Zusammenfassung:The invention discloses a cable stratum test pumping value simulation and process numerical correction method. The method comprises the following steps that S1, the flow pattern of cable stratum testpressure measurement data is judged, and the corresponding flow degree is obtained; s2, a probe opens a test hole in the well wall, an invasion zone and formation fluid begin to flow to a wellbore, asampler extracts the formation fluid, the formation fluid instantly flows and forms a flowing form and continuous conduction, a war range is generated, and an ellipsoid is used for simulating the warrange formed by continuous conduction of formation fluid flowing; s3, on the basis of given reservoir physical parameters and invasion depth, the pre-test prediction pumping breakthrough time, the pumping pure time and the corresponding volume are obtained according to an algorithm; and S4, pumping monitoring parameters are tested through the cable stratum, the pumping breakthrough time and volumeare picked up, a pumping re
