摘要
针对油田开发中的不确定因素,结合油藏开发因素中的定性化指标,提出了一种基于油田开发水驱指标的模糊综合评价模型。通过灰色关联法定量筛选影响油田开发水驱因素的九项指标,运用层次分析法确定了各指标的权重,结合模糊数学中的判断矩阵实现了油田各区块的模糊综合评价。此方法不仅可以对所有区块进行总体评价,还能对各个具体区块进行精细的评价,为油田开发与管理提供了有效的指导。最后,通过实际例子验证了模型的有效性以及可行性。
According to the uncertain factors in the oilfield development, combining qualitative indexes of reservoir de- velopment, a new index evaluation model of oilfield development based on fuzzy theory is proposed. The nine indicators are established by using gray correlation method, and the weighting is obtained by using analytic hierarchy process. Finally, a fuzzy comprehensive evaluation is constructed based on judgment matrix in fuzzy mathematics. This method can not only as- sess all the blocks, but also evaluate certain blocks more precisely. It provides effective instruction for the development and management of the oilfield. The validity and feasibility of the model are demonstrated with the results of the practical exam- ples.
