摘要: 目前,我国已在松辽盆地、渤海湾地区、鄂尔多斯盆地和四川盆地的第三系、白垩系、侏罗系、三迭系和二迭系地层中在向斜发现了油、气藏。我国发现的向斜油、气藏有两种:(1)透镜体型和(2)裂缝型。透镜体型油藏发现在松辽盆地下白垩统姚家组和泉头组砂岩中,还有在渤海湾地区下第三系中、鄂尔多斯盆地的侏罗系砂岩中。裂缝型油、气藏发现在四川盆地三迭系和二迭系碳酸盐地层中。

Abstract: Synclinal oil and gas pools have been discovered in the Tertiary,Gretaceous, Jurassic,Triassic and Permian rocks in the Songliao,Bohai Bay,Ordos and Sichuan basins in China. They may be classified into two types: (1) lenticular type and (2) fissure type. Oil pools of the lenticular type are discovered in the Yaojia and Quantou sandstone formations of lower Cretaceous in the Songliao basin,in Eocene sandstones of Bohai Bay basin and in Jurassic sandstones of Ordos basin. Oil and gas pools of the fissure type are discovered in the Triassic and Permian carbonate rocks of Sichuan basin.
