  • 摘要:This paper is concerned with experimental investigation of the linear opening-pressure drop () relationship of new valve core in managed pressure drilling (MPD). Based on the linear relationship in theoretical results, the actual relationships are obtained by testing the flow rate, displacement of the valve core, and pressures at the import and export. Under all three working conditions, the theoretical relationship almost agrees with the experimental result, and the accuracy of the theoretical design is validated. In addition, the flow coefficient () is also tested in the experimental process to judge the throttling characteristics of the new valve core and the proper working conditions.
