Abstract
The invention discloses a high-efficiency maintenance device for an oil pipe. The high-efficiency maintenance device for the oil pipe comprises a booster pump, a hose and a spray head, a flushing spray orifice set is arranged on the front side portion of the spray head, a rear thrust spray orifice set is arranged on the rear side portion of the spray head, the booster pump compresses water, the compressed water flows to the spray head through the hose, the compressed water is sprayed through the flushing spray orifice set of the spray head to the oblique front portion to flush the inner wall of the maintained oil pipe, the compressed water is further sprayed through the rear thrust spray orifice set to the oblique rear portion to the inner wall of the maintained oil pipe to drive the spray head to move forward in the maintained oil pipe. The flushing spray orifice set is composed of four spray orifices with an inclined angle of 45 degrees, and the rear thrust spray orifice set is composed of six spray orifices with an inclined angle of 60 degrees. By means of the high-efficiency maintenance device for the oil pipe, high-efficiency maintenance can be rapidly conducted on a high-temperature, high-pressure and air-tightness oil pipe pulled out on site, and the requirements for making the oil pipe placed into a well again can be met; on-site operation time is saved, the workload of on-site staff is reduced, and therefore it is guaranteed that follow-up operations can be completed smoothly.
Description
Technical field
The present invention relates to 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.
Summary of the invention
The object of this invention is to provide the efficient care device of a kind of oil pipe, 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 solution adopted in the present invention 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.
Beneficial effect of the present invention:
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 present invention is described in further detail:
Fig. 1 is structural representation of the present invention;
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
Technical scheme of the present invention is understood better in order to make those skilled in the art, below in conjunction with the drawings and specific embodiments, the present invention 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 present invention 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 present invention, but the present invention can also adopt other to be different from other modes described here and implement, and therefore, can not be interpreted as limiting the scope of the invention.
In a word; those skilled in the art although the present invention lists above-mentioned preferred embodiment, should illustrate, although can carry out various change and remodeling; unless such change and remodeling deviate from scope of the present invention, otherwise all should be included in protection scope of the present invention.
