针对特高含水期油藏剩余油分布零散,开发潜力难以确定的问题,在统计典型油藏的油藏描述和数值模拟结果的基础上,运用层次分析法,对影响剩余油分布的主控因素进行层次划分和权重统计,建立特高含水期非均质油藏剩余油潜力定量预测模型,编制特高含水期非均质油藏潜力分布定量预测软件.利用该软件对坨21断块8层系的剩余油分布进行了预测,从而指导单元调整的方案编制和实施. Aiming at the problem that the distribution of remaining oil in the reservoir with extremely high water cut-off period is fragmented and the development potential is difficult to be determined, on the basis of statistics of reservoir description and numerical simulation of typical reservoirs, by using analytic hierarchy process, Level and weight statistics to establish the quantitative predictive model for the residual oil potential of the heterogeneous reservoirs in the ultra-high water-cut period and to prepare the quantitative prediction software for the potential distribution of the heterogeneous reservoirs in the ultra-high water-cut stage.Taking this software as an example, Department of the remaining oil distribution has been predicted to guide the unit to adjust the preparation and implementation of the program.
