摘　　要：张宇晓等．双河油田储层电阻率的影响因素分析和校正．测井技术，１９９５，１９（１）：３５～３９本文对储层电阻率进行系统误差校正。在此基础上，分析了地层水电阻率、钙质含量、泥质含量和粒度中值对储层电阻率的影响并进行了校正。通过校正消除了岩性、地层水电阻率和粒度中值对电阻率的影响，突出了含油性对电阻率的影响，为更准确地计算含油饱和度打下了基础。System error corrections for reservoir resistivities have been made first. Then,the effects of formation water resistivity,Calcium and shale content and mediumgrain size on reservoir resistivity are analysed. By means of the corrections, allthese effects have been removed so that oil effect on reservoir resistivity becomesclearer and oil saturation can be calculated accurately and easily.
