Abstract
The invention provides an anti-corrosion high-temperature-resistant lining structure for a TP-JC oil well pipe with a special thread. The structure comprises a coupling and a pipe body which are mutually connected in a screwed mode, a slotting or non-slotting structure in the middle of the coupling is provided with a coupling lining, a pipe body lining is arranged on the inner diameter part where the pipe body is connected with the coupling in a screwed mode, and the pipe body lining abuts against the coupling lining. The anti-corrosion high-temperature-resistant lining structure for the TP-JC oil well pipe with the special thread has the advantages that the interiors of the coupling and the pipe body are both filled with lining materials of the structure, final lining materials are closely contacted through screw connection, in the oil extraction process, a corrosive medium exists, the coupling and the pipe body thread are protected, the corrosive medium is prevented from entering the thread to cause corrosion, therefore, the service life of the oil well pipe can be prolonged, and a large amount of cost is reduced for oil field users.
Description
Technical field
The present invention relates to a kind of for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure, be applicable to have the oil field user use of corroding and under high temperature hole condition condition.
Background technology
In in use TP-JC thread type oil well pipe employing process, because geologic condition is disliked slightly, there is various corrosive medium such as H2S and CO2 gas, CL ion in down-hole, the existence of these corrosive mediums, As time goes on corrosive medium can invade toward threaded interior gradually along TP-JC oil-well pipe joint mesopore position, continuous corrosion body and box cupling screw thread position, make the sealability of oil well pipe decline, and the application life of oil well pipe declines.TP-JC thread type oil well pipe not with inner lining structure in use for some time, in the middle part of box cupling and tubular body seriously corroded, can have a strong impact on the hermetic seal effect in oil pipe use procedure, greatly reduces oil pipe result of use.Develop a kind of inner lining structure of corrosion-resistant and high-temperature resistant according to the form of structure of TP-JC special thread own for this reason,
Summary of the invention
The object of the invention is based on existing TP-JC oil well pipe structure; there is provided a kind of for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure; when TP-JC special buckle nipple twist connect after box cupling concordant with body liner; be beneficial to protect screw thread to avoid being corroded the infringement of medium, extend oil well pipe application life.
For realizing above-mentioned object, the technical solution used in the present invention is to provide a kind of for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure, this structure includes box cupling, the body of mutually twisting and connecing, wherein: fluting or be not equipped with box cupling liner in notching construction in the middle part of described box cupling, simultaneously connect inner-diameter portion whose and be provided with body liner described body and box cupling are stubborn, body liner and box cupling liner are to top.
Effect of the present invention adopts inner lining structure for TP-JC thread type oil well pipe, screw thread in use can be protected in process to avoid being corroded the infringement of medium, extend oil pipe application life, save oil field client cost.The TP-JC thread type oil well pipe of lining antiseptic structure of the present invention; after stubborn connecing, box cupling liner and body liner are effectively to top; final inner lining material close contact is made by twisting to connect; have in the oil recovery process under under corrosive medium; effective blocking-up screw corrosion leakage, box cupling and body screw thread position are protected, and avoid corrosive medium to enter threaded interior and corrode; can extend oil well pipe application life, for oil field, user saves great amount of cost.

Detailed description of the invention
Be illustrated for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure of the present invention by reference to the accompanying drawings.
Of the present invention is based on by box cupling 1, body 2, body liner 3, box cupling liner 4 syndeton structure for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure design philosophy, box cupling liner 4 and body liner 3 are filled and box cupling and inner surface of tube body respectively, box cupling has fluting and two kinds of form of structure of not slotting, body needs after filling liner to process Eversible structure, after finally making box cupling and body twist to connect, both liners are to top.
For TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure, this structure includes box cupling 1, the body 2 of mutually twisting and connecing, fluting or be not equipped with box cupling liner 4 in notching construction in the middle part of described box cupling 1, twist at described body 2 and box cupling 1 simultaneously and connect inner-diameter portion whose and be provided with body liner 3, body liner 3 and box cupling liner 4 are to top.Described body liner 3, box cupling liner 4 are corrosion-and high-temp-resistant material.
In the middle part of described box cupling 1 not under notching construction, twist to connect be partially filled box cupling liner 4 in the middle part of box cupling 1 with box cupling 1, described body 2 and box cupling 1 are twisted and are connect inner-diameter portion whose and be provided with body liner 3, and with box cupling liner 4 to top.
In the middle part of described box cupling 1 under notching construction, be filled with box cupling liner 4 in the middle part of box cupling 1 in fluting, described body 2 and box cupling 1 are twisted and are connect inner-diameter portion whose and be provided with body liner 3, and with box cupling liner 4 to top.
In the middle part of described box cupling 1 under notching construction, be filled with box cupling liner 4 in the middle part of box cupling 1 in fluting, box cupling liner 4 be slotting the packed layer that to be filled with in the middle part of box cupling and to mate with coupling inner thread and being connected as a single entity to the packed layer pushed up with body 2 body liner 3.
Of the present inventionly to be achieved in that for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure function
Fig. 4 is that body processing liner turns up schematic diagram, and the exposed liner 3 at threaded pipe end position, is out of shape after high-temperature heating, extrudes inner lining material until turn up encase threaded end structure by rotating grinding tool 5.
Fig. 5 is box cupling processing liner schematic diagram, first the polyethylene material liner that box cupling inside dimension is less is put into, an eccentric bar 6 is added at liner position, bar shifts to an earlier date preheating, liner is driven to rotate by box cupling, liner pushed down by bar, and heating bar at high temperature makes liner expand and is adjacent to box cupling inside.
As shown in Figure 1, Figure 3, after identical processes body liner Eversible structure and box cupling inner lining structure, twisted box cupling and the body of tape splicing liner by screw-on machine, finally make box cupling liner and body liner to top, go into final diagram signal situation.
