Detailed description of the invention
Fig. 1 is the installation diagram of the embodiment of the present invention.
Fig. 2 is the structure chart after continuous pipe cladding insulating layer and protective layer.
Specific embodiment
The embodiment of the present invention is illustrated with reference to the accompanying drawing.
As seen from the figure, the embodiment of the present invention include suspension arrangement 2, continuous pipe 3, hollow rod sealer 7, flow tee 8,
Hollow stem 9, wellhead assembly 10, casing 11, oil pipe 12, crossover sub 16, oil pumping pump connecting link 17, flow tee 8 are mounted on well
On mouthful device 10, casing 11, oil pipe 12 top be mounted under wellhead assembly 10, the top of oil pipe 12 is communicated with flow tee 8,
Oil pipe 12 is in casing 11, the top of the annular space between oil pipe 12 and casing 11 and the sleeve valve installing port of wellhead assembly 10
It communicates, the pump barrel of oil well pump is connected to the lower part of oil pipe 12, the lower part coupling adapter 16 of hollow stem 9, crossover sub 16
Lower part connection oil pumping pump connecting link 17, the piston of the lower part connection oil well pump of oil pumping pump connecting link 17, hollow stem 9, crossover sub
16, pump pump connecting link 17, oil well pump piston be sequentially connected in rear tripping in oil pipe 12, hollow rod sealer 7 is mounted on fuel-displaced
In threeway 8, the top of hollow stem 9 is pierced by hollow rod sealer 7, hollow stem 9 and the mating sealing of hollow rod sealer 7, makes to extract out
Crude oil can only drain from flow tee 8, be named as threeway herein, be not necessarily threeway, be also possible to four-way, hollow stem
The ectosome of 9 upper end connection suspension arrangement 2, in continuous 3 tripping in hollow stem 9 of pipe, the bottom of continuous pipe 3 is close to hollow stem 9
Bottom, but their bottom does not contact, and the upper suspension of continuous pipe 3 is in the inner body of suspension arrangement 2, the ectosome of suspension arrangement 2
On have water inlet interface 1, return water interface 4, the water inlet interface 1 communicates that (sealing inside suspension arrangement 2 is real with continuous pipe 3
It is existing), the circular passage returned between water interface 4 and continuous pipe 3 and hollow stem 9 communicates, insulating layer 5 is coated on continuous pipe 3,
Insulating layer 5 and the outer wall of continuous pipe 3 are closely affixed, and have certain cohesive force, and when use will not fall off, in 5 outer cladding of insulating layer
Protective layer 6 does not coat insulating layer 5, protective layer 6 in the connecting portion of continuous 3 top of pipe and suspension arrangement 2, for filling with suspension
2 connections use is set, because insulating layer 5, protective layer 6 cannot bear axial tension, has 10-50m not coat guarantor in the lower part of continuous pipe 3
Warm layer 5, protective layer 6 make it have 10-50m to begin to conduct heat in the lower part of continuous pipe 3, heating effect can be improved, and continuously manage
3 lower part does not coat insulating layer 5,6 sections of protective layer upper setting linked holes 13, prevents the bottom deposit sundries of hollow stem 9 by runner
After blocking, circulation canal can be continuously formed from the linked hole 13.
Further measure of the invention is that anti-blocking slot 15 is arranged in crossover sub 16, continuous 3 lowered for any reason of pipe to conversion
When on connector 16, the fluid that continuous pipe 3 flows in crossover sub 16 remains to circulation.
Further measure of the invention, which is that the bottom installation of continuous pipe 3 is anti-, meets and discusses 14, and fluting is arranged at the anti-lower part met and discussed, even
When continuous pipe is fallen on crossover sub, the fluid that continuous pipe flows in crossover sub remains to circulation.It can when removing continuous pipe 3
To prevent from breaking the lower part of continuous pipe 3, the lower part outlet of continuous pipe 3 is kept to have maximum area of efflux.
The effect of protective layer 6 is that insulating layer 5 is prevented to be damaged in transport, storage, rountrip, the surface of protective layer 6
Very smooth, frictional surface coefficient is low, convenient for removing in hollow stem 9.
The polished rod eye of pumping unit blocks hollow stem 9, and stuck point when pumping unit moves back and forth, makes hollow under suspension arrangement 2
Bar 9 and the movement of interior 3 synchronous reciprocating of continuous pipe are pumped.Hot aqueous medium is the hot water that well head boiler generates, and hot water is from water inlet
Interface 1 enters, through continuous pipe 3 to flowing down, then through the circular passage between continuous pipe 3 and hollow stem 9 to upstream, from returning water interface
4 outflows, form closed hot water circulation, make the viscous crude in the heat transfer rail 12 for the hot water squeezed into, viscous crude is made to be heated drop
It is glutinous, increase mobility, so that heavy oil wells is normally produced, moreover it is possible to reduce oil well energy consumption.
