The oil and gas industry in China has entered the stage of "simultaneous development of both shallow and deep sea areas, conventional and unconventional oil and gas, and onshore and offshore exploration", withonshore deep areas,deep sea areas,and unconventional oil and gas as important exploration priorities. Oil and gas engineering science and technology in China has seen 14 breakthroughs made in key areas and 6 key tasks to be completed in the fields of "onshore deep exploration, deep sea exploration, unconventional oil and gas exploration, recovery efficiency improvement and supporting engineering technologies". These developments will effectively promote the orderly succession of oil and gas exploration and the efficient use of oil and gas resources to achieve a sustained and healthy development of the oil and gas industry in China and boost the development and utilization of overseas resources.展开更多
