Abstract The application of Reservoir Saturation Tool (RST) well logging in horizontal production well or highly-deviated production well can help get continuous measured values of oil holdup, gas holdup and water holdup. The authors aim to probe into oil holdup acquisition methods through RST well logging,which can determine the well hole oil holdup based on model analysis of RST dual detector well logging. In the process of model inversion, the acquisition of sensitive coefficients for this tool is based on the random number analysis method, and thus more accurate sensitive coefficients are obtained. This process acquires well hole holdup by using model inversion on the basis of the combination of desired coefficient and other well logging data. A comparison of calculated values with measured values and an analysis of the errors of the results show that this method is feasible.
