摘　　要：在分析吴起地区长6油层组岩心试验资料、测井资料及试油资料的基础上,针对其高自然伽马不能精确计算泥质体积分数的难题,以测井响应特征分析为手段,提出了利用电阻率幅度差求取高自然伽马储层泥质体积分数的方法,编制了相应的程序,并进行了实际应用,效果良好。Based on the analysis of core testing data,well logging data and oil testing data of Chang 6 reservoir in Wuqi Area and in consideration of the problem of high natural gamma rate and the shale volume fraction not being calculated accurately,logging response characteristics were used for analysis.It is proposed that the difference of resistivity is used to calculate the shale volume fraction and create the corresponding program.The method is applied in practice and the result is satisfactory.
