Design and Application of Drilling Wire Rope Guide Wheel Arrangement for Marine Derrick
The measurement experience of the on-site weight indicator system in oilfield drilling and workover rig operations shows that the measurement accuracy of the drilling rig weight indicator system is often affected by the unreasonable installation design of the dead line anchor.In order to improve the measurement accuracy of the self-lifting mast weight indicator system and ensure that the reading of the weight indicator can truly reflect the tension at the dead line end of the drilling wire rope,this article takes a certain offshore self-lifting derrick as an example to analyze the direction of drilling wire rope and the in-stallation angle of the dead line anchor,and summarizes the basic principles for the arrangement of the dead line anchor as-sembly.The C language program is used to optimize the installation angle of the guide wheel.Finally the problem of dead line tension loss caused by unreasonable installation angle of the guide wheel is solved,thereby improving the measurement accura-cy of the drilling rig weight indicator system.
