油田经过聚驱开发后,油层动用程度得到了较大的改善,但聚驱后仍存在一部分剩余油。为了寻求后续水驱阶段剩余油切实可行的有效挖潜方法,科研人员利用室内实验和数值模拟结果,明确不同类型剩余油分布,为后续的挖潜提供了较大的保障。另一方面,由于目前的能源面临一系列的危机,如果不能进行有效的挖潜,势必对其他领域的工作产生较为消极的影响。聚驱后剩余油挖潜及分布的相关技术,是目前的重要研究工作。
After the oilfield development by poly flooding, the utilization of the reservoir has been greatly improved, but there is still some residual oil after the flooding. In order to find out the feasible and effective method of tapping the remaining oil in the subsequent waterflooding stage, the researchers used the laboratory experiments and numerical simulation results to clarify the distribution of remaining oil of different types, which provided great protection for subsequent tapping. On the other hand, the current energy crisis is facing a series of crises. If we can not effectively tap the potential, it will inevitably have a more negative impact on the work in other fields. Related technologies of tapping potential and distribution of residual oil after poly-flooding are currently important research work.
