摘　　要：对二连油田乌里亚斯太地区的23口开发井和探井的地质参数、生产动态参数、压裂施工参数以及它们的压裂效果进行了统计和分析。根据模糊识别理论,建立了各影响因素与压裂效果之间的模糊关系。压裂候选井的选择,最终可以通过欧氏贴近度的大小进行定量判断。通过对施工参数的敏感性分析,可以优选出最佳的施工参数。应用建立的模型,对该地区的几口未知样品井进行了预测,其预测效果与实际情况具有很好的吻合性,表明该方法进行压裂选井选层是可行的。Statistics and analysis are conducted for the geologic parameters,the production performance parameters,the fracturing parameters and the fracturing results of 23 development and exploration wells in Wuliyashitai area.Based on the fuzzy diagnosis theory,the fuzzy relation between the effecting factors and the fracturing results is set up.According to the value of Owen's fitting level,the quantitative judgment can be conducted to determine the candidate fracturing wells.By analysis of sensitivity against the fracturing parameters,the optical fracturing parameters can be selected.With the established model,some unknown wells are predicted in the area.The predicted results are coincident with the real situation very well,which proves it is feasible to apply the method to optimize fracturing wells and formations.
