裂缝性储层屏蔽暂堵技术与解堵技术研究
Research on the Shielding Temporary Plugging and Blockage Removing in Fractured Reservoir

摘要: 根据对碳酸盐岩储层岩性、物性和敏感性的分析,室内优化了保护裂缝性碳酸盐岩储层的钻井完井液的性能参数,并对碳酸盐岩储层的水锁效应及应力敏感性进行了评价。并且对封堵的地层进行成功的解堵。所以对裂缝性油藏暂堵并不是关键,关键是成功的封堵之后成功的解堵。Abstract: Through analysis of lithology, physical characteristics and sensitivity of carbonate reservoir, drilling/completion fluids for protecting fractured carbonate rock reservoir were developed. Water locking and stress sensitivity of carbonate reservoir were evaluated and used to remove blockage of temporary plug-ging reservoir successfully,so the key point is how to remove the temporary plugging successfully.
