Pose overshoot analysis of the marine spherical double plugging in twisting process
Marine spherical double plugging is a novel plugging device, which can achieve the initiative plugging in the oil and gas pipeline. In order to ensure that the plugging head will not collide with the pipeline wall and not be scratched by the drill cuttings, the analysis of twisting process is necessary to assure reliable operation. In this article, we designed the overall scheme of marine spherical double plugging and established the mathematic model of spherical double plugging. Through studying the twisting algorithm of plugging head and trajectory algorithm of plugging head contour, four dangerous points were obtained. The multi-body dynamic of the structure was built using ADAMS, and the twisting process and motion analysis of four points were analyzed. The twisting error of the plugging head between the four points and the inner wall of the pipeline was analyzed in overshoot states to obtain the maximum allowable overshoot of inserting hydraulic cylinder and twisting hydraulic cylinder. Simulation results show that overshoot of inserting hydraulic cylinder needs to be controlled within 11.5 mm and overshoot of twisting hydraulic cylinder needs to be controlled within 5.3 mm to avoid the unpredictable danger. This article will provide theoretical and technical support for the optimization design of control system and the plugging head.
