欢26(东)块兴隆台油层目前处于特高含水开发阶段,区块开采水平逐渐下降,不能达到水驱标定采收率;水驱波及体积难以持续扩大,注水无效循环严重;剩余油分布高度零散,具有针对性的有效挖潜手段优选难。通过对开发区块进行流动单元划分,有针对性的对各个流动单元进行潜力研究,寻找挖潜潜力点,有效的提高区块产量,提升采收率。
Huanrong 26 (East) Block Xinglongtai oil reservoir is currently in the ultra-high water-cut development stage, the block mining level gradually decreased, can not reach the waterflood calibration recovery rate; water-driven volume and difficult to continue to expand, water injection ineffective cycle serious; remaining oil distribution height Fragmented, targeted and effective means to tap potential optimization difficult. Through the division of flow units in development blocks, the potential study of each flow unit can be targeted to find the potential for potential tapping, effectively increase the output of blocks and enhance the recovery rate.
