Abstract: The invention discloses an experimental system and a method for wellbore pressure testing under the coexistence of gas-kick and loss-circulation, comprising a drill string simulator, a wellbore simulator and a complex stratigraphic structure simulator communicated in sequence from top to bottom; further comprising a medium return pipeline for collecting the returning test liquid and a medium leakage module for collecting the leaking test liquid; further comprising a data acquisition system for collecting data during testing. In the present invention, the experimental system has a simple structure, and the experimental method can comprehensively cover the three stages of circulating, well shut-in and well killing during the occurrence of coexistence of gas-kick and loss-circulation, multiple groups of experiments can be conducted by changing a single variable at the same stage, thus making the experimental test results applicable to all stages of wellbore pressure control in drilling operation.
