柯柯亚致密砂岩气层评价方法研究

Research on Kekeya tight sandstone gas layer evaluation

根据柯柯亚地区储层岩石埋藏深,低孔、低渗,油气干层电性特征不明显的特点,利用岩心分析资料、岩电试验、矿物分析、压汞资料、相渗资料等,试油、录井资料结合常规测井方法和特殊测井新技术,采用曲线重叠法、测井交会图技术、交叉偶极子声波处理技术等多项测井测井技术和方法,建立了一套适合柯柯亚地区储层流体评价标准。

The layer rock Kekeya is deep buried with low porosity,low permeability and poor oil and gas electrical characteris-tics.In this paper,core data,rock-electricity test,mineral analysis,mercury injection data,relative permeability data,oil test,geology logging data have been used with conven-tional well logging method and special logging new technolo-gy.The author has applied various logging technologies and methods as curve over lapping,logging cross plot,crossed dipoles acoustic wave processing to establish a set of evalua-tion standard suitable for Kekeya formation fluid.
