摘　　要：中国大陆及陆架位于欧亚板块东南部,处于西伯利亚板块、太平洋板块和印度洋板块的交汇区,由多块体、多山系和多盆地拼合而成,具有多旋回、多期次、海相和陆相都很丰富的油气生成和聚集过程。经过60多年勘探开发,目前国内油气田已形成年产原油2×108t、年产天然气1 000×108m3的生产水平。依靠现代地球物理探测,水平井、丛式井钻井,多段压裂、酸化增产技术,注水、注CO2等提高采收率技术,在四川、鄂尔多斯、松辽、渤海湾、塔里木和准噶尔等盆地逐步形成"立体勘探"的理论与实践。南方地区各盆地的古生界海相页岩有可能成为页岩气勘探的新领域,具较大的资源潜力。The China's Mainland and its shelf located in southeastern Eurasian plate is at the intersection area of Siberia plate, Pacific plate and the Indian Ocean plate, and split into the blocks, many mountains and more basins, with the processes of oil and gas generation and ac- cumulation of muhicycle, multistage, marine and terrestrial facies. Through 60 years of exploration and development, the current domestic oil and gas fields have formed the scales or levels of annual output of crude oil of 2× 10^8 t, annual output of natural gas production of 1000× 10^8 m3. Relying on modern geophysical prospecting, drilling horizontal wells and cluster wells, multi-section fracturing and acid stimulation technologies as well as EOR techniques such as waterflood, CO2 injection, etc., in Sichuan basin, Ordos basin, Songliao basin, Bohai Bay ba- sin, Tarim basin and Junggar basin have gradually created the theory and practices of ＂three-dimensional exploration＂. In many basins of South China, the Paleozoic marine shale may become the new domains for shale gas exploration and have large resource potentials.
