摘要

塔河油田属于碳酸盐岩岩溶缝洞型底水油藏,水体较活跃,储层非均质性强,前期油田递减率一直在25%以上,通过对油藏递减因素进行分类分析,从地质、油藏、采油工艺各个环节入手,找准影响递减主要因素,采取针对性的控制递减措施,对油田递减实施全过程、全方位的控制,逐年降低油田递减率,提高油田开发效果。

Abstract

Reservoirs in the Tahe Oil Field are carbonate karst ones with active bottom water and strongheterogeneity.In the past years,oil field descent rate was over 25%.Reasons for the descent were clas-sified.From the aspects of geology,accumulation and oil recovery process,the main factor for the de-scent was found.Descent control considering different factors was carried out,reducing descent rate andimproving oil field exploration effect.
