production layer

Re-utilization of production layers can be carried out when the residual oil potentials near wellbores can not be economi-cally and effectively recovered with conventional measures such as supplementary perforation,fracturing,acidization and water plugging.

油田进入高含水开发后期,剩余油潜力主要分布在流动单元内部及其间的岩性段中,具有“薄、散、小、差、低”的特征,当采用常规的补孔、卡封、压裂、酸化、堵水等措施不能再经济有效地挖掘井筒周围的剩余油潜力之后,接下来可考虑开采层的重复利用。
