Water holding rate imaging method for oil-water two-phase interface mixed stratified flow of horizontal well

The invention discloses a water holding rate imaging method during mixed stratified flow of an oil-water two-phase interface of a horizontal well, and relates to the technical field of dynamic monitoring of petroleum development, and the method comprises the following steps: S1, dividing the ranges of an oil phase, a water phase and an oil-water mixed phase; s2, reconstructing the water holding rate of an oil-water mixed-phase range; s3, reconstructing oil-water mixed-phase range bubbles; and S4, water holding rate imaging. For oil and water phases of a shaft of a horizontal well, when interface mixed stratified flow appears in an oil phase and a water phase, based on local water holding rate information and bubble technology information measured by a plurality of resistance probes, water holding rate reconstruction and bubble number and size reconstruction of fluid within the range of the oil phase, the water phase and the oil-water mixed phase are adopted, and water holding rate imaging of the mixed stratif
