高含水期油田提高采收率方法

提高油藏采收是油田开发工作的最终目的。从临盘油田油藏地质特征出发，在分析开发生产中存在问题及查清剩余油分布的基础上，通过现场各种调整挖潜措施的实施，使大芦家，盘2－14断块的开发状况变好，采收率分别提高6．67％和14．8％。因此，水平井，不稳定注水及调堵技术是监盘油田高含水期提高采收率行之有效的方法。对类似的高含水期注水开发小断块油田提高采收率有重要意义。

EOR for the oilfields in high water cut period

Enhancing oil recovery of oil reservoirs is the final goal for the oilfield deve lopment. According to the geological properties of the oil reservoirs in Linpan oilfield and based on the analysis of the problems appeared in the production an d to make the remaining oil distribution clear, various measures for tapping the potential in the field are adopted and the development status in Dalujia and Pa n 2-14 fault blocks are better with 6.67% and 14.8% of the improved recovery fa ctor, respectively. So horizontal wells, unstable water injection and profile control -plugging are the effective methods for EOR in the oilfield in high water cut p e riod. It is of significance on EOR for the similar small fault block oilfields b y waterflooding in the high water cut period.
