四川盆地海相碳酸盐岩储集层与构造运动的关系

The Relationship Between Marine Carbonate Reservoir and Tectonics in Sichuan Basin

储集层是四川叠合盆地海相碳酸盐岩油气成藏的关键因素之一,海相碳酸盐岩储集层的发育主要受升降运动和地裂(伸展)运动的控制。升降运动形成的古隆起形成不整合面控制碳酸盐岩岩溶型储集层;地裂运动的台块-台槽(拗拉槽)格局造成强烈的沉积相的分异,控制着礁滩的空间分布、溶蚀作用、白云石化等,进而控制海相碳酸盐岩储集层的发育。

Reservoir is one of key factors of hydrocarbon accumulation of marine carbonate reservoir in Siehuan superimposed sedimentary basin. The marine earbonate reservoir is controlled by the lifting and rifting movements, of which the karst reservoir is controlled by the unconformities formed by the uplifts in the lifting movement; the reef flat reservoir is controlled by the sedimentary faeies differentiation resulted from platform block-trouph framework, including the reservoir distribution, dissolution, dolomitization, etc. in the rifting movement.
