注水井调剖会影产油、产水、采收率、视吸水指数、经济效益等十多项指标。针对传统调剖评价方法只注重增油和降水两项指标的片面性和不确定性,本文使用模糊数学评价调剖效果,通过划分措施井为井组和区块,从水井、油井、油藏、经济四个方面的十项指标对措施井进行多级模糊评价,根据评价指数得出评价结果。该方法已成功应用于某油田29口调剖井及其对应的190口油井的评价,结果符合现场施工实际。
Water injection profile control shadow oil production, water production, recovery rate, depending on the water absorption index, more than 10 indicators of economic efficiency. In view of the fact that the traditional profile control evaluation method only focuses on the unilateralism and uncertainty of the two indicators of oil increase and precipitation, this paper uses fuzzy mathematics to evaluate the profile control effect. By dividing the measure well into well groups and blocks, Economic indicators of the four aspects of the four measures of multi-level fuzzy evaluation, according to the evaluation index derived evaluation results. This method has been successfully applied to the evaluation of 29 profile control wells and their corresponding 190 wells in a certain oilfield. The result is in line with the actual construction in the field.
