Abstract
The utility model relates to a wax and oil scraper for a borehole oil pipe, which is composed of an upper flange, an inner cylinder, an outer cylinder, a nozzle, an input pipe and a lower flange, wherein, the upper flange and the lower flange are connected with the upper and the lower ends of the inner cylinder and the outer cylinder, the nozzle is installed in the inner cylinder, and the input pipe is connected with the side face of the outer cylinder. When the utility model is used, the lower flange is connected with a large four-way joint on a borehole device of an oil well, the upper flange is connected with a self well-sealing device, and the input pipe is connected with a high-temperature and high-pressure steam source. When the utility model works, an underground oil pipe is positioned in the utility model, a boiler is started to input high-temperature and high-pressure steam which is jetted through the nozzle and is sprayed to the surface of the oil pipe with wax and thick oil on the surface, the wax and the thick oil of the surface of the oil pipe are melted under the actions of high temperature and high pressure and then are desquamated, the melted and desquamated wax and thick oil and the steam together flow into the oil well without being carried to ground, and therefore, on one hand, operators can not stick oil stain to conveniently carry out construction operation, and on the other hand, the utility model avoids environmental pollution so as to realize the environmental-protection production and enhance the environmental-protection quality, and has obvious economical and social benefits.
Description
One, technical field
The utility model is that the well head oil pipe removes the wax oil device, belongs to the engineering goods that oil field operation is used.
Two, background technology
Oil well paraffinication, oily when thick, wax and viscous crude can be attached on the tubing walls, and oil pipe can bring to ground with wax and oil, and then slowly drop to ground from oil pipe when tripping out to ground in the oil well, just causes environment pollution after dropping to ground.Particularly on ocean platform, during workover treatment, can flow into the ocean, seawater is polluted attached to the wax on the tubing wall, oil.For fear of the pollution of wax and viscous crude to ground and seawater, need manufacture some dirt retracting devices, when manufacturing and installing the dirt retracting device, need to drop into great amount of manpower and material resources, and because the defective of dirt retracting device and operator's work quality is not high, sometimes dirt can not reclaim fully, and wax and condensed oil polluted problem of environment can not finely solve.
Three, summary of the invention
The purpose of this utility model is that a kind of well head oil pipe of design removes the wax oil device, makes it when removing wax deposition, heavy oil wells oil pipe, can will dispose attached to wax on the tubing wall and viscous crude, dirt is not brought to ground, the realization environmental protection is produced, and improves environment-friendly quality, avoids environment pollution.
The purpose of this utility model is achieved in that it is made up of upper flange, inner core, urceolus, nozzle, input pipe, lower flange.Upper flange connects with inner core, urceolus upper end, and lower flange connects with inner core, urceolus lower end, and inner core is in the urceolus, and nozzle is installed on the inner core, and input pipe connects with the side of urceolus.Connecting mode of the present utility model is welding or thread connection.During use, lower flange is connected with big four on the well mouth of oil well device by bolt, and upper flange connects with self-sealing blowout preventer, and input pipe connects with the high temperature and high pressure steam source.During work, the oil pipe that removes is in the utility model, starts boiler, to the utility model input high temperature and high pressure steam, after steam enters the annular space of urceolus and inner core, penetrates through nozzle, sprays to the oil pipe surface that there are wax and viscous crude in the surface.
The beneficial effects of the utility model are: after steam sprays to the oil pipe surface, the wax and the viscous crude on oil pipe surface are come off after melting under the HTHP effect, wax after thawing comes off and viscous crude and steam together flow in the oil well, can not brought to ground, and the operator can not be stained with greasy dirt on the one hand, the convenient construction operation, the opposing party's normal plane has been avoided environment pollution, realizes environmental protection production, has improved environment-friendly quality, basis is practical also can to clean other downhole tool, has remarkable economic efficiency and social benefit.
Four, description of drawings
Accompanying drawing is an assembling drawing of the present utility model.
Among the figure: the 1st, upper flange, the 2nd, inner core, the 3rd, urceolus, the 4th, nozzle, the 5th, input pipe, the 6th, lower flange.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
The utility model is made up of upper flange 1, inner core 2, urceolus 3, nozzle 4, input pipe 5, lower flange 6.Upper flange 1 connects with inner core 2, urceolus 3 upper ends, and lower flange 6 connects with inner core 2, urceolus 3 lower ends, and inner core 2 is in the urceolus 3, and nozzle 4 is installed on the inner core 2, and input pipe 5 connects with the side of urceolus 3.Connecting mode of the present utility model is welding or thread connection.During use, lower flange 6 is connected with big four on the well mouth of oil well device by bolt, and upper flange 1 connects with self-sealing blowout preventer, and input pipe 5 connects with the high temperature and high pressure steam source.During work, the oil pipe that removes is in the utility model, start boiler, to the utility model input high temperature and high pressure steam, after steam enters the annular space of urceolus 3 and inner core 1,, spray to the oil pipe surface that there are wax and viscous crude in the surface through nozzle 4 ejections, the wax and the viscous crude on oil pipe surface are come off after melting under the HTHP effect, and wax after thawing comes off and viscous crude and steam together flow in the oil well.
