Description
Technical field
The utility model relates to a kind of oil well cleaning apparatus, especially a kind of producing well paraffin cleaning shuttle structure of improvement.
Background technology
In the process that crude oil is extracted by oil pipe from the high temperature and high pressure environment of underground, along with the change of pressure and temperature, the wax be dissolved in crude oil can be separated out from crude oil originally, and is attached to gradually on tube inner wall.The wax deposition of tube inner wall can cause oil pipe blocking, must regularly clear up.Chinese utility model patent CN 201835793 U discloses a kind of scraper for inner walls of oil tubes, by the cooperation of multiple scraper, achieves the cleaning to tube inner wall.But the scraper of this structure is connected by hinged mode, when scraper changes the direction of motion, scraper also will commutate accordingly, complicated integral structure, and reliability is lower, easily occurs the problem that articulated position is stuck and cannot work.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of producing well paraffin cleaning shuttle structure of improvement, can solve the deficiencies in the prior art, and without the need to the commutating structure of activity, structure is simple, and reliability is high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of producing well paraffin cleaning shuttle structure of improvement, comprise shuttle body, the two ends of shuttle body are symmetrically arranged with scraper, the top of described scraper is towards the sloped-end of the shuttle body far away apart from himself, the angle of scraper and shuttle body is 45 ° ~ 75 °, blade is provided with inside scraper, scraper arranged outside has pawl, containing cavities is provided with between two scrapers, containing cavities is fixed on the outside of shuttle body, the feeding-passage communicated with containing cavities is provided with in scraper, the outlet of feeding-passage is arranged on blade, blade surface is provided with primary heater, primary heater is between feeding-passage and shuttle body, shuttle body center vertical is provided with through hole, be connected by breach between containing cavities with through hole.
As preferably, the two ends of described shuttle body are respectively arranged with toroidal nozzle, and toroidal nozzle is evenly provided with several nozzles, described scraper are provided with the flowing hole of through scraper.
As preferably, in described containing cavities, be provided with secondary heater.
The beneficial effect adopting technique scheme to bring is: the utility model changes commutating structure hinged in prior art, scraper is fixedly connected with shuttle body, by rationally arranging structure and the setting angle of scraper, realize two scrapers at one time interior one carry out scraping, another carries out prune job, when shuttle body moving direction changes, the operation function of two scrapers exchanges automatically, achieves the function that can realize two-way wax removal without the need to commutating structure.Blade is used for wax removal, and pawl is for clearing up the tube inner wall through blade scraping.Move downward with shuttle body and illustrate: the scraper of top carries out scraping, the scraper of below carries out prune job.The blade of top is moving downward in process, and the wax on oil pipe is carried out scraping, and the wax under scraping is softening under the heat effect of primary heater, and is entered in containing cavities by feeding-passage.The pawl of below, at the tube inner wall through scraping, carries out secondary cleaning to tube inner wall, clears up residual wax, improves the patency of tube inner wall further.The wax entering containing cavities enters through hole through breach under the continuous extruding of outside wax, and discharges from through hole.On simple mechanical paraffin removal architecture basics, utilize toroidal nozzle to spray Wax dissolving agent in oil pipe, can soften wax, improve the shaving effect of blade.Flowing hole on scraper can make Wax dissolving agent flow through scraper, thus improves the mobility of Wax dissolving agent in scraper both sides.Secondary heater in containing cavities further can soften the wax entering containing cavities, reduces its flow resistance.
