Description
Technical field
It is to prevent pumpingh well wax deposition, reduce Viscosity of Heavy Crude Oil oil rig, specifically the invention belongs to the tool of oil field pumping well
It is a kind of extraction underground heat oil rig.
Background technique
In oilfield development process, glutinous waxing in production well hot-washing wax remover, viscous crude drop are a daily management service job, due to
Oil well paraffinication point and viscous crude section are in the upper section of pit shaft, and whole well sections are often carried out hot wash by the glutinous operation of normal wax removal, drop,
Hot clean-up well segment length, heat loss is big, and hot wash liquid measure is big, and longevity of service, well washing effect is poor, and well-flushing liquid is easy to happen leakage
Polluted reservoir causes oil well output to reduce, serious to need to carry out breaking block treatment and just return to normal production, and causes manpower, object
The waste of power, financial resources.
According to above-mentioned problem, technical staff have developed superconductive heat transfer paraffin-removal sucker rod for paraffin-troubled well wax control,
Viscous crude drop is glutinous.Such as Chinese patent application 201110254428.5 " underground heat superconductive heat transfer paraffin-removal sucker rod ", this sucker rod has
Double-layer vacuum chamber, the both ends of double-layer vacuum chamber are connection, are needed etc. after upper 100 sucker rod G.I.Hs in well head to tripping in
Sucker rod cavity in fill superconduction injection body, and top is sealed after having filled superconductive liquid.These work are existing
Field carries out, and implementation is highly difficult, different surely to reach quality requirement, causes heating effect bad；This technology another problem is that
It needs the connecting portion of 100 sucker rods to seal, is missed if any one of connection screw thread, poured into well liquid in entire roofbolt, lost
Go the function of heat transfer.
Summary of the invention
The object of the present invention is to provide a kind of extraction underground heat oil rigs, by the heat extraction of pit shaft middle and lower sections into pit shaft
Wax deposition and oil thick section, prevent wax be precipitated and crude oil retrogradation, and can overcome the problems, such as it is above-mentioned, save human and material resources, avoid
Pollution is generated to oil reservoir.
The object of the present invention is achieved like this: including oil pipe on casing, pump, hollow rod, continuous pipe, silk plug, connecing
Head, oil pump piston, oil pump sleeve, oil pump sleeve are connected in the lower part tripping in casing for pumping upper oil pipe, hollow oil pumping
Bar, extension bar head, oil pump piston are sequentially connected rear tripping in and pump in upper oil pipe, and oil pump piston and oil pump sleeve cooperation are pumped,
Conduction oil is filled in hollow rod, the conduction oil being filled with cannot be flow in the upper oil pipe of pump from extension bar head, the lower part of continuous pipe
Silk plug is installed, the lower part of continuous pipe close, to continuous pipe in inject superconductive liquid, the amount of the superconductive liquid being filled with is continuously to manage
(4) 15-25% of bore volume, in continuous pipe tripping in hollow rod.
The beneficial effects of the present invention are: after the superconductive liquid for the 15-25% for being filled with volume in continuous pipe, inside continuous pipe
Be evacuated, using vacuum tube superconductive heat transfer mechanism, the heat of oil pipe lower section by the heat-conducting oil heating in hollow rod lower section,
Conduction oil after heating makes the heating vaporization of the superconductive liquid in continuous pipe, and the heat of oil pipe lower section is passed to hollow rod rapidly
Upper section, be heated the upper section of hollow rod, the upper section of the hollow rod after heating transfers heat to upper section again
In well liquid in oil pipe, so that the well liquid temperature of oil pipe upper section is higher than wax deposition temperature, prevent wax to be precipitated, play the role of wax control, oil
Viscosity declines after the well liquid temperature of pipe upper section increases, and can normally be produced, the present invention not external heat source, less investment, in continuous pipe
Being filled with the superconductive liquid of the 15-25% of volume and vacuumizing is to produce indoors, can guarantee processing quality, can use reliably and with long-term,
Compared with prior art, have the advantages that it is at low cost, high-quality, do not pollute stratum, be easy to implement, using effect it is good.
Detailed description of the invention
Attached drawing 1 is the installation diagram of the embodiment of the present invention.
Specific embodiment
1 pair of the embodiment of the present invention is illustrated with reference to the accompanying drawing.
The embodiment of the present invention as shown in Figure 1 include casing 1, oil pipe 2 on pump, hollow rod 3, continuous pipe 4, silk plug 5,
Extension bar head 6, oil pump piston 7, oil pump sleeve 8, oil pump sleeve 8 are connected in the lower part tripping in casing 1 for pumping upper oil pipe 2,
Hollow rod 3, extension bar head 6, oil pump piston 7 are sequentially connected rear tripping in and pump in upper oil pipe 2, oil pump piston 7 and oil well pump
The cooperation of pump barrel 8 is pumped, and is filled with conduction oil in hollow rod 3, and the conduction oil being filled with cannot flow to the upper oil pipe of pump from extension bar head 6
In 2, silk plug 5 is installed in the lower part of continuous pipe 4, closes the lower part of continuous pipe 4, the inner injection superconductive liquid of continuous pipe 4, and what is be filled with is super
The amount of drain body is the 15-25% of continuous 4 bore volume of pipe, and continuous pipe 4 is evacuated after being filled with superconductive liquid, the upper end closing,
In 4 tripping in hollow rod 3 of continuous pipe, continuous pipe 4 is immersed in the conduction oil in hollow rod 3.It is filled in continuous pipe 4
The superconductive liquid of 15-25% and to vacuumize be to carry out (do not have at the scene construct) indoors.
Oil pipe 2 is sitting on wellhead assembly on pump, and the upper end of hollow rod 3 is suspended on pumping unit, the upper end of continuous pipe 4
Sealing is kept between hollow rod 3.
It after the superconductive liquid for the 15-25% for being filled with pipe internal volume in continuous pipe 4, will be evacuated, utilize inside continuous pipe 4
Vacuum tube superconductive heat transfer mechanism, the heat of 2 lower section of oil pipe is by the heat-conducting oil heating in 3 lower section of hollow rod on pump, after heating
Conduction oil make the heating vaporization of the superconductive liquid in continuous pipe 4, the heat for pumping upper 2 lower section of oil pipe is passed into hollow rod rapidly
3 upper section is heated the upper section of hollow rod 3, and the upper section of the hollow rod 3 after heating transfers heat to upper section again
Pump in well liquid in oil pipe 2, so that the well liquid temperature for pumping 2 upper section of oil pipe is higher than wax deposition temperature, prevent wax to be precipitated, play
Wax control effect, viscosity declines after the well liquid temperature of oil pipe upper section increases, and can normally be produced.
