| 摘 要： | 下奥陶统碳酸盐岩是阿克库勒地区主要含油气层,岩溶作用是影响奥陶系储层发育的最主要因素。本文详细论述了该区下奥陶统发育多期岩溶,海西早期是主岩溶期,该期岩溶主要形成于表生大气淡水条件下,岩溶作用深度和范围受志留-泥盆系和上奥陶统隔水层限制。指出岩溶斜坡区的地表岩溶带及潜流岩溶带上部是有利的储层发育和油气主要富集区带。

| Abstract: | Lower Ordovician carbonate rock is the major reservoir in Akekule area of Tarim Basin, and karst is the most important factor influencing Ordovician reservoir. The authors point out that karst in the study area is paleo supergene karst mainly controlled by fresh water karst and with multi stage features. The development depth is restricted by waterproof stratum of Silurian Devonian and Upper Ordovician rocks. We also suppose out that the surface of karst zone and upper phreatic karst zone in karst slope unit is favorable reservoir and enrichment region of oil and gas. |
