Zhao Jinzhou's Representative Achievements

Comrade Zhao Jinzhou has been engaged in teaching and scientific research in the field of oil and gas engineering for a long time. He is a famous expert in oil and gas exploitation engineering and fracturing acidification in China. He has successively won the National Science and Technology Progress Special Prize 1, the National Science and Technology Progress Second Prize 1, the National Energy Science and Technology Progress First Prize 1, the Provincial Science and Technology Progress First Prize and the Technological Invention First Prize.

Comrade Zhao Jinzhou is the training object of the academician training project in Sichuan Province, the national candidate of the 100 million talents project in the new century, the academic and technical leader of Sichuan Province, the expert enjoying the special government allowance of the State Council, the outstanding expert with outstanding contributions in Sichuan Province, and the trans-century academic and technical leader of China Oil and Gas Group Company.

Through more than ten years of research and field application, a series of new models, new methods, new products, new tools and new technologies have been established and developed, which have enriched and improved the fracturing and acidizing theory and formed four series of "key technologies for fracturing and acidizing reconstruction of special complex oil and gas reservoirs" with independent intellectual property rights, which have reached the international advanced level in general.

Independently innovated a number of key technologies, and formed a series of fracturing and acidizing technologies for ultra-low permeability and ultra-low permeability oil and gas reservoirs, which solved the problems of low single well production, rapid decline rate and great production difficulty, and played a leading role in the development of ultra-low permeability and ultra-low permeability oil and gas reservoirs in China.

Innovative research and development of ultra-high temperature and low-cost guar gum fracturing fluid system, forming ultra-high temperature and ultra-high temperature deep reservoir fracturing technology and construction decompression technology, solving the problems of low efficiency, high cost and high risk of ultra-high temperature fracturing, laying a material foundation for fracturing and acidizing reconstruction of ultra-high temperature/deep and ultra-deep reservoirs in China and providing alternative technologies.

For the first time, the method and device for measuring the depth of proppant embedded in rock stratum were invented, and the fracturing technology with high conductivity for sandstone-mudstone/gravel reservoir and the whole fracturing technology for complex fault-block reservoir were formed, which explored a new technical direction for solving the long-term problem of how to further improve the development effect and oil recovery of low-permeability old oil fields.

A series of basic problems derived from the development of wormholes in fractured-vuggy reservoirs are creatively solved, and a series of acid fracturing technologies for fractured-vuggy carbonate reservoirs are formed, which provide core technologies for exploration and evaluation, productivity construction and efficient development of this special type of reservoirs.

The achievements have been authorized for invention patents 15, utility model patents 1 1, software copyrights 4, industry standards 2, enterprise standards 8, and international papers 1 12 published by SCI and EI. We trained 34 doctoral students and 25 master students/kloc-0, held 7 training sessions on new technologies, and trained a large number of fracturing and acidizing technicians. This achievement has been applied in Changqing, Northwest, Southwest, North China, Shengli, Xinjiang, Yumen, Qinghai, Jianghan, Daqing and other oil and gas fields of PetroChina and Sinopec. In the past three years, the output of crude oil has increased by 639 1 10,000 tons, and the output of natural gas has increased by126.67 million cubic meters, which has ensured the effective production and efficient development of a large number of special types of complex oil and gas reservoirs and produced very remarkable economic and social benefits.
