Abstract
The utility model discloses a kind of for assisting the blowout hookup of shackle, which includes blowout-prevention control device and oil pipe hanging apparatus.The blowout-prevention control device is made of rotating blowout preventer, raising pipe nipple, oil recovery four-way and pressure relief opening；The oil pipe hanging apparatus is made of two semicolumns, connecting plate, screw and oil recovery four-way.Implement the utility model, internally when stifled oil pipe shackle, so that the fluid sprayed in oil pipe becomes controllable state, while can also be released safely the high-pressure fluid in device by pressure relief opening.Device assembling is simple, easy to operate.
Description
Technical field
The utility model belongs to oil/gas well security technology area more particularly to a kind of for assisting the blowout hookup of shackle.
Technical background
The necessary channel that oil pipe is produced as petroleum, natural gas, if there is oil pipe when oil/gas well production or workover treatment
Blocking, not only influences the normal production of gas well, but also very big security risk can be also brought along to workover treatment.
By corrosion inhibiter type selecting be lack of pertinence with live hole condition bad adaptability, cause corrosion inhibiter that degradation or heavy occurs in underground
It forms sediment；The underground foul not drained in drilling well, Completion Operations；Downhole corrosion product；And upper wellbore is because of gas flow temperature decline shape
It can all cause to block up in oil pipe at reasons such as hydrates.During well workover, due to do not know oil pipe in block up position and
Pressure size in blocked oil pipe has in a flash high-pressure fluid ejection after dismantling the oil pipe to build the pressure, can not only cause
Casualties, environmental pollution, more likely induced flow is so as to cause blowout out of control.
Be directed to spray in oil pipe at present, common practice be using easy blowout prevention box, after the method can be reduced oil pipe shackle,
Inside there is the ejection of low-pressure fluid, if but high pressure has been suppressed in oil pipe, it cannot but play an effective role in the control.
Utility model content
The utility model discloses a kind of for assisting the blowout hookup of shackle, overcomes and occurs at present, builds the pressure in oil pipe
Shackle and the safety problem that generates afterwards, are not required to complicated processing technology, can quickly be mounted on well head or rig floor, reduction is repaired
The risk of well operations.
The utility model is realized in this way: it is a kind of for assisting the blowout hookup of shackle, it is characterised in that: the device by
Blowout-prevention control device and oil pipe hanging apparatus are constituted, device assembling sequence from top to bottom are as follows: rotating blowout preventer, increase it is short
It connects, oil recovery four-way；
The blowout-prevention control device is made of rotating blowout preventer, raising pipe nipple, oil recovery four-way and pressure relief opening；
The boll-weevil hanger and oil recovery four-way that the oil pipe hanging apparatus is made of two semicolumns, connecting plate and screw
Composition；
The boll-weevil hanger is seated among oil recovery four-way.
The space increased between pipe nipple and oil recovery four-way constitutes the inner cavity of high-pressure fluid in oil pipe after discharging shackle.
The pressure relief opening is cooperatively connected by one of top wire hole on oil recovery four-way with variable buckle connector, after shackle
The high-pressure fluid of generation excludes safely through pressure relief opening.
The beneficial effects of the utility model are: variable buckle and oil pipe hanging apparatus processing technology are simple, blowout-prevention control device can
Off-the-shelf gear direct-assembling is directly used, construction is simple, easily and fast, Meteorological is low, reduces construction risk.
Detailed description of the invention
Attached drawing 1 is the schematic diagram that the present invention assembles rear pressure release state.
Attached drawing 2 is the structural schematic diagram of the boll-weevil hanger in the present invention.
Attached drawing 3 is the structural schematic diagram of the variable buckle connector in the present invention.
In figure: 1- rotating blowout preventer, 2-, which is increased, to be shorted, 3- oil recovery four-way, 4- pressure relief opening, 5- semicolumn, 6- connecting plate, 7-
Screw, 8- top wire hole, 9- variable buckle connector, 10- boll-weevil hanger, 11- oil pipe.
Specific embodiment
The embodiments of the present invention are further described with reference to the accompanying drawing:
1. assembling, as shown in Figure 1, blowout-prevention control device is by rotating blowout preventer, raising pipe nipple, oil recovery four in the utility model
Steel ring sealing, flange, bolt fastening are crossed all；Variable buckle is threadingly attached to the top wire hole of oil recovery four-way, after connection fastening is good
It is seated on rig floor.
2. well mouth oil pipe is finally seated on the rotating blowout preventer of the device by well head of exchanging by winch and tourist bus.
3. shackle, above mentioning oil pipe makes the 1st oil pipe all propose rotating blowout preventer recoil elevator, will be seated at using hydraulic tongs
Hoop on rotating blowout preventer release 2-3 button；Above mentioning oil pipe again makes second oil pipe propose rotating blowout preventer completely, at this time by two
A separated oil pipe hanging apparatus is stuck on the tube body of the 2nd oil pipe, and is connected the device by 4 connecting plates and 8 screws
It is connected in an entirety；Then drain line is descended, the seat that suspension arrangement brings oil recovery four-way into is hung position by oil pipe, under oil pipe continues
The hoop of final 2nd oil pipe of row is seated at oil pipe hanging apparatus, at this time official seal spray apparatus, then uses hydraulic tongs shackle.
4. pressure release slightly above mentions oil pipe and fills by the high-pressure fluid in oil pipe in raising pipe nipple and oil recovery four-way after the completion of shackle
Between formed have in inner cavity, then by the pressure relief opening at jackscrew, release chamber using pipeline and the valve control connected
Interior pressure.
5, preventer is opened, is above detained again after make-up, second oil pipe is proposed into preventer and takes down the oil pipe suspension taken out of
Device is spare, and lays down the 1st oil pipe of pressure release again, to complete shackle operation.
Claims (3)
