摘要
针对砾岩油藏开发中存在内幕及连通性不清的主要问题,进行了储层精细划分与对比、储层的沉积特征及空间展布特征、地应力测试、干扰试井、储层敏感性评价实验等研究。在此基础上进行了注水先导实验,并编制注水开发方案,实施全面注水,收到了良好的效果,为该类油藏的开发提供了宝贵经验。
Five researches,discussed in this paper,have been done in the study area:research on the elaborate division and correlation of the strata,the sedimentary characteristics of the reservoir and it's distribution,test of the terrestrial stress,interference well-testing,the experiment on the evaluation of the reservoir sensitivity.Based on the previous researches,a water-flooding-dredging experiment has been performed; full-scale water-flooding work has been done according to the water-flooding exploitation schedule,and the effect is fairly nice,which offer a good example for the exploitation of this kind reservoir.
