胡五块目前存在问题是:(1)水驱动用程度低,油田稳产基础薄弱,区块低效开发;(2)主力区块经多年注水开发和多轮次增产措施后开发难度进一步加大,油田产量递减严重,急需研究完善油田挖潜新工艺;(3)新探明储量大幅度减少,新动用的储量品位低,部分区块原油物性差,“双低”井的生产管理难度大,常规挖潜措施投入高、效益差,难以满足开发生产需要。微生物调驱技术是一项有效的层内挖潜技术。
The existing problems of Wu five are as follows: (1) The degree of water-driven use is low, and the foundation of stable oil production is weak and the blocks are inefficiently developed. (2) The development difficulty of main blocks after further years of water injection development and multiple rounds of stimulation measures is further increased (3) The new proven reserves have been greatly reduced, the reserves newly used are of low grade, the physical properties of crude oil in some blocks are poor, and the difficulty of production management of “double low” wells Large and conventional measures to tap the potential of high investment, poor efficiency, difficult to meet the development and production needs. Microbial regulation and control technology is an effective in-depth tapping technology.
