塔里木盆地轮古西地区岩溶缝洞型储层井间连通性分析——以LG15-A井组为例

摘要

塔里木盆地轮古西地区奥陶系碳酸盐岩属于岩溶缝洞型储层,非均质性强,油水关系复杂,空间连通性差,现已进入开发注水阶段.通过静、动态综合分析的方法研究油藏连通性,认为LG15-A井组为一连通单元.同时指出三维缝洞雕刻技术是油藏评价及开采的有效技术,可为单元的连通性研究提供很好的静态证据.%Karst fracture-cavity reservoir of Ordovician carbonate rocks in west Lungu region, Tarim Basin, has very violent heterogeneity. The relationship of oil and water is complex. The connectivity is poor. Now the reservoir lies the flooding stage of development phase. Combine the static connectivity method with dynamic one to analyze the interwell connectivity, the result shows that well LG15-A is connected with well LG15-B. And the 3D fissure & carving description technology is the effective method to evaluate the reservoirs. And it is the good static proof of analyzing the connectivity.
