Paper Abstract

Due to the serious partial-wear of rods and tubes and a lack of visual simulation system in the oil field, we design a visualization simulation system for the partial-wear of pumping well rods and tubes. The static visualization simulation of well trajectories and tubes, and the dynamic visualization simulation of the sucker rods motion states and the contact state of tubes and rods are realized. The method of reversely seeking the control polygon vertex of cubic B-spline curve is used in the well trajectory curve reconstruction. The method of combining circle division is proposed to solve the problem of translucent and semi-section display of tube with arbitrary 3D well trajectory as the axis. The visualization simulation of the dynamic deformation of sucker rods and the contact state between tubes and rods are realized by combining the real time partial-wear points and the well trajectory data points. The field tests show that the system can identify the position and state of tubes and rods’ eccentric-wear clearly, which provides basis for diagnosis and treatment.
