Technical field
The present invention relates to a kind of paraffin removal equipment, and in particular to petroleum drilling takes oil well de-waxing apparatus.
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
