Abstract
The utility model discloses an excellent in use effect's binary oil pipe, include: interior oil pipe and with the concentric outer oil pipe who sets up of interior oil pipe, the interior oil pipe both ends outside is connected with outer oil pipe through a plurality of connectors respectively be provided with the internal channel in the interior oil pipe be provided with annular channel between interior oil pipe and the outer oil pipe interior oil pipe and outer oil pipe's no. 1 serves and is provided with toper male thread respectively be provided with the toper box thread of mutually supporting with toper male thread on interior oil pipe and outer oil pipe's the other end respectively. The advantage is: novel structure adopts concentric double -barrelled integrative technique and the concentric double -barrelled tapered thread technique of docking simultaneously, forms two circulation canal in the concentric tube, has reduced the construction degree of difficulty and risk, simple to operate, and excellent in use effect, the reliability is high, and sealing performance is strong, can not take place the minor diameter pipe strap and hinder the trouble, can adapt to deep well oil recovery application of optimization.
Description
Technical field
This utility model relates to a kind of oil exploration equipment, particularly relates to a kind of binary oil pipe.
Background technology
Concentric double pipe post Technology is often used in process for petroleum recovery technology, the technological process of this technology is: first with the tubing string being relatively large in diameter by required oil tool G.I.H, it is arranged on projected depth, then enter the less tubing string of diameter under in major diameter tubing string and insert in well in instrument, complete peripheral passage, whole down-hole, reaching technique purpose, putting into recovers the oil produces.This technique is primarily present following shortcoming: one, operational procedure is complicated, and difficulty is big, and risk is big；Two, poor reliability, the sealing property inserting docking in down-hole is difficult to ensure that；Three, it is susceptible to narrow tube jamming failure and causes process failure；Four, the application of oil recovery technique, the particularly application of deep-well oil-extraction technology are limited.
Utility model content
Technical problem to be solved in the utility model is: provide the binary oil pipe that a kind of using effect is good.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: binary oil pipe, including: inner oil tube and the outer oil pipe being arranged concentrically with inner oil tube, it is connected with outer oil pipe by some connectors respectively outside described inner oil tube two ends, it is provided with internal channel in described inner oil tube, it is provided with circular passage between described inner oil tube and outer oil pipe, one end of described inner oil tube and outer oil pipe is respectively arranged with taper male thread, the other end of described inner oil tube and outer oil pipe is respectively arranged with the taper box thread cooperated with taper male thread.
The utility model has the advantages that: above-mentioned binary oil pipe, novel structure, use concentric double pipe one body technique and concentric double pipe tapered thread docking technique simultaneously, in concentric tube, form Two-way Cycle passage, reduce difficulty of construction and risk, easy for installation, using effect is good, and reliability is high, uses tapered thread Butt sealing performance strong, narrow tube jamming failure will not occur, it is possible to adapt to the application of deep-well oil-extraction technology.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model binary oil pipe.
In figure: 1, inner oil tube, 2, outer oil pipe, 3, connector, 4, internal channel, 5, circular passage, 6, taper male thread, 7, taper box thread.
Detailed description of the invention
Particular content of the present utility model is described in detail below in conjunction with the accompanying drawings with specific embodiment.
As shown in Figure 1, binary oil pipe, including: inner oil tube 1 and the outer oil pipe 2 being arranged concentrically with inner oil tube 1, it is connected with outer oil pipe 2 by some connectors 3 respectively outside described inner oil tube 1 two ends, it is provided with internal channel 4 in described inner oil tube 1, it is provided with circular passage 5 between described inner oil tube 1 and outer oil pipe 2, one end of described inner oil tube 1 and outer oil pipe 2 is respectively arranged with taper male thread 6, the other end of described inner oil tube 1 and outer oil pipe 2 is respectively arranged with the taper box thread 7 cooperated with taper male thread 6.
When above-mentioned binary oil pipe uses, more piece binary pipe is used to connect, taper male thread 6 on first segment inner oil tube 1 and outer oil pipe 2 screws in the taper box thread 7 on second section inner oil tube 1 and outer oil pipe 2 simultaneously, and the taper box thread 7 on second section inner oil tube 1 and outer oil pipe 2 screws in the taper male thread 6 on Section of three inner oil tube 1 and outer oil pipe 2 simultaneously, realize slitless connection, it is connected with outer oil pipe 2 by connector 3 respectively outside inner oil tube 1 two ends owing to often saving, inner oil tube 1 and outer oil pipe 2 are arranged concentrically, binary oil pipe concentricity after docking is high, easy for installation, use safety, form internal channel 4 and the Two-way Cycle passage of circular passage 5 composition.
Above-mentioned binary oil pipe, novel structure, use concentric double pipe one body technique and concentric double pipe tapered thread docking technique simultaneously, in concentric tube, form Two-way Cycle passage, reduce difficulty of construction and risk, easy for installation, using effect is good, and reliability is high, uses tapered thread Butt sealing performance strong, narrow tube jamming failure will not occur, it is possible to adapt to the application of deep-well oil-extraction technology.
