DST测试资料在二连油田阿南油藏重复压裂设计中的研究与应用

DST Data Research and Application of Anan Reservoir of Erlian Oil Field in Refracturing Designs

由二连油田阿南油藏12口井的DST测试资料，应用模糊设计原理，研究了储层有效渗透率与电测渗透率、储层压力系数、电测孔隙度、含水率、上覆层压力以及最小水平主应力间的关系。该方法考虑的因素较为全面，并且在权重的确定上，巧妙地引用了灰色关联度法，克服了以往机重确定方法上的不足，使之更具量化标准。经实例验证，与油藏数值模拟得出的有效渗透率，基本吻合。

According to the DST data of twelve wells in Anan reservoir of Erlian oil field, relations between formationeffective permeability and electric log permeability, formtion pressure coefficient, electric log porosity, watercut, overlying pressure and minimum horizontal stress are investigated by using the fuzzy design principle.Particularly, more influence factors are considered in this research. The weight determination with morequantitative criterion was improved further by using the methed of gray correlation index to exclude somedeficiency in old techniques. Approximately, the formation permeability obtained in this study is in conformitywith simulation results.
