Force prediction and influencing factors analysis of the coiled tubing blowout preventer in the shearing process
Source abstract
Abstract
Abstract For an accurate force prediction of BOP shearing drill pipe is of critical importance in reliable sealing of the wellhead in an emergency, based on the shear motion equation, the Treace yield criterion, sliding line field and wedge mechanics theory are applied to establish the prediction model of shearing force. The theoretical force is consistent with the simulation force in the novel shear rams simulated shearing CT90 tube process before the peak force and shear experiment verified the reliability of the numerical simulation. Further, the influences of the structural parameters of the rams on the maximum shearing force are investigated by the orthogonal test and range analysis method. The study shows that the maximum shearing force with the increase of the V-shape angle increases first and then decreases, decreases with the increase of the blade angle and the edge chamfer angle, and increases linearly with the increase of the blade mouth thickness; the optimal V-shape angle is around 75°.
