摘要
海拉尔油田兴安岭储层属于特低渗透油藏,且水敏指数较高,常规注水开发效果很差。针对兴安岭储层这一特点,通过室内实验,优选试验区、优化油藏开发方案和跟踪动态分析,研究特低渗透强水敏储层CO2驱油开发的可行性。目前兴安岭储层CO2驱油已取得了矿场试验阶段成果,为加快海拉尔油田上产提供了技术支撑。
Xing＇anling reservoir of the Hailar oilfield belonging to the Ultra-low permeability reservoirs, and water sensitivity index was higher, and the effect of conventional waterflood development was poor. For Xing＇anling reservoir characteristics researched the feasibility of COz flooding for the ultra-low permeability of strong water sensitivity reservoir through laboratory experiments, the preferred test area, optimize reservoir development programs and tracking of dynamic analysis. CO2 flooding of Xing＇anling reservoir is made in the initial results of the field tests, and provided technical support to speed up the the Hailar oilfield production.
