Technical field

The present invention relates to oilfield, specifically a kind of tube inner wall hydraulic swing for oil well overhaul operation in oil field Turn on-line cleaning device.

Background technique

Currently, tube inner wall cleaning technique has ground cleaning and on-line cleaning two ways.Ground cleaning mode is by oil pipe It is arranged on pipe row, tube inner wall is cleaned using ground instrument, collect the oily wastewater that cleaning generates using liquid bath is connect, The tube inner wall that should be cleaned in this way is clean, meets requirement of going into the well, and is a kind of most common cleaning way, but cannot be into Row on-line cleaning.

On-line cleaning mode is a kind of new technology that oil field cleans job execution, need to cooperate underground bleeder or oil drain pump It uses.Before playing oil pipe after crude oil in oil pipe releases, inner wall washing tool is put into oil pipe, using hydraulic or air pressure by tool Shaft bottom is squeezed into downwards, realizes the purpose of the wax and dead oil that shave tube inner wall attachment.The commonly used rubber of these cleaning means comes The wax and dead oil for scraping tube inner wall, have that suppress pressure big, suppress in wax deposition serious situation motionless, newly enter in oil pipe The problems such as water can not arranged.

Summary of the invention

In order to overcome existing on-line cleaning device to suppress, pressure is big, it is motionless to suppress when wax deposition is serious, and makes oil pipe The deficiency that the water inside newly entered can not arranged, the present invention provide a kind of tube inner wall hydraulic rotating on-line cleaning device, the tube inner wall Hydraulic rotating on-line cleaning device can fall by itself gravity, while falling the rotation of water conservancy power drive rotor and Scraper rotation is driven, the oil for wiping tube inner wall off is cured.The hydraulic pressure needed is small, and scavenging period is short, and driving water can pass through device Inside drives scraper, while water can reach the work of further cleaning tubing inner wall from outer wall and inside pipe wall gap to flowing down With.Bleeder or oil drain pump outflow oil pipe are finally driven the water through, and instead goes out well head from casing.

The technical scheme is that a kind of tube inner wall hydraulic rotating on-line cleaning device, including connector, outer cylinder, connector It is connected through a screw thread between outer cylinder, the outer cylinder right end is connected with scraper base, and the connector right end is equipped with nozzle, nozzle interior It is connected with the left end armature spindle of primary rotor, the right end armature spindle of primary rotor is connected to uropore and puts on, and primary rotor right end is logical It crosses armature spindle shaft coupling and is sequentially connected secondary rotor, three-level rotor, wherein three-level rotor right end is scraped by the connection of scraper shaft coupling Knife；It is provided with coupler bore road inside the connector, nozzle bore is provided on nozzle, uropore, which is put on, is provided with tail water set duct, scraper Scraper base duct is provided on seat.

The three-level rotor right end is sequentially connected several rotors, and the rotor of right end is scraped by the connection of scraper shaft coupling Knife.

The coupler bore road, tail water set duct, scraper base duct are axial direction, and the nozzle bore is spiral shape, and The hand of spiral is consistent with the primary rotor hand of spiral.

The invention has the following beneficial effects: (1), the tube inner wall hydraulic rotating on-line cleaning device is direct plungeed into oil pipe, It can fall by self gravity, unlike rubber cleaning means must just be walked downwards by hydraulic pressure；(2) water while falling Sharp power drive rotor rotates and scraper is driven to rotate, and the oil for wiping tube inner wall off is cured；(3) washer ensure that oil after passing through Inside pipe wall cleaning requirement, the water pressure needed is small, scavenging period is short, after the completion of cleaning water can from outer wall and inside pipe wall gap to It flows down, oil pipe is flowed out by bleeder or oil drain pump.

Specific embodiment

The present invention will be further explained below with reference to the attached drawings:

As shown in Figure 1, a kind of tube inner wall hydraulic rotating on-line cleaning device, including connector 1, outer cylinder 7, connector 1 and outer cylinder 7 Between be connected through a screw thread, 7 right end of outer cylinder is connected with scraper base 12.1 right end of connector is equipped with nozzle 2, and nozzle 2 is placed in In outer cylinder 7,2 inside of nozzle is connected with the left end armature spindle of primary rotor 4, and the right end armature spindle of primary rotor 4 is connected to uropore On set 5.4 right end of primary rotor connects secondary rotor 8 by armature spindle shaft coupling 6, and 8 right end of secondary rotor axis passes through another turn Sub- axis shaft coupling 6 connects three-level rotor 9, and 9 right end of three-level rotor connects scraper 13 by scraper shaft coupling 10, and the scraper 13 is set Inside scraper base 12, and blade shaft front end is fixed by locking nut 11.The primary rotor 4, secondary rotor 8, three-level turn 9 a power unit is collectively formed in son, and multiple power units can also be used in each washer, i.e., 9 right end of three-level rotor again according to The rotor of secondary several rotors of connection, right end connects scraper 13 by scraper shaft coupling 10.

It is provided with coupler bore road A inside the connector 1, nozzle bore B is provided on nozzle 2, is provided with tail water set on uropore set 5 Duct C is provided with scraper base duct D on scraper base 12.The coupler bore road A, tail water set duct C, scraper base duct D are axis To the nozzle bore B is spiral shape, and the hand of spiral is consistent with 4 hand of spiral of primary rotor.

Act sucker rod and plunger in oil well overhaul operation, and after opening underground bleeder or oil drain pump, by tube inner wall Hydraulic rotating on-line cleaning device is put into oil pipe, is just being suppressed by oil pipe, water flow is under differential pressure action from coupler bore road A Into being injected into primary rotor 4 through nozzle bore B, primary rotor 4 driven to operate, water flow is passed through from tail water set duct C outflow The circularly-supercharged acceleration of secondary rotor 8, three-level rotor 9 makes the wax and dead oil of 13 accelerated service of scraper cutting tube inner wall, finally Water flow is ejected from scraper base duct D, while having cleaning action to scraper 13, and then completes tube inner wall cleaning.
