混合液电阻率(R_z)是指冲洗带中泥浆滤液和原生水混合后的液体的电阻率。德莱赛·阿特拉斯公司提供的图板很难用于实际测井解释,原因是不易确定混合系数(Z)。在侧向测井系列资料的解释中,用比值法求地层含水饱和度效果较好。因为当用R_t/R_x。作为一个参数时,地层因素(F)的影响可以消除,泥质的影响也可以得到部分消除;当用R_(mf)/R_w作为一个参数时,又可以在未知R_w的情况下求解地层含水饱和度。后者更为
Resistivity (R_z) of the mixture refers to the resistivity of the liquid mixed with the mud filtrate and the raw water in the rinse zone. The charts provided by Dresdner Atlas are difficult to interpret in actual logs because the mixing factor (Z) is not easy to determine. In the interpretation of the series of lateral logging data, it is better to use the ratio method to find the water saturation of the formation. Because when using R_t / R_x. As a parameter, the influence of formation factor (F) can be eliminated and the influence of shale can be partly eliminated. When R mf / R_w is used as a parameter, the saturation of formation can be solved without R_w degree. The latter is more
