RM反演是一种建立在模型基础上的波阻抗反演技术，它以测井资料为约束条件，以地震解释层位作控制，从井中声波、密度测井曲线求取声波阻抗曲线，选择与地震相匹配的低通滤波器，求取低频分量，然后由井旁地震道外推进行剖面上的反演。以此用于预测储尾砂体及地层岩性油藏的分布范围。
RM inversion is a wave impedance inversion technique based on the model. It takes the logging data as constraint condition and the seismic interpretation horizon as control. The acoustic impedance curve is obtained from the well acoustic wave and density logging curve. A low-pass filter matched to the earthquakes is used to extract the low-frequency components, which are then extrapolated from the seismic traces outside the well. This can be used to predict the distribution of reservoir tailings reservoirs and formation lithology reservoirs.
