聚驱后水驱试验区块经过聚驱开发后,油层动用程度得到了较大改善,随着聚驱开发时间的延长,注聚区块陆续进入后续水驱开发阶段,如何利用精细地质研究深入认识地下形势变化,进一步提高油层动用程度,是油田进入后续水驱阶段开发面临的重要问题。为了寻求切实可行的有效挖潜方法,综合运用精细地质研究及动态反映特征,明确了该区块现开发特点及矛盾,并开展挖潜方法研究,取得了较好效果,为后续水驱开发提供了可靠依据。
After the flooding test of poly flooding, the extent of reservoir utilization has been greatly improved after poly flooding. With the development of poly flooding, the flooding blocks gradually enter into the subsequent water flooding development stage. How to make use of the study of fine geology Understanding the changes in underground conditions and further increasing the utilization of oil layers is an important issue for the oilfields to enter the stage of subsequent water drive. In order to find a feasible and effective method of tapping the potential, comprehensively using the fine geology research and the dynamic reflection characteristics, the characteristics and contradictions of the development of the block are clarified and the potential tapping methods are studied. The results have achieved good results and provided reliable for subsequent water drive development in accordance with.
