断陷盆地碳酸盐岩潜山储层模式——以渤海湾盆地济阳坳陷为例

RESERVOIR MODEL OF CARBONATE BURIED-HILL IN RIFTED BASIN—TAKING THE JIYANG DEPRESSION AS AN EXAMPLE

摘要: 断陷盆地碳酸盐岩潜山发育了裂缝型、溶蚀型和孔洞型3种基本储层类型。不同的储层类型具有各自独立的成因机制和发育规律,它们共同构成风化壳淋滤带、垂直渗流带、水平溶蚀带、内幕孔洞带、断裂溶蚀带和构造裂缝带等6个储集体发育带,在空间上组合成复式立体的断陷盆地碳酸盐岩潜山储层模式。

Abstract: Carbonate buried-hill of rifted basin has 3 basic types of reservoir: fracture,corrosion and pore space.Each type has its specific forming mechanism and distribution rule.Various reservoirs assemble to form combinational solid reservoir model in space.It can be divided into weathered crust filtered belt,vertical seepage belt,horizontal corrosion belt,internal pore space belt,fracture corrosion belt and structural fracture belt.
