摘要: 水淹层测井评价关键技术之一就是精确计算水淹层混合液电阻率,目前精确计算水淹层混合液电阻率的方法精度亟需提高。为此,本文提出精确计算地层混合液电阻率的微元动态物质平衡法。该方法将水驱油过程微元化,并考虑到水驱油过程中地层原生水与注入水离子有效交换比例这个变量,理论上该变量随水淹程度的增强从0逐渐变为1。对比结果表明,一阶导电法、变倍数物质平衡法和改进的微元动态物质平衡法模拟计算岩石电阻率的平均相对误差分别为0.192、0.169和0.124,改进的微元动态物质平衡法精度有了较大的提高,并且得到的混合液电阻率在不同水淹类型测井评价中可以更精确地计算剩余油饱和度。该方法已推广应用到各大油田不同水淹类型测井评价中,计算的水淹层含水饱和度与密闭取心的饱和度数据最为接近,水淹层测井综合解释符合率达到87%以上。
