利用多层次模糊综合评判方法定量预测特高含水期油藏潜力

Determining the development potential of reservoirs at ultra-high water cut stage using comprehensive fuzzy analytical hierarchy evaluation method

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.

The scattered distribution of remaining oil and difficult to determine development potential are two major problems at ultra-high water cut stage. Aimed at the above-mentioned characteristics of reservoirs, on the basis of the statistics for the reservoir description and numerical simulation of typical reservoirs. Hierarchy division and weight analysis are carried out for the main factors influencing the distribution of remaining oil using AHP（Analytical Hierarchy Process） method. And the potential appraisal model of remaining oil for heterogeneous reservoir at high water cut stage is built . And then the appraisal sofeware of remaining oil for heterogeneous reservoir at high water cut stage is developed. The software is employed to successfully describe the remaining oil distribution in the same type reservoir of layer8 of block 21 in ShengTuo, providing guidance for scheming and implementation of unit adjustment. 21 block 8 laver.
