Design and Research on the Automatic Pipe Laying Device of Workover Rigs

Abstract

 Well workover is an essential operation process in oilfield, and tubulars, overhauling the transportation of between pipe racks and wellhead platforms forhas long been a big problemoil rods and other tubing. Due to the inadequacy of devicesthe related tubulars transportation, there are problems such as low efficiency and insufficient safety in operationsheavy workload, tubulars lifting and lowering. Some domestic oilfields still use manual operation or semi-automated mode, which is easy to cause wear and tear of tubing, low efficiency and safety hazards. In order to solve these problems, this paper develops a set of intelligent pipelining system to improve the safety and process efficiency. First of all, we review the literature of related devices, summarize the development status of devices, domestic and foreign pipe transport design the overall scheme of , including the overall layout of the device and the detailed design of the main mechanism and force calculation, and by using automatic operationspipe removal for well workover model and assemble the device three-dimensional modeling software. utilized SolidWorks ANSYS Workbench software is to carry out static strength calibration of the main components to verify whether the structure meets the strength requirements under the maximum stress situation. Mathematical equations of kinematics and dynamics are established for the to provide theoretical basis for the motion simulation, and by using important mechanisms motion simulation of the main mechanisms and components is carried out software to verify their stability, safety and whether they can arrive at the expected motion attitude during the motion process.ADAMS.
