| description | The invention discloses an improved neutron lifetime logging interpretation model and a solving method of reservoir oil saturation based on the model. Monte Carlo simulation is adopted to qualitatively analyze the influences of oil saturation, formation water salinity, shale content and porosity on a formation capture cross section under the formation condition, wherein the shale content and the formation water salinity directly affects the differentiation of oil and water, so that the influences of the shale content and the formation water salinity are corrected according to the actual formation condition. Based on the traditional volume model and combining the Monte Carlo simulation with parameter sensitivity analysis, the invention proposes double-factor correction to correct the influences of shale and salinity (formation water), so as to increase the neutron lifetime logging interpretation accuracy.
