摘　　要：我国大部分油田现己进入开发中后期,如何根据油田自身的动态变换规律确定合理的开发方案,是油田亟待解决的关键问题之一。引入一种新的评价模型——非线性模糊综合评价模型,该模型通过特殊影响因子的引入解决了传统的线性加权模型所忽略的问题,即特殊影响因素(如动态回收期)对评价结果的影响,从而全面地考虑了影响油田开发规划的各种技术、经济指标在整个方案优劣评价中的重要程度,进而得到油田开发方案优化排序。In China,the most of oilfields were at the middle and late stage of development,how to determine a rational development program according to their dynamic changing rules was one of the critical problems needed to solve badly.A new evaluation model——nonlinear fuzzy comprehensive evaluation model was introduced to solve the ignored problem of impact factors,which could not be solved by using traditional method.The model introduces prominent impact factors to overcome the problem-the influences of prominent impact factors to the evaluation result,which neglects by linear weighted model.It comprehensively analyzes the influence of development and economical factors on development program,constructs a comparative evaluation factor system of oilfield development program and obtains the optimal order of the programs.
