After 1:00 p.m. on April 25, Chen Xiao was still sitting at his desk processing data, he looked at today's task list, docked with the external team in the morning, held a well position demonstration seminar in the afternoon, and studied geological data in the evening.
"I could have gone home early today!" Chen Xiao calculated the time and said that he could leave work at 9 or 10 o'clock at night.
This is Chen Xiao's daily work, but also the daily life of oil and gas field geological exploration workers. Chen Xiao, 37, deputy director of the Institute of Oil and Gas Field Geology, Exploration and Development Research Institute, PetroChina Southwest Oil & Gas Field Company, is 37 years old.
Although young, Chen Xiao has been on this front for 11 years. He has won many honors such as "Ten Outstanding Youths" of China National Petroleum Corporation and "Excellent Communist Party Member" of The Exploration and Development Research Institute of PetroChina Southwest Oil and Gas Field Company.
In addition, Through research, Chen Xiao and his team took the lead in proposing new geological theories such as "developing volcanic rocks along the ancient fault zone of Longquan Mountain", innovated and formed key technologies such as complex mountain seismic imaging and three-dimensional fine carving of favorable geological bodies of carbonate rocks, and made important contributions to the exploration of The largest monolithic marine carbonate gas reservoir on china's land- Sichuan Anyue Gas Field, Sichuan Longmenshan Mountain Front Belt Ultra-deep Permian Tan phase gas reservoir, and volcanic rock in Jianyang area.
So far, as a "gas seeker", Chen Xiao and his team have accumulated proven geological natural gas reserves of hundreds of millions of square meters in the Sichuan Basin.
Research + diligence
He went from being a newcomer to a job stuntman
Trillions of gas reserves have been discovered
In 2010, Chen Xiao graduated from university and entered the Southwest Oil and Gas Field Company of PetroChina. As a researcher of geology, he was assigned to the Institute of Geophysics of the Research Institute of Exploration and Development, where he engaged in seismic interpretation work with a wide span of his major. "Researchers are ready to take on the challenge!" With this idea, Chen Xiao through research and exploration, learning to apply, he found that geological theory and seismic interpretation are naturally inseparable brothers, the combination of the two work ideas, helped him to complete various tasks excellently
In 2011, The Gaoshi 1 well in the Anyue area of the Sichuan Basin was shown to be important oil and gas. Through the research and analysis of tens of thousands of square kilometers, Chen Xiao and his team have revealed the geological characteristics of the superposition of deep low-altitude structures and large paleouples in the central Sichuan region, making important contributions to the exploration of the Anyue gas field, the largest monolithic marine carbonate integrated gas reservoir in China so far.
"With the most advanced technology, the most delicate work to ensure efficient exploration and development of large fields." Chen Xiao and his team quickly threw themselves into the study of the refined interpretation of three-dimensional earthquakes. Establish seismic response patterns of thin beach-facing reservoirs and small-scale fracture-hole reservoirs, and finely sculpt the spread rules of deep-shoal thin reservoirs. In the process of boring and arduous research, Chen Xiao explained the 240,000-kilometer two-dimensional and 25,000 square kilometer three-dimensional seismic data to a good job. Someone had done a test and put a cross-section without any markings in front of him, and he could immediately say where the line was located and accurately indicate the geological level.
However, when the major discovery of trillions of reserves in the Anyue gas field was commended, Chen Xiao had silently embarked on a new journey. Through hard work, he also established key geological models such as in situ structure under the thrust fault of Longmen Mountain in northwest Sichuan, innovated and formed complex mountain imaging technology, effectively improved the imaging effect of complex structures, led the deep high-fidelity and preservation amplitude treatment, and formed the seismic phase classification and evaluation of deep carbonate thin reservoirs, breaking through the bottleneck of deep exploration technology in Sichuan Basin.
"Deyang-Anyue rift trough depiction" and "Longmen Mountain front belt composite trap description" and other work has made significant progress, new geological understanding has broken out of the cocoon, double exploration 1 well, Pengtan 1 well and other risk exploration wells have been successfully demonstrated and major discoveries have been made, and a new trillion square atmospheric fields in the Sichuan Basin are just around the corner.
Pioneering + innovation
Break the "authority" to make a sound
He is a breakthrough in volcanic rock exploration
In 2015, during the interpretation process, Chen Xiao found an anomaly in the seismic amplitude of 100ms in the Jianyang area. He knew that a tiny anomaly could represent a drastic change in the geology of the subsurface, and such details could not be spared. Despite repeated research, the research work was impossible.
"Learning to think in dimension is a way to solve many problems." This is Chen Xiao's experience, the geophysical dimension is not enough, it is combined with the dimension of stratigraphic sedimentation; not enough, it is combined with the dimension of geotectonics. Chen Xiao took his research to a new dimension – prototype basin restoration.
Restoring the ancient geological background of the Sichuan Basin tectonics and sediments hundreds of millions of years ago is highly complex and difficult. Numerous "authoritative" views did not stop Chen Xiao's eyes from exploring, and he was concerned about an important geological event- the large-scale eruption of volcanic rock caused by the rapid uplift of the Permian Emei mantle column.
"Could it be controlled by fault zones, which extend north along the early Longquanshan fault zone?" The Panxi Plateau Large Volcanic Rock Province is the only internationally recognized ancient magma province in China, nearly 1,000 kilometers away from Jianyang. However, Chen Xiao still boldly established a geological model of volcanic rock, which was verified by digital simulation, and the simulation results were highly consistent with the seismic profile phenomenon. A major breakthrough was made in research, and he identified favorable areas for exploration of Jianyang volcanic rock.
In 2018, Yongtan 1 well obtained high-yield industrial air flow, Sichuan discovered a new scale exploration stratigraphy, natural gas resources of more than 400 billion square meters, volcanic rock exploration opened a historic new chapter.
This year marks Chen Xiao's 11th year of oil and gas exploration in the Sichuan Basin. Nowadays, the technical series such as seismic phase classification evaluation and fine description of phased reservoirs in deep carbonate beaches led by his team have broken through the technical problems of ultra-deep exploration and have reached the international advanced level.
In the past 11 years, Chen Xiao has traveled through the typical geological profile of the Sichuan Basin, turning through the seismic data of the basin and explaining the profile for more than 100,000 kilometers. Tenacity and dedication have been exchanged for 3 international standard characteristic technologies and 16 scientific and technological progress awards at all levels. In the future, this "qi seeker" will continue to carry a geological hammer and compass, wearing a red workman's suit and walking between the mountains in the southwest.
