Abstract

The utility model provides a be used for corrosion -resistant high temperature resistant lining structure of special knot oil well pipe of TP -JC, this structure is including each other twisting coupling, the body that connects coupling middle part fluting or do not slot and all be equipped with the coupling inside lining in the structure is in simultaneously the body is twisted with the coupling and is connect the internal diameter part to be equipped with body inside lining, body inside lining and coupling inside lining opposite vertex. The utility model discloses an effect is that the inside lining material of the structure is filled respectively inside coupling and body, makes final lining material in close contact with through twisting to connect, has the oil recovery in -process corrosive medium under, and protection coupling and body screw thread corrode inside avoiding corrosive medium entering screw thread, can prolong oil well pipe life under this kind of condition, saves a large amount of costs for the oil field user.

Description

For TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure
Technical field
The utility model relates to a kind of for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure, is applicable to oil field user when having corrosion and high temperature hole condition and uses.
Background technology
In use in TP-JC thread type oil well pipe employing process, owing to 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 at position, hole in TP-JC oil well pipe joint, constantly corrosion pipe body binds round screw thread position with connecing so that the sealing property decline of oil well pipe, the decline in work-ing life of oil well pipe. The TP-JC thread type oil well pipe of band inner lining structure is not in use for some time, connect hoop middle part and pipe body internal corrosion serious, seriously can affect the hermetic seal effect in oil pipe use procedure, greatly reduction oil pipe result of use. Develop the inner lining structure of a kind of corrosion-resistant and high-temperature resistant according to the structure formation of TP-JC special thread own for this reason,
Summary of the invention
The purpose of this utility model is based on existing TP-JC oil well pipe structure; there is provided a kind of and it is used for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure; when TP-JC special buckle threaded connector twist connect after connect hoop concordant with pipe body liner; it is beneficial to protection screw thread and avoids the infringement being corroded medium, extend oil well pipe work-ing life.
For realizing above-mentioned object, the technical solution adopted in the utility model 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 include mutually twist connect meet hoop, Guan Ti, wherein: described connect hoop middle part fluting or notching construction be not equipped with connect hoop liner, simultaneously connect hoop at described Guan Tiyu to twist and connect inner-diameter portion whose and be provided with pipe body liner, pipe body liner with connect hoop liner to top.
Effect of the present utility model adopts inner lining structure for TP-JC thread type oil well pipe, screw thread in use can be protected in process to avoid the infringement being corroded medium, extend oil pipe work-ing life, save oil field client cost. The TP-JC thread type oil well pipe of the lining antiseptic structure of the present invention; twist connect after connect hoop liner and pipe body liner effectively to top; by twisting to connect, final inner lining material is in close contact; in the oil recovery process having under under corrosive medium; effectively blocking-up screw thread corrosion leakage channel, connects hoop and pipe body screw thread position is protected, and avoids corrosive medium to enter threaded interior and corrodes; can extending oil well pipe work-ing life, for oil field, user saves great amount of cost.

Embodiment
It is illustrated for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure of the present utility model by reference to the accompanying drawings.
Of the present utility model for TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure design philosophy be based on by connecing hoop 1, pipe body 2, pipe body liner 3, connect hoop liner 4 and connect architecture, connect hoop liner 4 and pipe body liner 3 fill respectively and connect hoop and inner surface of tube body, connect hoop and there are fluting and two kinds of structure formations of not slotting, pipe body needs processing Eversible structure after filling liner, finally make to connect hoop and pipe body twist connect after, both liners are to top.
For TP-JC special buckle oil well pipe corrosion-resistant and high-temperature resistant inner lining structure, this structure include mutually twist connect connect hoop 1, pipe body 2, described connect in the middle part of hoop 1 fluting or notching construction be not equipped with connect hoop liner 4, simultaneously described pipe body 2 with connect hoop 1 and twist and connect inner-diameter portion whose and be provided with pipe body liner 3, pipe body liner 3 with connect hoop liner 4 to top. Described pipe body liner 3, connect hoop liner 4 be corrosion-and high-temp-resistant material.
Connect in the middle part of hoop 1 not under notching construction described, connect in the middle part of hoop 1 with connect hoop 1 and twist to connect to be partially filled and connect hoop liner 4, described pipe body 2 with connect hoop 1 and twist and connect inner-diameter portion whose and be provided with pipe body liner 3, and with connect hoop liner 4 to top.
Connect in the middle part of hoop 1 under notching construction described, connect to be filled with in fluting in the middle part of hoop 1 and connect hoop liner 4, described pipe body 2 with connect hoop 1 and twist and connect inner-diameter portion whose and be provided with pipe body liner 3, and with connect hoop liner 4 to top.
Connecing in the middle part of hoop 1 under notching construction described, connect to be filled with in fluting in the middle part of hoop 1 and connect hoop liner 4, connecing hoop liner 4 be connect hoop middle part at fluting be filled with the packing layer mated with coupling inner thread and to the packing layer pushed up and be connected as a single entity with pipe body 2 pipe body liner 3.
Of the present utility model it is 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 pipe body processing liner turns up schematic diagram, and the exposed liner 3 at threaded pipe end position, is out of shape after heat, extrudes inner lining material until turning up and encasing threaded end bilge construction by rotating grinding tool 5.
Fig. 5 is for connecing hoop processing liner schematic diagram, first it is put into and connects the less polyethylene material liner of hoop interior dimensions, an eccentric bar 6 is added at liner position, bar preheating in advance, rotate by connecing the dynamic liner of band, liner pushed down by bar, and heating bar at high temperature makes liner expansion be adjacent to and connects hoop inside.
As shown in Figure 1, Figure 3, by identical processes pipe body liner Eversible structure with after connecing hoop inner lining structure, by twist pick twist connect band liner connect hoop and pipe body, finally make to connect hoop liner and pipe body liner to top, go into the signal situation that finally illustrates.
