see it in the car, on the plane, and when I arrive at the hotel, I still look at it. Xia Dongling said. The young people in the team all know that Ji Bingyu has been teaching himself the python language recently, and sometimes he is ashamed to ask questions, catching young people and asking non-stop.
Ji Bingyu said that to dry oil, it is still necessary to master more cutting-edge knowledge, so as to keep pace with the times and better serve production.
I've been working with Ji for a total of 12 years, and I haven't seen him not study a day. Xia Dongling told reporters, "When he encounters a field that he doesn't understand, his first reaction is to buy books and study. ”
Reading, thinking, and then acting, looking back on Ji Bingyu's career, it seems that he is a student, who has been digesting and absorbing new knowledge, and has been doing some pioneering explorations.
China's heavy oil resources have billions of tons, most of them are buried deeply, in recent years, the quality of China's remaining oil resources has been declining, how to better exploit heavy oil resources has become a topic of widespread concern in the industry.
The traditional way of heavy oil development is steam huff and puff, and then transfer to steam to drive oil. This method is effective in the early stage of heavy oil exploitation, but after multiple rounds of huffing and puffing, due to the deep burial of heavy oil, the problems of rapid production decline, high cost and low recovery efficiency are becoming increasingly prominent.
With the support of the main leaders of the Institute of Petroleum Exploration at that time, Ji Bingyu began to research and explore the subversive heavy oil chemical flooding cold recovery technology on the basis of the traditional heavy oil thermal recovery.
The project explores a new approach to green and low-cost development of heavy oil, which is expected to slow down the production decline of heavy oil reservoirs after multiple rounds of huffing and puffing, further improve oil recovery, reduce costs, and reduce carbon dioxide emissions. The project has been selected into the advanced practical technology catalogue of the Ministry of Natural Resources, and has opened up demonstration areas in some oilfields and achieved preliminary results.
Now, Ji Bingyu has combined his newly learned artificial intelligence knowledge with previous knowledge in the field of oilfield development, and is keenly aware that powerful artificial intelligence can be used to mine the current massive production data of high-water-cut oilfields, so as to deepen the understanding of the production law of ultra-high-water-cut oilfields and lay the foundation for further improving the effect of oilfield development.
In addition, with the establishment of the "dual carbon" goal, Ji Bingyu's research direction has also moved closer to green technology, expanding the research of carbon dioxide flooding technology to CCUS (carbon dioxide capture, utilization and storage) technology, and realizing carbon dioxide emission reduction and storage while achieving carbon dioxide recovery efficiency.
The baht must be more national, and the first thing to do is to be the first, and the jade is in the future. Ji Bingyu said that this award is just a new starting point, and in the next step, he will pay more attention to the training of young people in the team, so that the scientific research strength in the field of oil and gas development will be passed on from generation to generation.
