Abstract

The utility model relates to a part of an oil exploitation device, in particular to a heating cable penetration device for a well mouth steel pipe of an ocean electrical submersible pump. The technical scheme is as follows: the heating cable penetration device comprises an upper flange, a heating cable external-introducing inclined tube, a locking valve body, a lower flange and a liquid channel pipe, wherein the upper end and the lower end of the liquid channel pipe are respectively provided with the upper flange and the lower flange, the side wall of the liquid channel pipe is connected with the heating cable external-introducing inclined tube, and the tail end of the heating cable external-introducing inclined tube is provided with the locking valve body. The utility model has the advantages that the heating cable external-introducing inclined tube is additionally arranged near a connecting short section near a main channel, the end part of the heating cable external-introducing inclined tube is provided with a screwing pressure-resistant and temperature-resistant sealing device, i.e. the locking valve body. The heating cable penetration device is conveniently abutted with well mouths of various types of original ocean electrical submersible pumps, and is easy to introduce a high-strength 16mm steel pipe cable outside a shaft under the conditions of high pressure resistance and high temperature resistance in a sealing manner.

Description

Ocean submerged electric oil pump well well head steel pipe heating cable traversing device
Technical field:
The utility model relates to a kind of oil exploitation device feature, particularly a kind of ocean submerged electric oil pump well well head steel pipe heating cable traversing device.
Background technology:
At present, in offshore oil production, use the steel pipe heating cable of high strength ¢ 16mm in well wellbore, heat can efficiently to solve since oil thick, contain the cured problem that causes the submerged electric oil pump well oil pipe to stop up, carry the back pressure increase.But because of the particularity of ocean submerged electric oil pump well well head, (the well head tubing string vertically is equipped with safety valve) steel pipe heating cable can't be drawn from the wellhead equipment upper channel during with the Yu Haiyang submerged electric oil pump well, thereby the enforcement of restriction ocean submersible electric pump well shaft heating process.
Summary of the invention:
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of ocean submerged electric oil pump well well head steel pipe heating cable traversing device is provided, and improves ocean submersible electric pump well shaft heating process, solves an oil exploitation difficult problem.
Its technical scheme is: draw inclined tube, locking valve body, lower flange, fluid passage pipe outward by upper flange, heating cable and form; The two ends up and down of described fluid passage pipe are respectively equipped with upper flange and lower flange; The sidewall of fluid passage pipe connects heating cable and draws inclined tube outward, and the end that described heating cable draws inclined tube outward is provided with the locking valve body.
The beneficial effect of the utility model is: other the installing additional of other connection pipe nipple drawn inclined tube outside the heating cable in the main channel, and the inclined tube end is designed with the withstand voltage heatproof sealing device of screwing and promptly locks valve body.This device both had been convenient to dock up and down with the former ocean of polytype submerged electric oil pump well well head, was easy to the steel pipe cable high pressure resistant, that refractory seals are drawn high strength 16mm again outside pit shaft.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: upper flange 1, heating cable draw inclined tube 2, locking valve body 3, steel pipe heating cable 4, lower flange 5, fluid passage pipe 6 outward.
Embodiment:
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model draws inclined tube 2, locking valve body 3, lower flange 5, fluid passage pipe 6 outward by upper flange 1, heating cable and forms; The two ends up and down of described fluid passage pipe 6 are respectively equipped with upper flange 1 and lower flange 5; The sidewall of fluid passage pipe 6 connects heating cable and draws inclined tube 2 outward; The end that described heating cable draws inclined tube 2 outward is provided with locking valve body 3, and acting as of the utility model drawn down the interior steel pipe heating cable of oil well oil conduit safely and reliably to electric supply installation; Make oil pipe inner fluid intensification viscosity reduction, cured clearly after the efficient heating of completion steel pipe heating cable in the submerged electric oil pump well oil pipe of ocean; Reach the purpose that reduces back pressure and reduce pump lifting resistance; This is installed on special-purpose special well head top and the bottom, ocean and is connected the withstand voltage 35Mpa of back experiment, the interior fluorine rubber seal element of locking valve body can be under 250 ℃ of hot environments reliably and with long-term work.
After treating during installation that 16mm steel pipe cable is lowered to pit shaft oil pipe assigned address; Exceed ocean well head big four header field and reserve surplus 1-2m; After drawing inclined tube 2 outward, the heating cable that 16mm steel pipe cable end is introduced into the utility model passes; The exceptional well well head of lower flange and ocean submersible electric pump former drawn and connects top and the bottom, pipe nipple place and be connected in the completion; Accomplish electric heating cable again and draw inclined tube and the correct installation of locking valve body outward, the fluorine rubber seal element in the locking valve body is that the pressurized deflation is accomplished steel pipe heating cable ring portion high pressure sealing effect.Because the sealing of the fluorubber of type selecting self has high-temperature stability, therefore be suitable under the hot environment and work.
