Description
Technical field
The present invention relates to oil field Paraffin Removal equipment technology fields, and more specifically, the present invention is a kind of producing well wax removal dress
It sets and method.
Background technique
Containing the paraffin of different number in crude oil, under reservoir condition, it is typically in dissolved state, crude oil rises from shaft bottom
When flowing through oil pipe, temperature, pressure are gradually decreased, and wax is gradually precipitated, and aggregation, product invest tube wall, claim oil well paraffinication, it makes in oil pipe
Diameter becomes smaller, and influences capacity of well, so that oil well is stopped production when serious.
The widely used method for removing tube wall product wax has two on the market at present: one is mechanical paraffin removal, another kind is heat
Power wax removal there is also with electrothermal way or thermochemical method wax removal, but is rarely employed in China, and wherein mechanical paraffin removal is applied to
Oil flow production well, gas-lift production well and pumpingh well, but the mechanical paraffin removal device of discovery at present on the market is all in use
It is fixed size, that is, size is fixed when being put into and taking out, therefore equipment is being placed into oil in use
When well casing, device bottom can will accumulate wax and scrape from tubing wall, so that long-pending wax is fallen in oil pipe bottom, therefore accumulate wax also when being exploited
It can be deposited in again tube inner wall with oil liquid, cause tube inner wall product wax meeting rapid accumulation, influence exploitation rate again.
Therefore, a kind of producing well paraffin removal unit that can tube inner wall product wax removed and is discharged is needed.
Summary of the invention
In order to overcome the drawbacks described above of the prior art, the embodiment of the present invention provides a kind of producing well paraffin removal unit and side
Method can pass through not of uniform size realize when disengaging and remove tube inner wall product wax, and inner product wax is taken out of by equipment
Producing well paraffin removal unit.
To achieve the above object, the invention provides the following technical scheme: a kind of producing well paraffin removal unit, including cylinder and company
Connect column, the top of the cylinder integrally formed with lifting ring, the outer surface of the cylinder integrally formed with three row's scraper plate fixed blocks,
The inside of the scraper plate fixed block is fixedly installed with scraper plate limit integrally formed with scraper plate limit plate on the inside of the scraper plate fixed block
Position axis, the inner cavity of the scraper plate fixed block are movably installed with scraper plate, and the bottom end of the cylinder and the top of connecting column are welded, described
The bottom end of connecting column is fixedly installed with collection fixing axle, and the bottom end for collecting fixing axle is described broken integrally formed with broken wax pyramid
The outer surface of wax pyramid is fixedly installed with collection fixed block, and the inside for collecting fixed block is limited integrally formed with umbrella fixing axle is blocked
Plate is fixedly installed on the inside of the collection fixed block and blocks umbrella fixing axle limit shaft, the inside activity peace for blocking umbrella fixing axle
Equipped with umbrella fixing axle is blocked, the bottom for collecting fixing axle outer surface, which is fixedly installed with, thickens ring, and the side for thickening ring is living
It is dynamic be socketed with it is non-porous block umbrella, the non-porous inside for blocking umbrella is fixedly mounted with the outer surface for blocking umbrella fixing axle, described non-porous to block umbrella
The outer surface of bottom end, which is fixedly installed with, blocks umbrella fixed ring.
In a preferred embodiment, the three rows scraper plate fixed block is evenly distributed on the outer surface of cylinder, and every
There are four scraper plate fixed block, four scraper plate fixed blocks to be evenly distributed on cartridge outer surface by row, and adjacent two rows of scraper plate fixed blocks
It is set as 30 ° of rotation.
In a preferred embodiment, the scraper plate is set as sector compatible with oil well inner wall, and scraper plate two sides
The angle on side is 36 °, and upper row scraper plate and the scraper plate of next row adjacent locations overlap when being installed, and is overlapped angle
It is 3 °.
In a preferred embodiment, the scraper plate limit plate and scraper plate limit shaft are located at the interior of scraper plate fixed block
Side, and scraper plate is installed between scraper plate limit plate and scraper plate limit shaft.
In a preferred embodiment, the broken wax pyramid is set as coniform, and broken wax pyramid is top down.
In a preferred embodiment, described to block umbrella fixing axle limit plate and block umbrella fixing axle limit shaft positioned at collection
The inside of fixed block, and block after blocking umbrella fixing axle and being installed umbrella fixing axle and be located to block umbrella fixing axle limit plate and block umbrella and fix
Between axis limit shaft.
A kind of application method of producing well paraffin removal unit, comprising the following steps:
S1. it determines the position using equipment and transports to equipment using position；
S2. the device is connected on cable by scraper plate fixed block, and equipment is placed into inside oil pipe by oil well mouth, so
Slowly slack off afterwards, scraper plate and block umbrella fixing axle will under the action of oil pipe inner product wax, oil liquid and tube inner wall, scraper plate with
Scraper plate limit shaft is in contact, and blocks umbrella fixing axle and contacts with umbrella fixing axle limit shaft is blocked, and the broken wax pyramid on top can guarantee that equipment exists
The position for having oil liquid in oil pipe smoothly glides；
S3. when equipment transfers to certain position, start slow drawing device, then scraper plate will under the action of oil liquid with scrape
The contact of plate limit plate, while oil liquid acts on non-porous block and to block umbrella fixing axle on umbrella and be in contact with umbrella fixing axle limit plate is blocked,
When scraper plate is contacted with scraper plate limit plate, the end of scraper plate fits with tube inner wall, and then three layers of scraper plate can will be in oil pipe
