Specific implementation mode
In oilfield development process, it is often accompanied with wax deposition.It, will by the energy of oil reservoir itself especially in flowing well
Crude oil gives rise to ground from shaft bottom, gas stream from shaft bottom into well head migration process, oily wax is with temperature contained in crude oil
It constantly reduces and is gradually precipitated, be adsorbed on tube inner wall, pipe aperture is caused to reduce, reduce oil flow channel, lead to oil well
Liquid output declines, and increases inspection pump number, and pumping unit load increases, and increases energy consumption, and oil pipe, oil well production can be blocked when wax deposition is serious
Do not go out liquid, when more serious, rod broken can be caused, caused the accident.Therefore, it is necessary to remove the oily wax for being adsorbed on tube wall in time,
To ensure that pit shaft is unimpeded.
Usually, drifting operation is first carried out before wax removal.The purpose one of drifting be remove internal surface of sleeve pipe on adhere to consolidate
Body substance, such as slag, burr etc., second is that check the situation of run through casing size and deformation, breakage, third, formed after checking well cementation
Whether artificial bottom of a well meets formation testing requirement, fourth, the well killing fluid in adjustment well, complies with perforation requirement.Therefore, oily when drifting
An essential procedure before gas well pressure measurement operation.
Drifting mainly carries out drifting using jack rabbit component.Existing jack rabbit component includes the identical latus rectum of upper and lower diameter
Rule and the weighted lever that is connect with jack rabbit are connected with driving member above weighted lever, and driving member is connect by pulley with winch,
Driving member is discharged by winch, under the action of weighted lever gravity, so that jack rabbit is advanced and carries out drifting.
But since well inner sleeve junk, grease dirt, wax deposition are serious etc., it is stuck in well to be easy to cause jack rabbit, influences
Drifting operation.Be obstructed it is excessive be easy to cause driving member beat torsion break, fallen into well so as to cause tool or driving member, this to salvage
Work brings prodigious difficulty that can not even salvage, and the serious oil well that is likely to result in is scrapped.
For this purpose, a kind of jack rabbit component of the utility model offer and drifting device adopting, to overcome existing jack rabbit in drifting
It is easy the stuck technical problem of obstruction.
