Description
Technical field
The utility model relates to a kind of well head thorn cleaning device in oilfield downhole operation technical field of construction, particularly a kind of closed sucker rod well-head thorn cleaning device.
Background technology
Conventional Downhole Construction, washes down wax to the thorn tripping out sucker rod, is emitted on the sucker rod bridge near well site, then carries out stinging the oily wax washing surface with superheated vapor mixed liquor, reaches the standard of going into the well.A large amount of sump oil sewage can be produced to fall earthward in the washed journey of thorn, cause environmental pollution.
Summary of the invention
Technical problem to be solved in the utility model overcomes in the washed journey of existing thorn that exists in background technology can produce a large amount of sump oil sewage and fall earthward and cause the problem of environmental pollution, and provide a kind of closed sucker rod well-head to sting cleaning device, this closed sucker rod well-head thorn cleaning device, sump oil sewage is recovered to assigned address in time, realizes cleaning Downhole Construction.
The invention for solving the technical problem reaches by following technical scheme: this closed sucker rod well-head thorn cleaning device, comprise top connection, lower contact, main body, the top and the bottom of described main body are connected with top connection, lower contact respectively, and the space that described main body and top connection are formed is built with self-sealing core and pressure ring; Several nozzles of the equidistant connection of centrum shape position, middle part circumference of main body; Centrum shape position upwards outside connecting ring cavity outer wall in the middle part of main body, form high pressure ring cavity between the middle part centrum shape of main body and ring cavity outer wall, draw hole six decile and be welded on ring cavity outer wall, plug is connected to and draws hole 5, ring cavity outer wall lower end has inlet, and lower body part has recovery port.
The utility model can have following beneficial effect compared with above-mentioned background technology: this closed sucker rod well-head stings cleaning device owing to adopting said structure, adopt that high-pressure nozzle, six etc. is divided equally, the principle of fan-shaped liquid level, the comprehensive thorn in sucker rod surface is washed, reaches the object that sucker rod surface oil wax is peeled off instantaneously.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1-top connection, 2-self-sealing core, 3-pressure ring, 4-ring cavity outer wall, 5-draws hole, 6-plug, 7-inlet, 8-nozzle, 9-main body, 10-recovery port, 11-lower contact.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this closed sucker rod well-head thorn cleaning device comprises top connection 1, lower contact 11, main body 9, and screwed connection is leaned on top connection 1, lower contact 11 respectively in the top and the bottom of described main body 9; The space that main body 9 and top connection 1 are formed is built with self-sealing core 2 and pressure ring 3, and described self-sealing core 2 upper side is butted on pressure ring 3 inside top, and pressure ring 3 bottom surface is seated at top, self-sealing core 2 bottom; Centrum shape position, the middle part equidistant screwed connection of circumference 6 nozzles 8 of main body 9; Centrum shape position, the middle part upwards outside connecting ring cavity outer wall 4 of main body 9, high pressure ring cavity is formed between the middle part centrum shape of main body 9 and ring cavity outer wall 4, drawing hole 5 six decile is welded on ring cavity outer wall 4, plug 6 screwed connection is being drawn on hole 5, ring cavity outer wall 4 lower end has inlet 7, nozzle 8 is with to draw hole 5 concentric corresponding, and main body 9 bottom has recovery port 10.
This closed sucker rod well-head thorn cleaning device is by clamp connection at well head place, and sucker rod cross-under is between upper lower contact.HTHP steam mixed liquor is entered in high pressure ring cavity by inlet, then is washed on the surface of sucker rod by the fan-shaped thorn of nozzle, thus completes and carry out thorn to up sucker rod and wash, and the sump oil sewage wherein produced is recovered to assigned address by recovery port.The whole process tripping out sucker rod is also the cleaning process to sucker rod, realizes cleaning environmental protection operation.
