边远难采油田吨油成本居高不下,迫切需要建立一套适合难采油田的措施效果评价体系,本文通过对影响油井措施效果的诸多因素进行分析,综合利用了模糊综合评价法、灰色关联法和综合效益评价法这三种方法结合对措施效果进行评价,建立了南翼山油田III+IV油层组措施效果评价体系,通过预测可以优选南翼山油田III+IV油层组压裂改造措施的井和层位,达到提高单井产量,提高采收率,达到经济效益开发的目的。
It is urgent to set up a set of evaluation system of measures for the effect of oil-deprived oil fields. By analyzing many factors that affect the effectiveness of oil well measures, the paper makes comprehensive use of fuzzy comprehensive evaluation method, gray correlation method And comprehensive benefit evaluation method to evaluate the effect of the measures, the evaluation system of the effect of III + IV reservoir formation in Nanyishan oilfield is established, and through the prediction, it is possible to optimize the fracturing improvement measures of III + IV reservoir in Nanyishan oilfield Wells and layers, to improve single-well production, increase oil recovery, to achieve the purpose of economic development.
