Description
Technical field
The utility model belongs to petroleum and natural gas drilling-production equipment technical field, is related to a kind of suitable for workover treatment with pressure
Auxiliary remove tube apparatus.
Background technology
During development of fields, such as encounters strata pressure variation, down-hole accident, changes mining type, technique skill
Situations such as art, adjustment Development layer series, generally requires to carry out workover treatment.Oil well repairing operation refers to release the event of oil/gas well
Barrier, ability of resuming production, and being transformed to oil reservoir improve oil gas capacity of well, to obtain the economic benefit of bigger
The operation process of tripping in or frequent, repeatedly the maintenance and repair of replacement flow string into oil/gas well or well casing.
Three kinds of oil-water well upkeep operation generally use open flow, kill-job and Operating Pressure operating types.If using open flow
Pressure release, not only waste of resource, destroys strata pressure balance, can also ground environment be caused to pollute, increase duty cycle；And it is pressed
When well operations, well killing fluid contacts stratum, causes stratum filtration channel blockage, pollution stratum, finally influences recovery ratio.Not injure
Stratum keeps stratum energy, shortens duty cycle, reduces environmental pollution, this set workover rig and method are based on Operating Pressure skill
Art.Operating Pressure is primarily referred to as during the workover treatment in well site, and high-pressure water injection well is without kill-job and open flow the case where
Under, controlling the pressure in well with Operating Pressure blowout hookup so that band press liquid will not be revealed, and not generate blowout,
In the case that such with pressure, the high-efficient homework mode of raising and decentralization is carried out to tubing string.
A most important and most heavy link has been exactly lower tubular column in all kinds of well workovers and well stimulation operation.Play down tube
Column refer to using associated mechanical tool by well tubing string propose well head, unload and be placed on oil pipe bridge by root, through over cleaning, zhang
Amount assembles and replacement is gone into the well after tool, then by the process of root G.I.H again.This work usually accounts for entire well-repairing work amount
80% or more, and labor intensity is big.Since China major part oil field has been enter into the exploitation intermediary and later stages, the difficulty of oil recovery is more next
Bigger, well workover task is also more and more heavier.Especially west area, oil well is relatively deep, natural environmental condition is very harsh.It improves
Well workover efficiency, the labor intensity for mitigating worker, make worker as possible far from severe working environment, it is desirable to have the well of superior performance
Mouth removes column apparatus.
Mainly tubing string is clamped by removing column apparatus in workover treatment with pressure, overcomes clips clamp force with down-hole pressure to oil
The upper top power of the generations such as pipe, sucker rod, tool, can rise out safely or tripping in.Traditional auxiliary, which removes tube apparatus, to expire
Foot straps press the elemental operation requirement of well workover system, but there are clearly disadvantageous places.The first, hydraulic stem moves back and forth once
In the process, effect stroke, an idle stroke backhaul, operating efficiency be not high there are one；The second, due to some tubing strings since breakage is passed through
Blocking reparation causes tubing string length to differ, and is only clamped in box cupling edge there are slips during this remove and leads to down-hole high pressure
The dangerous situation that tubing string is ejected.

When the cylinder rod outer end of cylinder 8 touches part lower stroke switch, lower tubular column clamping device 6 clamps tubing string, then upper tubing string
Clamping device 3 unclamps tubing string.Lower tubular column clamping device 6 is clamped tubing string and starts to move down to initialization position, while upper tubing string
Clamping device 3 moves upwardly into initialization position in the state of not clamping tubing string.
2.4) in period of the upper tubing string collar finder 2 without detection signal, step 2.2) and step 2.3) are repeated.
2.5) when upper tubing string collar finder 2 detects that string collar sends out detection signal, upper and lower tubular column clamping device
Successively respective initial position is returned to respectively.This process includes two kinds of situations：
A. tubing string state is clamped when upper tubular column clamping device 3 is in, when lower tubular column clamping device 6 is in releasing orientation, under
Tubular column clamping device 6 clamps oil pipe after being first moved to initial position, and then upper tubular column clamping device 3 is in the state for not clamping tubing string
It is moved to initial position.
B. tubular column clamping device 6 is in clamping tubing string state instantly, when upper tubular column clamping device 3 is in releasing orientation, on
Tubular column clamping device 3 clamps oil pipe after being first moved to initial position, and then lower tubular column clamping device 6 is in the state for not clamping tubing string
It is moved to initial position.
2.6) it repeats step 2.2) and step 2.3) continues running string operation, until the dead weight of tubing string can overcome well
Pass hull closure after the pressure of lower oil gas.
By the above-mentioned course of work it is found that auxiliary, which removes tube apparatus, is proposing that the process of tubing string and running string is all not present
Idle stroke is, it can be achieved that efficiently play lower tubular column operation, and after detector detects box cupling, the tubular column clamping device of equipment can be stood
It successively moves to initial position and then carries out circulation action, it is ensured that tubular column clamping device will not be clamped to box cupling, eliminate peace
Full hidden danger.
