摘要
Abstract
Conducting ring is the key part of the intelligent drill pipe conductivity and reliability. The paper introduces the conducting ring structure of the processed intelligent drill pipe. An inner conducting ring and an outer conducting ring in this structure were located at the end of the internal diameter of threads of the pin and box connectors of the drill pipe. The contact of the cylindrical surfaces of the two rings realizes the power and signal communication at the drilling joints. We analyze the stress of conducting ring deformation process in an indoor experiment of break-out and make-up connections,and proved that a axial force F is the main reason of conducting ring deformation,and with the finite element analysis software,we make a numerical simulation of the contact process between inner and outer ring and the conductive ring status under the axial force F respectively. Simulation results indicate that the conducting rings will not be plastic deformation and have high reliability if the magnitude of interference is less than 0.024 mm and the taper of joint surface is greater than 1:5.关键词
