摘要： 甘青截含油气区面积约269.5×104km2. 是我国面积最大的一个含油气区。在9个沉降带中分布若32个含油气盆地, 总面积达159×104km2. 它们都是长期发展的登合型含油气盆地, 圣合若中一上元古界、古生界、中生界和新生界多套海相、海陆交互相和陆相含油建造, 并具备了多期非生物油气源的地质一构造条件。因本区自然地理条件非常恶劣, 新构造运动十分强烈,以致目前其勘探程度很低, 勘探效果也不理想。从四个方面对其含油气性进行了评价.旨在引起间志们的争论和思考,以利于本区油气勘探事业的发展。

Abstract: Gansu-Qinghai-Tibet petroliferous region is the largest sub- province of China with an area of about 269.5×104km2. In its nine subsiding belts, there are 32 petroliferous basins with an area of 159xI0* km2 in total. They are basins with long-term devolution and superimposed by petroliferous multi-formations of marine, continental-oceanic and continental facies of Mid-Upper Proterozoic, Paleozoic, Mesozoic and Cenozoic, shaping the geologic structural conditions of multistage non-biologic sources. Since the natural geographic conditions in this region are abnormal atrocious, the neo-tectonic movement is very active, its petroleum exploratory extent is still low and the effects for prospecting are unsatisfactory nowadays. This paper highlights the evaluation of hydrocarbon-bearning property from several aspects aiming at getting instructive dispute and thinking at home for further development of petroleum exploration cause in this region.
