摘要
The mainland China 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 accumulation of multicycle,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 2×108t,annual output of natural gas production of 1 000×108m3. 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 basin,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.
