The integration of oil and gas geology and engineering has become a trend

At the 2022 International Conference on Oil and Gas Field Exploration and Development with the theme of "Integration of Geology and Engineering to Improve the Efficiency of Complex Oil and Gas Reservoir Exploration and Development" on November 16~18, the integration of oil and gas geology and engineering and intelligence to promote efficient exploration and development of oil and gas fields have become a hot topic
for experts and scholars attending the meeting.

"The oil and gas industry is accelerating the integration of geology and engineering, digitalization and intelligent development, and large enterprises are strongly promoting strategies and action plans, but from the overall trend of technological development, both domestic and foreign are in their infancy
.
" Li Gensheng, academician of the Chinese Academy of Engineering and director of the State Key Laboratory of Oil and Gas Resources and Exploration of China University of Petroleum (Beijing), said that it is necessary to accelerate the strategic layout and research efforts, take geological and engineering big data as the core, integrate oil and gas intelligent equipment and artificial intelligence algorithms, and realize the whole life cycle of oil and gas exploration and development through
data governance and iterative circulation, oil and gas artificial intelligence scenarios, and digital twin visualization platform.

Li Gensheng believes that the deep integration of artificial intelligence and oil and gas exploration and development is the key to
realizing the intelligence of oil and gas geology and engineering.
Their team has developed six intelligent scenarios + intelligent integrated management platform, including geological intelligent evaluation, reservoir intelligent exploration, oil and gas intelligent drilling, reservoir intelligent completion, oil and gas intelligent development and safety intelligent guarantee, integrate and establish an integrated management cloud platform based on big data and Internet of Things, rely on cloud computing and artificial intelligence methods, globally regulate operation parameters, monitor working conditions in real time, and realize intelligent digital twin and integrated management
of oil and gas geology and engineering throughout the life cycle.

According to reports, the platform's geological intelligent evaluation, reservoir intelligent detection, oil and gas intelligent drilling and reservoir intelligent completion system have been verified on site in oil and gas wells in Daqing Oilfield, Shengli Oilfield, Tarim Oilfield and Xinjiang Oilfield, and the production and recovery rate of single wells have been significantly improved
.
The intelligent drilling and completion system platform has been put into operation in Changqing Oilfield, and all have achieved good results
.

The reporter learned that the integrated application platform of oil and gas exploration and development geology and engineering information integrated application developed by the scientific research team of Professor Li Tiantai, president of Xi'an Shiyou University, has been applied in Changqing Oilfield, Nanhai Oilfield, Bohai Oilfield and other oilfields, with remarkable
results.

"This integrated platform is popularly speaking, it is the use of modern information and computing technology and geomechanical modeling methods to make the underground formation environment intuitively displayed in the form of data, which is equivalent to doing CT
for the underground operation environment.
" Li Tiantai said that through this platform, the real geological environment and mechanical parameters underground can be quickly provided for the construction of oil and gas exploration and development sites, so as to facilitate the timely adoption of more optimized and reasonable parameters in the process of drilling and completion and fracturing, and reduce engineering costs
.

According to Liu Xianyang, chief technical expert of PetroChina's Changqing Oilfield Branch, after applying the platform, they can avoid faults during fracturing design and transformation, so that oil and gas resources can be effectively used
.

Li Tiantai also said that to ensure national energy security and reduce the dependence of oil and gas on foreign countries, it is necessary to increase exploration and development and improve the independent supply capacity
of oil and gas.
Only with the continuous development and continuous progress of exploration and development technology, promoting technological innovation, enhancing the ability to participate in international oil and gas cooperation, and grasping the initiative of oil and gas energy security, can we effectively solve the problems
existing in China's oil and gas field exploration and development.
