Description

Oil pipe inner wall hydraulic rotary on-line cleaner
Technical Field
The utility model relates to an oil field, a rotatory online purger of oil pipe inner wall hydraulic pressure for oil well maintenance operation in oil field specifically says so.
Background
At present, the cleaning technology for the inner wall of an oil pipe has two modes of ground cleaning and online cleaning. The ground cleaning mode is that oil pipes are arranged on the pipe rows, a ground tool is used for cleaning the inner walls of the oil pipes, oil-containing sewage generated by cleaning is collected by a liquid receiving tank, the inner walls of the oil pipes cleaned by the mode are clean and accord with the requirement of going into a well, and the mode is the most common cleaning mode but cannot be cleaned on line.
The on-line cleaning mode is a new technology for clean operation and construction of oil fields, and needs to be matched with an underground oil drainer or an oil drainage pump for use. After crude oil in the oil pipe is discharged out, before the oil pipe is lifted, an inner wall cleaning tool is put into the oil pipe, and the tool is driven downwards into a well bottom by utilizing hydraulic pressure or air pressure, so that the aim of scraping wax and dead oil attached to the inner wall of the oil pipe is fulfilled. The cleaning tools are generally applied to scraping wax and dead oil on the inner wall of the oil pipe by rubber, and have the problems that the pressing pressure is high, the pressing is not movable under the condition of serious wax deposition, the water which enters the oil pipe newly cannot be discharged and the like.
SUMMERY OF THE UTILITY MODEL
In order to overcome current online cleaning device and suppress pressure big, suppress when the waxing is serious and beat motionlessly, and make the log raft that newly got into in the oil pipe not enough of discharging, the utility model provides a rotatory online purger of oil pipe inner wall hydraulic pressure, this rotatory online purger of oil pipe inner wall hydraulic pressure relies on the gravity of self just can fall, and hydraulic drive rotor is rotatory and drive the scraper rotation when the whereabouts, scrapes the oil wax of oil pipe inner wall. The water pressure that needs is little, and the cleaning time is short, and drive water can drive the scraper through the device is inside, and water can flow downwards from outer wall and inside pipe wall space simultaneously, reaches the effect of further washing the inside wall of oil pipe. Finally, water is driven to flow out of the oil pipe through the oil drain or the oil drain pump and back out of the wellhead from the casing.
The technical scheme of the utility model is that: a hydraulic rotary online cleaner for the inner wall of an oil pipe comprises a connector and an outer barrel, wherein the connector is in threaded connection with the outer barrel, the right end of the outer barrel is connected with a scraper seat, a nozzle is arranged at the right end of the connector, the interior of the nozzle is connected with a rotor shaft at the left end of a primary rotor, the rotor shaft at the right end of the primary rotor is connected to a tail hole sleeve, the right end of the primary rotor is sequentially connected with a secondary rotor and a tertiary rotor through a rotor shaft coupler, and the right end of the tertiary rotor is connected with a scraper through a scraper coupler; the connector is internally provided with a connector inner pore passage, the nozzle is provided with a nozzle pore passage, the tail pore sleeve is provided with a tail water jacket pore passage, and the scraper seat is provided with a scraper seat pore passage.
The right end of the three-stage rotor is sequentially connected with a plurality of rotors, and the rotor at the rightmost end is connected with a scraper through a scraper coupling.
The joint inner pore passage, the tail water jacket pore passage and the scraper seat pore passage are all axial, the nozzle pore passage is spiral, and the spiral direction is consistent with the spiral direction of the primary rotor.
The utility model discloses following beneficial effect has: (1) the oil pipe inner wall hydraulic rotary online cleaner is directly thrown into the oil pipe and can fall down by the self gravity, unlike the rubber cleaning tool which needs to go down by water pressure; (2) when the oil pipe falls down, the rotor is driven to rotate by hydraulic force and drives the scraper to rotate, so that oil wax on the inner wall of the oil pipe is scraped; (3) the cleaner ensures the cleaning requirement of the inner wall of the oil pipe after passing through the cleaner, the required water pressure is small, the cleaning time is short, and after the cleaning is finished, water can flow downwards from a gap between the outer wall and the inner wall of the oil pipe and flows out of the oil pipe through the oil drain device or the oil drain pump.
