普通电阻率测井解释储层参数的方法及应用

Reservoir Parameter Interpretation with Conventional Electric Resistivity Logging and Its Application

针对克拉玛依油田克下组储层,首次开展了四性关系研究,建立了普通电阻率测井解释模型。克下组储层发育一套砂砾岩沉积,其测井资料中有部分井无声波测井曲线,而只有电阻率测井曲线。因此,通过对岩心分析资料与各种测井值相关性研究确定采用电阻率计算有效孔隙度、渗透率的方法,利用“岩心刻度测井”技术建立了电阻率测井解释模型,所建立的测井解释模型的计算精度能够满足油田开发需要。

Four properties(lithology,physical property,oil property and electrical property) to Kexia formation in Kelamayi oilfield have been analyzed at first,to establish conventional resistivity logging interpretation model.There is a series of glutenite sediment developed in Kexia formation. To some wells,there is no acoustic log curve,but only resistivity log curve.Therefore,resistivity calculation method is determined to calculate effective porosity and permeability,according to core analysis and various log value correlation.Electric resistivity logging interpretation model,established with 'core scale logging' technique,has a higher calculating precision,and is suitable for oilfield development.
