中国石炭—二叠系致密岩油气资源潜力分析

Analysis of Petroleum Resource Potentials in Carboniferous-Permian Dense Rocks of China

自1989年鄂尔多斯盆地靖边石炭系致密砂岩大气田发现开始,中国致密岩油气已有20多年的勘探历史。近年来,在鄂尔多斯、四川、准噶尔和塔里木等盆地中的志留系、石炭—二叠系、三叠系和白垩系等层位发现了致密砂岩油气田,进一步证明中国致密岩油气潜力巨大。研究认为,石炭—二叠系致密岩油气前景最大,从原型盆地沉积体系和含油气体系等方面,论述了其含油气前景和勘探方向。

Since the discovery of a large gas field in Jingbian Carboniferous tight sandstone of Ordos basin in 1989, China＇ s tight rocks exploration for petroleum has a history for more than 20 years. In recent years, many tight sandstone oil and gas fields have been found in Silurian, Carboniferous-Permian, Triassic and Cretaceous in Ordos, Sichuan, Junggar and Tarim basins, further proving that China＇ s petroleum potentials in tight rocks are great. The study suggests that, of the so many strata, the Carboniferous-Permian tight rocks oil-gas exploration prospects are the largest. Also, this paper presents and discusses the oil-gas prospects and targets from the prototype basins＇ sedimentary systems and petroleum systems.
