摘要:

以室内实验和数值模拟研究为基础,根据葡北地区矿场试验情况,从调剖井调剖目的层、非目的层吸液剖面以及试验区生产动态等方面的变化,对交联聚合物(CD剂)深度调剖时提高采收率的作用进行了较为深入的分析。结果表明,对于砂体以水下分流河道沉积为主、砂体多呈条带状,且水驱方向较为单一的油田,在高含水期,首先时高含水厚油层进行深度调剖,然后时全井进行后续水驱,能够有效降低含水,增加产油量,是提高采收率的有效措施。

Abstract: Based on lab tests, numerical analog and field tests in Pubei area,the effect of crosslinked polymer depth profile control on IOR has been analyzed in this paper in respect to the change of target bed of profile control in profile control well,fluid entry profile of non-target bed and production performance of the test area. The results show that depth profile control should firstly operated in high water cut thick oil zones for the field with the sand body mainly being underwater distributary channel sand and being stripped like, and with water driving direction being fairly single. And then the successive water flood can be performed to the whole well. This is effective to improve the development of oil filed at high water cut stage. The method is important for lOR and has a potential to be widely used.

Key words: crosslinked polymer, depth profile control, effect analysis, recovery factor
