Self-elevating drilling platform pile inserting and pulling operation simulation test system and method

The invention discloses a self-elevating drilling platform pile inserting and pulling operation simulation test system and method, and relates to the field of offshore oil and gas development, the system comprises a container, a bearing plate capable of entering the container, a plurality of ballast boxes located on the bearing plate, and a gradienter; the three pile leg assemblies movably penetrate through the bearing plate, and the three pile leg assemblies are distributed in an isosceles triangle shape; longitudinal racks are arranged on the pile leg assemblies, each pile leg assembly is provided with a gear assembly meshed with the corresponding rack and a motor used for driving the gear assembly, and the motors are installed on the bearing plate. The invention provides a self-elevating drilling platform pile inserting and pulling operation simulation test system and method, and solves one of the technical problems that a loading mode in the prior art is too single, and a test result is greatly deviated f
