Description
Technical field
The utility model relates to a kind of oilfield production equipment, particularly a kind of novel hollow sucker rod.
Background technology
At present, in field produces, hollow rod is to effectively exploit Gao Ning, high sticky, high wax content oil and the special type sucker rod produced, except by the central duct of hollow rod to down-hole inject heat transfer medium (deep fat, hot water, steam), chemical agent or under enter heating cable and carry out viscosity reduction wax melting, improve crude oil fluidity; Also can be used for sand washing, separate salt, slim-hole is recovered the oil and oil production by layer; Its rigidity can being utilized simultaneously large, bearing the large feature of moment of torsion for driving subsurface progressive cavity.
But existing hollow rod Problems existing is: great majority seal with the form of O type circle, upper, unload screw thread time, need the body of rod rotating sucker rod, the sealing of this structure is easily revealed, and is unable to undergo high pressure, and, existing hollow rod upper, unload screw thread time labour intensity large.
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 novel hollow sucker rod, can realize the sealing that hollow rod is good, also can reach the object of bearing higher fluid pressure and mechanical shock pressure.
Its technical scheme is: be made up of the body of rod, top connection, welding piston head and adapter sleeve, one end of the described body of rod connects top connection, other end connecting welding piston head, welding piston head installs adapter sleeve, end face junction between the top connection of a body of rod and the welding piston head of another root body of rod installs red copper pad additional, the end of welding piston head studs with O type circle, and one end of top connection is provided with many prismatics box cupling, and the other end is provided with external screw thread; One end of adapter sleeve is connected with the external screw thread of top connection, and the other end coordinates with welding piston head.
Above-mentioned adapter sleeve is made up of thick body and thin body, and the inwall of thick body is provided with internal thread, and outer end is provided with guiding groove; The inner of thick body is connected with thin body, and the outer wall of described thin body is provided with spanner groove.
The side of above-mentioned welding piston head is provided with multiple O type ring recess.
The internal diameter of above-mentioned end face junction is greater than the internal diameter of hollow cavity, and red copper pad is installed in end face junction.
The beneficial effects of the utility model are: can realize the good sealing of hollow rod by red copper pad and O type circle and adapter sleeve, also can reach the object of bearing higher fluid pressure and mechanical shock pressure; Additionally by adapter sleeve, welding piston head is connected with top connection, adapter sleeve not only can play a protective role but also can upper, unload screw thread time the just adapter sleeve part that turns, effectively must reduce labour intensity.
