| 摘 要： | 空隙是构成碳酸盐岩储层的基本单元，空隙发育史对应了成岩演化史，且不同类型空隙的储层具有不同的分布规律。塔里木盆地塔中地区奥陶系碳酸盐岩储层的空隙可以分为６类２１种，以裂缝—孔洞型为主，礁、丘、滩相碳酸盐岩、中—细晶白云岩与古岩溶和构造岩溶的复合区为有利空隙发育带，也是风化壳型油气藏和内幕型油气藏的有利储集相带。

| Abstract: | Void is the basic unit in carbonate reservoir. It's developing history corresponds diagenetic evolution. A reservoir with different void has it's own distribution regularity. The void in Ordovician carbonate reservoir from Tazhong area, Talimu(Tarim) Basin can be divided into 6 kinds and subdivided into 21 groups. The fractured/vuggy carbonate is the main type of reservoir in the area. The reef, mound and beach carbonate, particularly, medium to fine crystallized dolomite combined with paleo karst and structural solution are always expected to be favorate targets of weathered crust or inner formation reservoirs. |
