摘要
影响重复压裂选井的因素很多,各因素之间关系复杂且存在一定的模糊性。本文中,采用模糊综合评判方法,全面考虑了影响重复压裂效果的多种因素,求解了重复压裂过程中的选井问题,对于各影响因素给出了权重的计算方法,建立了相应的模糊模型和求解方法,可对重复压裂候选井按从优到劣进行排序,定量判断合适的候选井。经矿场实例验证该方法具有较高的可靠性,对重复压裂选井具有重要的指导意义。
There are many factors that affecting refractured well selection and the relationships ot them are complex existing certain fuzziness. In this paper, adopting fuzzy method of synthetical appraisement and considering the effects of several factors, well selection of refracturing has been deal with. To be dead against multi--effect of kinds of factors, weighted method is recommenced and a fuzzy model and corresponding solving method are presented. By that we can quantificationally determine the preferred candidate well for refracturing and from the field study, it is proven to be of great reliability and of significance for well selection during refracturing treatment.
