欢127东块自1989年投入开发,2007年区块二次开发,到2010年底二次开发已进入快速递减阶段。为减缓产量递减,2011年底重新落实了断层构造,在北部断层区域部署4口新井,取得一定效果,综合分析下步将采取组合注汽、防砂及工艺降粘等措施提高新井产量,改善区块开发效果。
Huan 127 East block since 1989 into development, block secondary development in 2007, by the end of 2010 the second development has entered a rapid decline phase. In order to slow down the production decline, the fault structure was re-implemented in the end of 2011 and four new wells were deployed in the northern fault area with some results. A combination of steam injection, sand control and process viscosity reduction will be taken to improve the production of new wells and improve the block Development effect.
