[Abstract]:The gas production wellhead device is an important surface equipment for controlling gas well production. Because of the complex topography and the formation fluid containing acidic gases C02 and H 2S, the gas recovery wellhead device in Sichuan area is seriously invalid. It has brought many kinds of safety hidden trouble. It is urgent to find the hidden trouble in time by accurate and effective detection method and safety evaluation. On the basis of full investigation and investigation, this paper puts forward a scheme suitable for testing the inner wall quality of gas recovery wellhead device, and on the basis of the proposed scheme, aiming at the high temperature and high pressure and high sulfur content inside the gas production wellhead unit, In this paper, the research and design of the measuring device for the diameter of the gas channel are carried out under the special conditions such as high velocity and small radius of curvature. The research and design of the internal inspection system and the flank steering mechanism for the auxiliary detection device entering the gas production well head. The design and kinematics analysis of the measuring arm are completed. The pressure angle of the measuring arm cam is within a reasonable design range, and the profile of the measuring arm cam can meet the requirements of measurement. The system consists of hardware system and software system. The hardware system includes an image acquisition card and a host computer, which mainly realizes image acquisition and transmission. The software system is developed with VS2010C. The research and design of steering mechanism mainly completes the selection of steering mechanism scheme, the design and assembly of each component, the realization of real-time image display and storage, and the research and design of steering mechanism. The optimization design of each component of the steering mechanism was carried out by the dimension interference which appeared in the motion simulation of the internal steering mechanism of the gas production wellhead device, and finally the steering mechanism successfully completed the internal steering of the gas production wellhead device. The simulation results show that the designed Dobby diameter detecting device can be used to detect the path diameter, and the steering mechanism can complete the steering under the condition of small curvature. The system can collect and display images in real time, and can detect the quality of inner wall. The feasibility and correctness of the method are verified. The research results of this paper will provide a reference for the further research on the quality of in-service inner wall of the gas recovery wellhead device.
