| 摘 要： | 麻黄山西探区大部分井的泥浆矿化度小于地层水矿化度,导致淡水泥浆侵入,影响电阻率测井值,使利用测井资料评价油水层存在较大的技术难度.在分析麻黄山西探区淡水泥浆侵入电阻率测井特征的基础上,对电阻率测井系列进行了合理选择,论述了径向电阻率比值法,并采用径向电阻率比值法计算含水饱和度,测井解释结果与试油资料对比表明,解释效果好,符合率高.

| Abstract: | The mud salinity is less than the formation water salinity in most wells of Mahuangshan’s west exploration area,causing the invasion of freshwater mud.As a result,the data of resistivity well logging is influenced,and evaluating oil and water layers by logging data is rather difficult in techniques.This paper analyzes the features of fresh water invaded resistivity well logging in Mahuangshan’s west exploration area,chooses the reasonable logging series,introduces the radial resistivity ration method,and uses the method to calculate the saturation.The comparison of logging interpretation result with the well testing data shows the interpretatino is effective and the coincidence rate is high. |
