高含水油田开发效果评价方法分析

Analysis of Evaluation Methods for Development Effect of High Water Cut Oilfields

本文以某油田开发区过渡带的开发效果为例,展开评价,依据现实开发状况,构建评价指标体系,借助于层次分析法,对各个参数的权向量加以明确,以此来对灰色关联分析法与加权平均法无法弥补明确权向量方面的不足进行弥补;除了对水驱开发效果进行评价外,还以人为控制因素为对象,对其开展多级模糊评判,以此使最终评价效果变得更为实用、科学与公正。

Taking the development effect of the transitional zone in an oilfield development zone as an example, this paper conducts evaluation, constructs an evaluation index system according to the actual development situation, and clarifies the weight vectors of various parameters by means of analytic hierarchy process, so as to make up for the deficiency that gray correlation analysis and weighted average method can＇t make up for of weight vectors. In addition to evaluating the water drive development effect, it also takes human control factors as the object, and carries out multi-level fuzzy evaluation on it, so as to make the final evaluation effect more practical, scientific and impartial.
