Description
Technical field
the utility model relates to oil field Oil, Water, Gas well operations aid, specifically a kind of oil-water-gas well operations swivel joint.
Background technology
oil field oil, water, need in gas well operation process to carry out sand washing, cover milling, bore plug, construction is rinsed in millings etc., need to increase tubing string in time in flushing process, deepen to rinse the degree of depth, ensure to rinse carrying out smoothly of construction, due on unload in tubing string screw thread process and be subject to environment, instrument, the factor impacts such as post operative's qualification, frequent generation is unloaded tubing string skew problems, tubing string deflection causes elbow ears and suspension ring to touch extension, cause hose winding to beat to turn round, the problems such as thorn leakage, accident is got loose time serious, not only affect oil, water, gas well job scheduling, and well head operating personnel are damaged, there is potential safety hazard.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil-water-gas well operations swivel joint.
oil-water-gas well operations swivel joint, comprising: top connection, shop bolt, sealing ring, housing, upper bearing (metal), intermediate sleeve, lower bearing, lower contact.Described oil-water-gas well operations swivel joint is cylindrical shape, be provided with centre bore, lower contact and housing are structure as a whole, housing is equipped with lower bearing, intermediate sleeve, upper bearing (metal), top connection from bottom to top successively, be provided with two seals circle between intermediate sleeve and top connection, be actively coupled by shop bolt between top connection and housing.
top connection upper part in above-mentioned oil-water-gas well operations swivel joint is provided with external screw thread, and centre is provided with annular slide track.
shop bolt in above-mentioned oil-water-gas well operations swivel joint is threaded with housing, enters in the annular slide track of top connection.
top connection in above-mentioned oil-water-gas well operations swivel joint and housing produce relative rotary motion.
housing upper end circumference in above-mentioned oil-water-gas well operations swivel joint is arranged with two shop bolts, and lower part is provided with external screw thread.
