Abstract


Top drive full named TOP DRIVE DRILLING SYSTEM, it is the 1980s, the rise of a new drilling technology in the field of international drilling, is the rotation of a major breakthrough in drilling technology. Top drive instead of the traditional rotary drilling, can save the time of taking single drill and interval; With complex geological condition, can take single drill at any time, reducing the occurrence of sticking. Top drive drilling system direct rotate drill pipe from the derrick upper space, and along the special track sent down to complete the drill rotary drilling, circulating drilling fluid, Connecting column, installing shackle and back reaming, etc. The system significantly improves the capacity and efficiency of drilling operations, and has become a standard product in oil drilling industry.Combining the research status and development trend of domestic and foreign top drive, can clearly see the great distance of domestic and foreign top drive in technical design or manufacturing process. Top Drive has become a technical barrier of China’s oil industry toward the world. The subject based on the practical application of domestic and foreign top drive, analysis the performance of the domestic, propose the optimization of the domestic. According to the hydraulic system works of top drive, application of CAD technology to design three-dimensional drawings and two-dimensional drawings of top drive hydraulic valve plate. Field trips and practice application of top drive, to further optimize the top drive hydraulic system, complete construction drawings. Build a test rig, with experimental tests of the design goals of top drive hydraulic valve plate design goals. Further optimize the top drive hydraulic system, obtain the final plan.Solve the problem of top drive hydraulic system leak. From actual conditions, combining the hydraulic sealing technology of foreign top drive to propose the improvement sealing solutions of domestic top drive. From the material and principle, further explore the low temperature hydraulic sealing of top drive.Finally, the optimization will field-tested to test the performance of top drive hydraulic system and further optimize the hydraulic system of top drive. For the domestic top drive manufacturing production to lay the foundation.
