Abstract
The utility model discloses a high -efficient maintenance device of oil pipe, including booster pump, hose and shower nozzle, front portion on the shower nozzle is equipped with and washes orifice group, and back lateral part on the shower nozzle is equipped with back thrust orifice group, and the booster pump is to water compress, and water after the compression flows into the shower nozzle through the hose, washes the syncline the place ahead blowout of orifice group on the shower nozzle, wash the oil pipe's that is maintained inner wall, still on the shower nozzle after thrust orifice group syncline rear blow out to the oil pipe's that is maintained inner wall, promote the shower nozzle and is being made way by in the oil pipe who maintains. Wash orifice group and be 45 constitute for the orifice by 4 inclinations. Back thrust orifice group is 60 constitute for the orifice by 6 inclinations. The high temperature high pressure gas tightness oil pipe that this practicality can be risen to the scene rapidly carries on maintaining high -efficiently, makes oil pipe reach the requirement of going into the well again, save the site operations time, reduce site work personnel's work load to smooth completion for follow -up operation provides the guarantee.
Description
Technical field
The utility model relates to the care device, particularly a kind of care device for HTHP hermetic seal oil pipe that oil gas bores the oil pipe temporarily tripped out for at-sea maintenance in completion and technical field of measurement and test.
Background technology
All hermetic seal oil pipe is adopted at present in offshore oil field HTHP completion and test, flowline may be run into lay equal stress on newly in operation, this requires that operation field carries out scene maintenance to the oil pipe tripped out, and guarantees that hermetic seal oil pipe is in good condition, can back into well.Mud balance used by hp-ht well is higher, and the weighting material in mud is relatively many, and the tube inner wall tripped out is with foreign material, and before oil pipe enters down again, the foreign material of inwall lump, and traditional maintenance method time length, weak effect, workload are large.
Utility model content
The purpose of this utility model is to provide the efficient care device of a kind of oil pipe, and this care device substantially increases the maintenance efficiency of oil pipe, for field operation saves the time, also provides guarantee for completing smoothly of subsequent job.
For achieving the above object, the technical scheme that the utility model adopts is:
The efficient care device of oil pipe, include booster pump, flexible pipe and shower nozzle, front side portion on described shower nozzle is provided with and rinses spray orifice group, rear lateral portion on shower nozzle is provided with back pressure spray orifice group, described booster pump compresses water, water after compression flows to shower nozzle through flexible pipe, flushing spray orifice group on shower nozzle sprays to diagonally forward, rinse by the inwall of oil pipe maintained, back pressure spray orifice group also on shower nozzle is ejected into by the inwall of oil pipe that maintains to oblique rear, promotes shower nozzle being moved forward by the oil pipe that maintains.
Further, described flushing spray orifice group is 45 ° forming for spray orifice by 4 inclination angles.
Further, described back pressure spray orifice group is 60 ° forming for spray orifice by 6 inclination angles.
Further, described booster pump can provide 20MPa pressure, 170L/min discharge capacity, and driving power is the electric drive pump of 75kw.
Further, also comprise cylinder and base, described cylinder and described booster pump are all located on base, and described soft tube winding is on cylinder.
Further, described base is located on fixed frame, and described fixed frame is provided with suspension ring.
The beneficial effects of the utility model:
1) can maintain efficiently the HTHP tightness oil pipe that scene trips out rapidly, make oil pipe reach requirement back into well.
2) save the field operation time, reduce the workload of field personnel, thus provide guarantee for completing smoothly of subsequent job.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the vertical profile of shower nozzle shown in Fig. 1.
In figure: 1, booster pump; 2, flexible pipe; 3, shower nozzle; 4, cylinder; 5, base; 6, fixed frame; 7, suspension ring; 8, by the oil pipe maintained; 9, back pressure spray orifice group; 10, spray orifice group is rinsed.
Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, it should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Figure 1, the efficient care device of oil pipe, includes booster pump 1, flexible pipe 2 and shower nozzle 3, and described booster pump can provide 20MPa pressure, 170L/min discharge capacity, and driving power is the electric drive pump of 75kw.
Also comprise cylinder 4, base 5 and fixed frame 6, described cylinder 4 and described booster pump 1 are all located on base 5, and described flexible pipe 2 is wrapped on cylinder 4.Described base 5 is located on fixed frame 6, and described fixed frame 6 is provided with suspension ring 7.During work, shower nozzle 3 extend into by the oil pipe 8 that maintains.
As shown in Figure 2, the front side portion on described shower nozzle 3 is provided with and rinses spray orifice group 10, and described flushing spray orifice group 10 is 45 ° forming for spray orifice by 4 inclination angles.Rear lateral portion on shower nozzle 3 is provided with back pressure spray orifice group 9, and described back pressure spray orifice group 9 is 60 ° forming for spray orifice by 6 inclination angles.Described booster pump 1 pair of water compresses, water after compression flows to shower nozzle 3 through flexible pipe 2, flushing spray orifice group 10 on shower nozzle 3 sprays to diagonally forward, rinse by the inwall of oil pipe 8 maintained, back pressure spray orifice group 9 also on shower nozzle 3 is ejected into by the inwall of oil pipe 8 that maintains to oblique rear, promotes shower nozzle being moved forward by the oil pipe 8 that maintains.
Operating principle: at the scene in operation process, can run into midway rise needs by the oil pipe maintained, higher for the mud balance used by hp-ht well, weighting material in mud is relatively many, the tube inner wall tripped out is with mud, before oil pipe enters down again, the mud of inwall lumps, the tradition maintenance method time is long, weak effect, workload is large, the efficient care device of HTHP hermetic seal oil pipe, pressure (hydraulic) water is utilized to clean, the mud that tube inner wall lumps just can be pulverized and take out of in pipe by this, the water simultaneously ejected can provide back pressure to make shower nozzle voluntarily forward, advance in cleaning limit, limit, substantially increase the efficiency of oil pipe maintenance like this.The utility model can maintain the HTHP tightness oil pipe that scene trips out rapidly efficiently, oil pipe is made to reach requirement back into well, maintenance ultrahigh in efficiency, within average 5 minutes, an oil pipe can be maintained, and can come back to the base after used oil pipe at the scene maintenance efficiently in time again, the defect that when causing coming back to the base after avoiding long-time transport, consolidation is seriously not easily maintained.
Set forth a lot of detail in description above so that fully understand the utility model, but the utility model can also adopt other to be different from other modes described here and implement, and therefore, can not be interpreted as the restriction to the utility model protection domain.
In a word; although the utility model lists above-mentioned preferred embodiment; but should illustrate; although those skilled in the art can carry out various change and remodeling; unless such change and remodeling deviate from scope of the present utility model, otherwise all should be included in protection domain of the present utility model.
