高渗透稀油强边水驱油藏含水井开采对策

Production strategy of water breakthrough wells in high-permeability and light-oil reservoir with strong edge water drive

春光油田具有埋藏浅、高孔、高渗、稀油、边水活跃的特点,开采关键是用好边水。应用矿场生产资料、系统试井资料、同类型油藏类比、油藏工程方法、数值模拟方法、渗流力学理论建立了动态监测系统,采取油藏工程方法监控边水推进速度和水线推进状况,不断调整优化工作制度,对见水井排8-20、排8-C3井实施干灰堵水,取得好效果。春光油田2005年开发以来产量稳步上升,保持自喷开采,边水水线缓慢、均匀推进,采油速度、采收率同创新水平。

Chunguang Oilfield was shallowly buried,and a high-porosity,high-permeability,and light-oil reservoir with active edge water drive.Production key technology is how to use edge water.The dynamic monitoring system was built up by field production data,well testing data,similar reservoir analogy,reservoir engineering method,numerical simulation,and percolation theory.It was supervised by reservoir engineering method to the velocity of edge water movement and waterplane quantitative description,and the reasonable producing working system was continually adjusted.For water breakthrough wells,such as Pai 8-20,8-C 3 wells,water plugging gained good results.Since 2005,Chunguang Oilfield can make stead increation of oil production,keep nature flow,slowly move edge waterline,and achieve high production rate and oil recovery rate.
