模糊数学理论在评价油田水驱开发潜力中的应用

Application of Fuzzy Mathematics Theory to the Evaluation of the Water Flooding Development Potential in the Oilfield

油田开发过程中要对其地质参数进行相应的评价,评价油田的相关地质参数有利于优化开发方式从而得到较好的开发效果。以模糊数学理论为基础,对影响某复杂断块油田水驱开发潜力的相关地质参数进行了综合评价,在综合分析研究的基础上给出了各个指标的评价标准,并通过层次分析法确定出了评价因素的权重,最后得出最终的评价结果,从而形成了一套完整的油田水驱开发潜力评价体系。通过某油田的开发实践证明,模糊综合评价方法科学、合理,在油田的水驱开发潜力评价方面应用效果较好。

In the course of oilfield development,the corresponding evaluation of geological parameters of the oilfield should be so proceeded that was favorable for optimizing the development,thereby getting better development results.Based on the fuzzy mathematics theory,the comprehensive evaluation of geological parameters affecting the potential of water flooding development in one complex fault block oil field was conducted.The evaluation criteria of each index were proposed on the basis of comprehensive analysis.The weight of evaluation factors was determined by AHP(Analytic Hierarchy Process),then the final evaluation results were obtained.At last,a complete set of potential evaluation system of the water flooding development formed.The application showed that the fuzzy comprehensive evaluation method was scientific and rational.
