摘要
针对铜庄断块储层微裂缝发育 ,注入水单层、单向突进明显 ,水驱效率低等问题 ,通过采用高强度延迟交联部分水解聚丙烯酰胺 /酚醛体系对注水井进行深度调剖 ,从而调整纵向吸水剖面。通过室内实验优选了调剖剂配方 ,对单井进行了调剖优化设计 ,实施后取得了较好的开发效果。
In accordance with the problem that micro fracture developed in Tongzhuang fault block, injected water breakthrough in single layer and single direction, and low waterflooding efficiency, the vertical injection profile is adjusted through deep profile control by using high strength, delayed crosslinking, partial hydrolysis, polyacrylamide/phenolaldehyde system. The formula of profile control agent is optimized through laboratory experiment. Optimum profile control is designed for single well and has achieved good response after implementing.
