Discussion and Research Direction of Future Onshore Oil and Gas Exploration in China

As the most abundant field of conventional oil and gas, onshore petroliferous basins with medium and high exploration degrees in China still play the role of "ballast stone" for national energy security under the situation of "stabilizing oil and increasing gas" in the future. How to further explore the potential of mature exploration areas and expand the exploration field is a problem worthy of in-depth discussion. Based on the recent oil and gas exploration results and exploration development trends, the research shows that there are five major areas that are the most realistic directions for future onshore oil and gas exploration, including continental shale oil and gas, near source geological bodies represented by overthrust structures in the eastern oil-rich depression, deep coalbed methane in coal rich basins, large-scale strike-slip structural systems and geothermal resources. In addition, for the old oilfields in the east, it is an important direction to "develop oilfield into geothermal field". In the future exploration work, explorers should strengthen basic research, especially in the mature exploration areas in the east of China. It is urgent to strengthen the geological evaluation of the three new fields and find new resources replacement fields in the old areas. The practice shows that advanced and applicable geophysical exploration technology and engineering technology are the basic guarantee for oil and gas exploration discovery and breakthrough, and also the fundamental way to reduce the cost of oil and gas discovery. Efficient management and decision-making, taking the initiative to play a pioneering role in exploration and leading the integrated research are important ways to accelerate the promotion of resources strategy.
