W13西油藏进入高含水期后,剩余油分布零散,认识难度大。综合运用多种技术手段,提高剩余油认识,找准剩余油分布规律,是改善油藏后期调整挖潜的基础。因此迫切需要对目前已高含水开发期的W13西油藏加大剩余油监测技术的研究,应用目前先进、适应于此类油藏特点的剩余油监测技术进行测试,进一步深化和了解分类储层剩余油分布,以此作为下步精细注采调整挖潜的依据,进一步提高油藏采收率。
W13 West reservoir into the high water cut period, the residual oil scattered, difficult to recognize. Comprehensive use of a variety of technical means to raise awareness of remaining oil, identify the remaining oil distribution law is to improve the potential of late reservoir adjustment tapping potential. Therefore, there is an urgent need to research on increasing monitoring technology of residual oil in West W13 reservoir, which is currently in high water cut development stage. The remaining oil monitoring techniques that are advanced and adapted to the characteristics of such reservoirs are tested to further deepen and understand the classification of reservoir The remaining oil distribution, as the next fine injection and adjustment to tap the potential basis to further enhance the recovery rate of oil.
