Abstract
The utility model relates to a kind of closed oil pipe well head thorn cleaning device.Mainly solve in prior art and can produce a large amount of sump oil sewage when flowline thorn washes down wax and the problem that causes environment pollution to rising.It is characterized in that: between described upper main body (1) and lower main body (6), be provided with nozzle ring (3), and upper main body (1) external stability has ring cavity outer wall (4), ring cavity outer wall (4) lower inside is threaded with lower main body (6), and the side of described ring cavity outer wall (4) is connected with feed tube (2).This closed oil pipe well head thorn cleaning device washes down wax to playing flowline thorn, and the sump oil sewage of generation directly falls in oil sets annular space, or is recovered to assigned address by well head big four, avoids polluting well site, realizes environmental protection operation.
Description
Technical field
The utility model relates to oilfield, is a kind of closed oil pipe well head thorn cleaning device specifically.
Background technology
The Downhole Construction of current routine, washing down wax to playing the thorn of flowline, being emitted on the oil pipe bridge near well site, then carries out thorn with superheated vapor mixed liquor and wash down oil removing wax, 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 environment pollution.
Summary of the invention
The deficiency of environment pollution is caused in order to a large amount of sump oil sewage can be produced when overcoming and wash down wax to a flowline thorn in prior art, the utility model provides a kind of closed oil pipe well head to sting cleaning device, this closed oil pipe well head thorn cleaning device washes down wax to playing flowline thorn, the sump oil sewage produced directly falls in oil sets annular space, or be recovered to assigned address by well head big four, avoid polluting well site, realize environmental protection operation.
The technical solution of the utility model is: a kind of closed oil pipe well head thorn cleaning device, comprise main body, lower main body, nozzle ring is provided with between described upper main body and lower main body, and upper body exterior is fixed with ring cavity outer wall, ring cavity outer wall lower inside is connected with lower main body screw, and the side of described ring cavity outer wall is connected with feed tube.
The utility model has following beneficial effect: owing to taking such scheme, this device is fixed on well head big four by lower main body, top is connected with self-packer, HTHP steam mixed liquor enters in high pressure ring cavity by inlet, wash by nozzle ring on the surface of oil pipe with fan-shaped thorn again, thus complete and closed thorn is carried out to up oil pipe wash, the sump oil sewage of generation directly drops in oil sets annular space, or is recovered to assigned address by well head big four.The process of whole flowline is also the cleaning process to oil pipe, realizes cleaning environmental protection operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Main body on 1-in figure, 2-feed tube, 3-nozzle ring, 4-ring cavity outer wall, 5-packing, main body under 6-.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of closed oil pipe well head thorn cleaning device, comprise main body 1, lower main body 6, upper main body 1 top is connected with simple and easy self-packer by flange, and lower main body 6 is fixed on well head big four.Be provided with nozzle ring 3 between described upper main body 1 and lower main body 6, and upper main body 1 external stability has ring cavity outer wall 4, ring cavity outer wall 4 lower inside is threaded with lower main body 6, and nozzle ring 3 can compress by ring cavity outer wall 4.And be provided with ring cavity between ring cavity outer wall 4 and upper main body 1, be provided with sealed packing 5 between ring cavity outer wall 4 and lower main body 6.The side of described ring cavity outer wall 4 is connected with feed tube 2, and feed tube 2 communicates with above-mentioned ring cavity.
When carrying out thorn to a flowline and washing down wax, because this thorn cleaning device top is sealed by Simple sealing device, liquid is entered into after in ring cavity by feed tube 2, wash on oil pipe surface by nozzle ring 3 with fan-shaped thorn, thus complete the closed thorn of up oil pipe is washed, the sump oil sewage produced directly drops in oil sets annular space, or is recovered to assigned address by the well head big four of bottom.The process of whole flowline is also the cleaning process to oil pipe, avoids polluting well site, achieves and cleans environmental protection operation.
