Description
Technical field
The utility model relates to a kind of well head high-pressure injection device, belongs to oil field light maintenance operation and uses the wellhead assembly technical field.
Background technology
At present, during the light maintenance job execution of oil field, earlier sucker rod is tripped out, put then, wash with the boiler car thorn, this kind mode is promptly wasted the water source, and thorn does not wash clean again, particularly contaminated environment.
Summary of the invention
The purpose of the utility model provides a kind of well head high-pressure injection device that can dispose greasy filth, incrustation scale and the foul on sucker rod surface at well head in order to solve the defective of the contaminated environment that exists in the oil field light maintenance job execution process.
The utility model is by the upper body, and ejector block, nozzle, lower body, lower contact are formed, and upper body, lower body, lower contact are threaded successively, and the upper body is the tubular body that the upper end has central through hole, has the inlet opening on its side pipe wall; Ejector block is installed in the cavity of upper body, and its cross section is " X " shape, and has central through hole, between the cavity inner wall of ejector block and upper body, sealing ring is installed, and nozzle is installed on the ejector block; Lower body is a tubular body, has weep hole on its side pipe wall.
The beneficial effect of the utility model is thoroughly to remove fouls such as the surperficial cured pledge of sucker rod, incrustation scale, greasy filth, realization well head safe environmental protection job execution at well head.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Can know by Fig. 1; The utility model is by upper body 1, and ejector block 2, nozzle 9, lower body 3, dash offset plate 4, lower contact 5 are formed, and upper body 1, lower body 3, lower contact 5 are threaded successively; Upper body 1 has inlet opening 6 for the upper end has the tubular body of central through hole 8 on its side pipe wall; Ejector block 2 is installed in the cavity of upper body 1, and its cross section is " X " shape, and has central through hole, between the cavity inner wall of ejector block 2 and upper body 1, sealing ring 10 is installed, and nozzle 9 is installed on the ejector block 2; Lower body 3 is a tubular body, has weep hole 7 on its side pipe wall.
The dash offset plate 4 that has central through hole is installed between lower body 3 and lower contact 5, when sucker rod through the time, dash offset plate 4 can play the liquid that stops in the well and return the effect in the well of bleeding of well head and liquid on it.
The upper end of described upper body 1 has jack 11, through this jack 11 can 1 inner chamber takes out easily from the upper body with ejector block 2.
The central-injection hole of described nozzle 9 is taper, can improve the jetting effect.
When carrying out oil field light maintenance job execution; The utility model is connected with wellhead flange through lower contact 5; And make the sucker rod central through hole through lower contact 5, dash offset plate 4, lower body 3, ejector block 2 and upper body 1 successively; Through the inlet opening 6 on the 1 side pipe wall of upper body, nozzle 9 inject high pressure liquid on sucker rod, flushing sucker rod lip-deep cured pledge, greasy filth, incrustation scale and foul, and enter sewage reservoir by the weep hole 7 on the lower body 3 side pipe walls and collect; Thereby, can effectively avoid because of clean the pollution that sucker rod causes on ground.
