Description
Technical field
It is the sucker rod for preventing pumpingh well wax deposition the invention belongs to the tool of oil field pumping well, specifically a kind of extraction ground
Hot hollow rod.
Background technique
In oilfield development process, hot cleanout and paraffin removal of oil well is a daily management service job, all due to oil well paraffinication point
More top, whole well sections are often carried out hot wash by normal wax removal operation, and hot clean-up well segment length, heat loss is big, hot wash liquid measure
Greatly, longevity of service, well washing effect is poor, and well-flushing liquid is easy to happen leakage polluted reservoir, and oil well output is caused to reduce, sternly
Needing to carry out breaking block treatment and capable of just returning to normal production for weight, causes the waste of human and material resources, financial resources, well rod heat tracing
It is also the production needs in oil field.
According to above-mentioned problem, technical staff has developed superconductive heat transfer paraffin-removal sucker rod for paraffin-troubled well wax control.
Such as Chinese patent application 201110254428.5 " underground heat superconductive heat transfer paraffin-removal sucker rod ", this wax control sucker rod has double-deck true
Cavity, the both ends of double-layer vacuum chamber are connection, the oil pumping after upper 100 sucker rod G.I.Hs in well head to tripping in such as need
Superconduction injection body is filled in the cavity of bar, and top is sealed after having filled superconductive liquid.These work carry out at the scene,
Implement it is highly difficult, it is different surely to reach quality requirement, cause heating effect bad；This technology another problem is that need on
The connecting portion sealing of 100 sucker rods, misses if any one of connection screw thread, is poured into well liquid in entire roofbolt, lose heat transfer
Function.
Summary of the invention
The object of the present invention is to provide a kind of extraction underground heat hollow rod, under in the wax deposition section of pumpingh well, to well liquid plus
Heat prevents wax to be precipitated, and can overcome the problems, such as above-mentioned, saving human and material resources, avoids generating oil reservoir and pollute.
The object of the present invention is achieved like this: hollow including hollow stem top connection, hollow rod body, hollow stem lower contact
Bar top connection, hollow rod body, hollow stem lower contact are structure as a whole, and screw thread on sucker rod is arranged at the top of hollow stem top connection, empty
Screw thread under sucker rod is arranged at the lower part of core bar lower contact, and screw thread matches with screw thread under the sucker rod on the sucker rod, empty
There is through-hole in the inside of core bar body, installs upper plug head in the upper end of the through-hole, upper plug head be fixed in the through-hole and with
It keeps sealing to make, and the upper end with the through-hole is blocked, and installs lower end cap in the lower end of the through-hole, lower end cap is fixed
It keeps sealing in the through-hole and with it, there is injection hole on lower end cap, the injection hole is communicated with the through-hole, warp
To after injecting superconducting fluid in the through-hole, the injection hole is sealed the injection hole by plugging mechanism, makes described logical
Superconducting fluid in hole cannot leak outside.
The plugging mechanism includes filling seal, silk plug, and filling seal is in the inner end of the injection hole, silk
It is stifled to be connect with the internal screw thread of lower end cap lower part, seal will be filled and be compressed in the injection hole.
The beneficial effects of the present invention are: the present invention injects superconductive liquid after through-hole is evacuated, vacuum tube superconduction is utilized
Heat-transfer mechanism extracts well temperature for superconductive liquid and heats vaporization, formation temperature passed to whole hollow rod body rapidly, by sucker rod
Junction (rapid heat transfer processing), and transmit upwards in turn, so that entire roofbolt is released heat, heated well by the tube wall of the body of rod
Liquid makes well liquid temperature be higher than wax deposition temperature, wax is prevented to be precipitated, plays the role of wax control, the present invention not external heat source, less investment,
The present invention produces indoors, can guarantee processing quality, can use reliably and with long-term, compared with prior art, has at low cost, quality
Well, stratum is not polluted, is easy to implement, the advantage that using effect 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 includes hollow stem top connection 1, hollow rod body 2, hollow stem lower contact 4, hollow
Bar top connection 1, hollow rod body 2, hollow stem lower contact 4 are structure as a whole, and screw thread on sucker rod is arranged at the top of hollow stem top connection 1
Screw thread 4-2 under sucker rod is arranged at 1-1, the lower part of hollow stem lower contact 4, screw thread 1-1 and the sucker rod on the sucker rod
Lower screw thread 4-2 matches, and there is through-hole 3 in the inside of hollow rod body 2, installs upper plug head 6 in the upper end of the through-hole 3, upper plug head 6 is solid
It is scheduled in the through-hole 3 and keeps sealing with it, blocked with the upper end of the through-hole 3, in the lower end of the through-hole 3
Lower end cap 5-1 is installed, lower end cap 5-1 is fixed in the through-hole 3 and keeps sealing with it, has injection hole on lower end cap 5-1
5-2, the injection hole 5-2 are communicated with the through-hole 3, through the injection hole 5-2 to the inner injection superconduction of through-hole 3
After liquid, the injection hole 5-2 is sealed by plugging mechanism, prevents the superconducting fluid in the through-hole 3 from leaking outside.
The plugging mechanism includes filling seal 5-3, silk plug 5-4, and filling seal 5-3 is in the injection hole
The inner end of 5-2, silk plug 6 are connect with the internal screw thread of the lower part lower end cap 5-1, will be filled seal 5-3 and are compressed on the injection hole
In 5-2.
