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。
The reservoir is one of the key factors for hydrocarbon accumulation in marine carbonate rocks in the Sichuan superimposed basin. The development of marine carbonate reservoirs is mainly controlled by the ascending and descending movements. The paleo-uplift formed by the ascending and descending movements formed unconformity-controlled carbonate karst reservoirs. The pattern of the platform-platform groove (aulacogen) of the ground fissure caused a strong differentiation of sedimentary facies, controlling the reef Spatial distribution, dissolution, dolomitization, etc., to control the development of marine carbonate reservoirs.
