碳酸盐岩储层具有异常复杂的非均质性,碳酸盐岩岩溶作用研究是当今储层沉积学和储层地球化学研究的重要前缘领域.塔河油田所处的阿克库勒凸起是在前震旦系变质岩基底上长期发育的一个古隆起,经历了加里东期和海西期多期次的构造抬升和海平面变化影响,并受到后期构造运动的叠加改造,发育了一套寒武-奥陶系碳酸盐岩岩溶-缝洞型储层.结合塔河油田岩溶作用的基本特点和勘探实践,建立了奥陶系碳酸盐岩储层岩溶作用的3种基本模式,并分析了岩溶发育的主要控制因素.

Karstification research of a complicated anisotrophic carbonate reservoir is presently an important leading field for reservoir sedimenology and geochemistry. Akekule convex included Tahe Oilfield is a long-term developed paleo-uplift based on the pre-Sinian metamorphic basement, which affected by multi-period of Caledonian and Hercynian tectonic uplift and sea-level changes, and superposing reformed by late tectonic movement. A set of Cambrian-Ordovician carbonate karst-fracture-hole reservoirs were developed in Akekule convex. Combined with the karstification and exploration in Tahe Oilfield, three karstification models were established in the area and the key controling factors of karst development were analyzed.
