Description
Technical field
The present invention relates to a kind of paraffin removal method, and in particular to the method for striking off crude oil conduit wall wax layer.
Background technology
Drilling well is to utilize plant equipment, and stratum is drilled to the engineering of the cylindrical orifice with certain depth.It is broken by rock
Broken mode and used tool type, can be divided into percussion drill and rotary drilling again.
Percussion drill, also known as impact drill.Cable tool bit is sent to shaft bottom with steel wire rope, by power drive walking beam mechanism, makes walking beam
One end moves up and down, and drives percussion above and below steel wire rope and drill bit generation, makes catalase.Percussion drill drilling speed is slow, and efficiency is low,
Not adapting to well depth increasingly increases the drilling requirements with bad ground, is gradually replaced by rotary drilling.But it has equipment simple, cost
It is low, not the advantages of polluted reservoir, low pressure Oil/gas Well, the absorption well shallow available for some etc..
Rotary drilling is to utilize the cutting produced during bit or abrasive action fractured rock.It is current most general drilling well
Invention.It is faster than percussion drill drilling speed, and it is easily handled the complex situations such as well slough, blowout.By power delivery mode, rotary drilling can be divided into again
Rotating disk is bored and two kinds of underground power drilling：Rotating disk is drilled in device rotating disk at the well head of rig floor, and center of turntable part has on square hole, drill string
The kelly bar at end passes through and connects drill string and drill bit under the square hole, kelly bar, drives drill string and drill bit to revolve together during power drive rotating disk
Turn, fractured rock.Underground power drilling is to drive drill bit fractured rock using mud motor, and drill string is not rotated during drilling, mill
Damage small, service life long, be particularly suitable for digging a directional well.Well dynamic is drilled with turbine brill, screw drill and electric drill etc..
The crude oil of some places is high due to the content of wax, and oil well paraffinication phenomenon is serious.Oil well paraffinication can cause crude oil circulation passage
The problems such as reduction, oil pressure rise, oil pipe blocking.Wax deposition can also make the excessive burning pump of electric pump load, finally result in the crude oil underproduction even
Stop production.
The content of the invention
Present invention aims at the method that crude oil conduit wall wax layer is struck off in offer, the crude oil of some places is solved due to the content of wax
Height, causes oil well paraffinication, the problem of causing the reduction of crude oil circulation passage, oil pressure rise, oil pipe blocking.
The present invention is achieved through the following technical solutions：
The method for striking off crude oil conduit wall wax layer, comprises the following steps：
Step A prepares：Winch is fixed on beside oil well, fixed wheel is fixed on above oil well import, one end of steel wire rope with
Winch is connected, and the other end of steel wire rope is bypassed after fixed wheel and is connected with one end of connecting shaft；
Step B paraffin cuttings：Start winch, steel wire rope is lengthened, so that except wax component falls along oil well diameter；
Start drive device I and drive device II simultaneously, drive device II makes scraper be rotated around the axis of support tube, with
Wax layer on the borehole wall is scraped；Drive device I makes doctor assemblies be rotated around connecting shaft, and the wax layer of a circle of the borehole wall is scraped
Remove；
Step C is exited：Start winch, steel wire rope is received short, will be exited except wax component from oil well.
The wax component that removes includes connecting shaft, supporting plate, doctor assemblies, drive device I, drive device II and the company of being set in
Mounting cylinder in spindle, one end of the connecting shaft is connected with supporting plate, and connecting shaft axis perpendicular to supporting plate, the drive
Dynamic device I is located in supporting plate, and energy drive installation cylinder is rotated around the axis of connecting shaft；

II driving support tube is rotated around oneself axis；Several scrapers, the knife of the scraper are provided with the side wall of the support tube
Axis of the sword parallel to support tube.
It will be put into by suspension apparatus except wax component in the oil well for needing paraffin removal, then start drive device I, drive device
II, when scraper is around supporting cylinder axis rotation, scraper strikes off the wax on wall, and with the startup of drive device II, scraper group
The overall axis around connecting shaft of part is rotated, so that the wax that scraper encloses the borehole wall one strikes off；Simultaneously in the effect of suspension apparatus
Under, except wax component is moved along oil well axis, the wax on oil well wall is removed, and then avoid the reduction of crude oil circulation passage, oil
The generation of the negative aspects such as rise, oil pipe blocking is pressed, to ensure that normally circulation and oil extraction are smoothed out crude oil.
Further, the support shaft bends to C-shaped, and its end is connected with the side wall of mounting cylinder, the support tube position
In in support shaft away from mounting cylinder axle portion on.
Further, the cross section of the scraper is triangle, and its base is connected with support tube, and its stringcourse is arc,
And one stringcourse inner concave towards the center of the triangle, the center of the inner concave of another stringcourse dorsad triangle.By scraper
Section set triangularity, and two stringcourses be camber line, the wax layer on wall is struck off beneficial to scraper.
Further, support bar coaxial to one another and splicing bucket are provided with the lower surface of the supporting plate, it is described
Support bar and connecting shaft coaxial line, one end of support bar and the lower surface of supporting plate are connected, the other end and splicing bucket of support bar
The connection of bucket bottom, the opening of the splicing bucket is towards supporting plate.
