Opening the Oil Reservoir Evaluation Research Room (Special Development Research Institute) of Sinopec’s Successful Oilfield Exploration and Development Research Institute Office) Party Branch Secretary, Deputy Manager, and Senior Engineer Cheng Ziyan’s experience will show that in the 16 years of working in the oil field, she has experienced in multiple positions, including heavy oil thermal recovery and development, unused reserves evaluation, shale oil efficiency Development… “What has changed is the position and the surrounding environment, but what remains unchanged is always the original intention of ‘I contribute oil to the mainland.’” Cheng Ziyan told all media reporters of China Women’s News.
Behind this insistence on “remaining true to the original intention” is Cheng Ziyan’s 16-year struggle to overcome difficulties day by day. When engaged in the development of thermal recovery of heavy oil, she led the team to establish a horizontal well thermal recovery development model, which filled the gap in this research in the world; in the attempt to evaluate unused reserves, she led the team to establish for the first time a model that is suitable for unused reserves in successful oil fields. The quantitative classification and evaluation system of reserves has achieved a breakthrough in increasing the built production capacity from 225,000 tons to 1 million tons during the “Thirteenth Five-Year Plan”; participating in the shale oil benefit development project, she and her team designed multiple Jiyang shale oil ports After the development of horizontal wells was put into production, the peak production exceeded 100 tons, setting new international shale oil single well production records… She herself has also obtained 2 national invention patents, 5 practical new patents, 1 software copyright, Sinopec Group Corporation He won 3 Outstanding Contribution Awards and 6 Oilfield Science and Technology Progress Awards, and was awarded honorary titles such as March 8th Red Flag Leader of Shandong Province, Victory Oilfield Labor Model, Outstanding Communist Party Member, and Outstanding Young Intellectuals.
“Many people asked me privately, haven’t I been lazy, never felt hard or tired these years?” Cheng Ziyan said calmly, “To tell the truth, sometimes it’s true I’m a little tired, but my deep love for working in the oil field is enough to withstand all the hardship and fatigue. ”
“Treasure Box” Girl
In 2006, Cheng Ziyan, who graduated from China University of Petroleum (Beijing) with a master’s degree in oil and gas field development engineering, got her wish. She joined Chenggong Oilfield Branch and engaged in the oil field work she loved.
Cheng Ziyan, who had just entered the workplace, once attended a meeting with new colleagues, and at that time she signed a contract with herself. Two agreements: one is the “five-year agreement”, to become a technical backbone within five years of working, and be able to take charge of the department; the other is the “ten-year agreement”, to become a “technical master” ten years after graduation, I have made great achievements in professional research.
“With these two agreements and my yearning for life, I started my personal work life. “Contrary to the emphasis on practical study in university, Cheng Ziyan found that application and practice at work are more important. In order to improve herself as soon as possible, she did not miss any opportunity to enter the work site and “mentor and mentor”, and actively participated in various projects When conducting research on key issues, I would ask if I met someone who didn’t understand something.
“Many apprentices were too busy at that time and were a little afraid of me. “Cheng Ziyan said with a smile. But it was such “shameless” asking for advice that made Cheng Ziyan improve quickly. In 16 years, she accumulated 33 notebooks. Colleagues would ask her if they couldn’t find information, and they gave her the nickname “Treasure Box” . This not only allowed her to quickly complete the “five-year agreement”, but also gave her the confidence to be a “vanguard” of petroleum research.
The pain and joy of “starting from scratch”
20Jamaica Sugar In 2013, Cheng Ziyan received an order to go to the newly established oil reservoir evaluation room as a technical backbone. “In fact JM EscortsSome people were dissatisfied on my behalf, feeling that I was “a bit of a loser” because I had just “cut my teeth” in heavy oil mining and had to go to a brand new department. “But Cheng Ziyan feels that no matter where she works, she is doing it. As long as she works hard, there will be no “suffering”.
After arriving at the job, Cheng Ziyan quickly adjusted her status and devoted herself to The research room is being set up and the work is being started. Sinopec as a whole does not have a set of evaluation methods specifically for the effective utilization of unused reserves. The accumulated experience is not practical and everything needs to be started from scratch.
forTo successfully complete this mission, she did not miss every opportunity for training and transportation, consulted experts, studied with brother units, and spent time in the office every day making deductions and calculations over and over again. With unswerving perseverance, after 7 months , tens of thousands of debugging simulations, Cheng Ziyan finally successfully completed the numerical simulation study of flooded heavy oil reservoirs in the Caonan Development Zone, becoming a precedent for Sinopec to independently undertake large-scale numerical simulations, and winning unanimous recognition from industry experts Jamaica SugarRecognize. After that, she faced the key issues that restricted the effective development of oil reservoirs with extremely heavy oils, sensitive heavy oils and other borderline heavy oils. She bravely became the first “crab eater” and undertook and completed multiple numerical simulation projects, including The thin interbedded heavy oil water flooding thermal recovery project of the Cao 13 Sha4 section of the Le’an Oilfield has the largest numerical simulation of heavy oil reservoirs in the oil field in terms of grid node scale. “At that time, new tasks came one after another. Under the leadership of the leader, the team members were more motivated to tackle the difficulties, exploring and trying one by one to overcome the difficulties.” Cheng Ziyan recalled.
After three years of success, Cheng Ziyan and her team established for the first time a quantitative classification and evaluation system suitable for the unused reserves of Chenggong Oilfield, effectively leading the annual pre-setting and mid- and long-term planning of the new area. and other tasks, which were judged by the expert group to have all reached the internationally advanced level.
“The job of motivation must be in your own hands”
At the end of 2019, a new challenge once again loomed before us—Jiyang shale oil showed excellent prospects for exploration and development. In the more than 60 years of exploration and development history of Chenggong Oilfield, this is a type of oil reservoir that has never been touched before. “Before this, we didn’t even know what shale oil was.” Cheng Ziyan said frankly. As the chief engineer of oil and gas development at the time, she led her team to consult with university teachers, learn from brother oil fields, consult thousands of documents, and work together to learn and tackle difficult problems.
Shale oil development has many unexpected difficulties. On December 31, 2020, the first evaluation well Niuye 1-1HF was drilled by Jamaica Sugar Daddy designed by Cheng Ziyan’s team Encountered a crack, oil and gas showed active, and well kick and leakage occurred on site. Due to comprehensive considerations of safety and efficiency, the well had to be drilled ahead of schedule. “We were originally reporting on another project, but after receiving the news on the way back, everyone became silent.” Cheng Ziyan recalled, “At that time, the well had only been drilled for 158 meters, and it was not yet our design One-tenth of the length according to international shale oil.Gas development experience shows that production is inversely proportional to horizontal section length. We are worried that the later production of this well will not be as expected, and we are even more worried that Jiyang shale oil development will fail. “
After returning to the office, many people in the project team couldn’t help but shed tears. “We have paid too much for this project.” “Cheng Ziyan lamented that the team members regard shale oil development as their own work and treat each well as their “child”. Fortunately, this first development evaluation well “contains the infinite love of the team” It exceeded expectations and achieved high production, providing strength for later work. At present, Cheng Ziyan leads the team to initially establish a design method for sweet spot evaluation and development optimization of Jiyang shale oil, and has compiled two development pilot test well groups to achieve the level of production. The peak oil volume at the wellhead is more than 100Jamaica Sugar Daddytons, breaking the international single-well peak production record.
October 21, 2021, is an unforgettable day for Cheng Ziyan. “General Secretary Xi Jinping came to the oil field for inspection, and the first stop was our Prospecting and Development Research Institute. “Cheng Ziyan had the honor to listen to General Secretary Xi Jinping’s instructions at the scene as a representative of scientific researchers, “I will firmly remember the General Secretary’s instructions, and the job of energy must be in my own hands. “Cheng Ziyan said decisively that there is no obstacle that cannot be overcome. She will continue to take root in the fields of unused reserves and shale oil, stay at the forefront of oil development and scientific research, and use scientific and technological achievements to help the country’s oil development and protect the country.
