Experimental Validation on a New Valve Core of the Throttle Valve in Managed Pressure Drilling

This paper is concerned with experimental investigation of the linear opening-pressure drop ( L −Δ P ) relationship of new valve core in managed pressure drilling (MPD). Based on the linear L −Δ P relationship in theoretical results, the actual L −Δ P relationships are obtained by testing the flow r...

Based on the linear L −Δ P relationship in theoretical results, the actual L −Δ P 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 L −Δ P relationship almost agrees with the experimental result, and the accuracy of the theoretical design is validated.
