摘要
针对不同储层的渗流特征以及压裂裂缝扩展规律,探讨油井控水压裂技术实施效果。分别通过选择性控水支撑剂、透油阻水压裂液、人工隔离层等工艺进行现场先导实验,观察分析控水工艺使用前后含水率与产油量的情况。根据不同高含水井区的工程地质特征,提出控水压裂工艺优化选择方案。
According to the different reservoir flow characteristics and fracture extension, this paper discusses theeffect of water selected control wells fracturing techniques. Respectively, from the use of selective control of waterproppant, water blocking fracturing fluid and manufacturing artificial isolation layer three processes on - site pilottest application effect analysis, it can analyze the processes controlling water and moisture content before and afteruse oil production situation. Combined with the engineering geological characteristics of different zones with highcontent of water wells, a optimization fracturing process selection is proposed.
