摘要: 塔中地区下奥陶统鹰山组碳酸盐岩储集层由于受到断裂活动的影响而发生了一系列的变化,其主要体现在3 个方面:断裂附近的储集层中形成了与断裂活动相关的裂缝,产生了一个高孔-渗带,多级次、多方位裂缝的发育与沟通使得碳酸盐岩的储集性能得以改善;断裂及其所产生的裂缝可作为深部流体的运移通道,由此储集层中大多发生了溶蚀作用、交代作用和白云岩化作用等建设性的改造作用;近地表断裂活动沟通地表水,使岩溶作用深度加大,导致溶蚀和裂缝的发育深度增加,有效储集空间增大。

Abstract: A series of physical and chemical changes took place by the fault activity for Yingshan carbonate reservoir of the Lower Ordovician in Tazhong area. They are the fractures related to the faulting formed in the reservoir near the faults, a high porositypermeability zone, multistage and multi-orientation fractures that improve the carbonate reservoir quality; the fractures as channels for deep fluid migration and various modification processes like solution, metasomatosis and dolomitization; the near-surface fault activity that connected with surface water, deepened the depth of karst, solution and fracture development, thus increasing the effective reservoir spaces.

Key words: Tarim basin, Lower Ordovician, Yingshan formation, carbonate rock, fault activity
