Description
Technical field
It the utility model is related to petroleum industry oil, the wellhead assembly of gas and water well, particularly wellhead assembly lumen loading fill
Put, used when workover treatment removes the oil gas water well down-hole string equipped with instruments such as packer, anchoring devices.
Background technology
Packer, slips, back-off packer are the critical components connected in oil, gas and water well down-hole string.Especially packer
Packing element can hydraulic pressure, mechanical thrust effect under, acted on by axial compressive force on casing wall, sleeve pipe sealed,
In, the separate zone production of deep oil well, water blockoff, pressure break, play a role in the operation such as water filling, be underground common tool.In recent years, it is oily
Well has been enter into high water cut stage, and plus the needs of new oil production method thermal recovery, hole condition deteriorates increasingly.Original packing element is resistance to
Temperature is mostly at 120 DEG C, in the construction of every technological measure, can not meet the needs of oil field drilling.Hot-producing high-temp to insulate
The rubber of device easily comes off, and causes the jam situations such as rubber card, sand washing card, drifting resistance, perforation resistance, is delayed the normal of next procedure
Construction, improves construction cost, adds material consumption, have impact on the economic benefit of enterprise.
The block teeth of packer, coming off for rubber are occurred mainly near well head, because the inner chamber of well head four-way, blowout preventer is remote
Much larger than the diameter of well inner sleeve.The part that is scattered being attached in well on instrument, when playing tubing string in well, due to the limit of casing inner diameter
System follows tubing string up together；When near to well head, the internal diameter of wellhead assembly increases suddenly, the part that is scattered lose limitation fall well and
Cause the accident.In order to overcome above mentioned problem, in the job execution for acting down-hole string, the measure being usually taken is in tubing string
Packer, anti-jack slips are when mentioning well head soon, the wellhead assembly such as preventer and big four of well head of dismantling installation, wait to propose envelope
The wellhead assemblies such as big four, blowout preventer are loaded on after the downhole tools such as device.This settling mode, first, not meeting well control safety
Regulation, second, considerably increasing the labor intensity of worker, have impact on efficiency of construction.If big four, blowout preventer etc. can not laid down
Wellhead assembly, it there is the part that is scattered such as rubber and block teeth and fall the risk of well.Therefore production scene is badly in need of a kind of not removing greatly
The wellhead assemblies such as four-way, blowout preventer also can guarantee that the part that is scattered of downhole tool does not fall the device of well.
The content of the invention
The purpose of this utility model is manufacture wellhead assembly lumen loading device, changes the internal diameter of wellhead assembly, makes in well
The instrument with the part that is scattered such as packer in the case where not removing wellhead assembly, also can smoothly propose well head, allow and be scattered
Part will not fall well in well head, reduce the generation that part falls well accident, improve operating efficiency, reduce production cost.
What the utility model was realized in：Wellhead assembly lumen loading device includes cylinder and guide ring, cylinder and leads
It is the arc bodies of two engagements to ring, the upper end of cylinder is threadedly coupled with pressing plate, lower end and guide ring weld, the external diameter of cylinder
It is consistent with the internal diameter of wellhead assembly.
It is of the present utility model significantly using effect be：The utility model is simple in construction, will be wrapped with the down-hole string of the present apparatus
Down in well, the present apparatus is located in the inner chamber of wellhead assembly, change the internal diameter of wellhead assembly, be allowed to outer with down-hole string
Footpath is consistent.When downhole tool goes upward to wellhead assembly, because the inner chamber of wellhead assembly is big the part that is scattered on instrument will not be made to exist
Well head is fallen into well, ensure that in well the instrument normally rountrip in the present apparatus, it is therefore prevented that because caused by spatial variations in well
Junk.The probability that the part that is scattered falls well in well head is effectively reduced, avoids the risk of well accident, substantially increases work
Industry efficiency, significantly reduces production cost.The present apparatus is easy to operate, avoids and removes the cumbersome processes such as wellhead assembly, meets
Well control safety provides, ensure that construction safety, improves the actual effect of construction, significantly reduces the labor intensity of worker, has aobvious
The economic benefit and social benefit of work.
Brief description of the drawings
Fig. 1 is the utility model structure chart.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing, not limits the scope of protection of the utility model.It is as described below to be only
Preferred embodiment of the present utility model, other equivalence changes drawn with the utility model, it all should belong to of the present utility model
Protection domain.
Referring to Fig. 1, wellhead assembly lumen loading device includes cylinder 6 and guide ring 8, and cylinder 6 and guide ring 8 are two
