Description
Technical field
The present invention relates to oil well technical field, be specifically related to a kind of multifunctional wellhead device.
Background technology
Owing to the height on well mouth of oil well distance ground differs, some well heads are less than ground, so oil well repairing operation rises
During lower tubing string, human users is the most inconvenient, often occur the problem that 1, well head height can not comply fully with ergonomics
Operate height normally, bring very big inconvenience to operator.2, during lower oil pipe, tubing coupling easily occurs with casing coupling inwall
Collide with and cause screw thread to damage, tubing coupling sometimes and plane collision on casing coupling, cause oil pipe to be threaded off or elevator touches with suspension ring
The accident such as hit occurs.3, after underground fracture, occurring packer not shrink or the accident such as sand card, well maintenance vehicle pulls out oil at process accident well
During pipe packer operation, several meters even tens centimeters sometimes can only be transferred to occur as soon as clamping stagnation, do not move up and down, well workover can only be used
Car applies certain upper lifting force amount to tubing string, continues upper lifting pipe post after packer decompresses, and period needs several hours the most several days,
Take well maintenance vehicle for a long time, it is impossible to continue other operations.If vehicle leaves, cannot shunt in a well, in fact it could happen that pass by one's way personnel or little
Child throws foreign material in well and causes second accident.
Summary of the invention
Present invention solves the technical problem that and be to provide a kind of multifunctional wellhead device, with run into during solving well workover
Above-mentioned technical barrier, reduces labor intensity, convenient working, minimizing vehicle holding time, ensures that lower oil tube is smooth and easy carries out.

Bottom is designed with female thread and is connected with described slip spider external screw thread, and described gland upper design has through hole, described three lobe conic clamps
Watt outer surface is that conical design is formed with described slip spider internal taper hole and coordinates, and described pressure ring is arranged on described gland and described three lobes
Between taper slips, described device jackscrew is fixed on wellhead casing pipe tubing string；Described device both can be high as well head
Degree adjusts and oil-tube lifting-correcting device, again can be as oil pipe hanging apparatus；Different rule only need to be changed on the basis of set of device
The taper slips of lattice can be achieved with well head height adjustment, oil pipe righting and the hanging function of pumping pipe string；
When as well head height adjustment and oil-tube lifting-correcting device, adjustment guide pipe is put into from top, adjust to properly
Operation height after tighten gland, described three lobe taper slips areThree lobe taper slips, real under gland tightens active force
Existing self-locking, stuck fast adjusts guide pipe；Not only greatly facilitate when using as well head height adjustment and oil-tube lifting-correcting device
Operative, alleviate labor intensity, and prevent collide with damage and the dropout etc. of tubing coupling and wellhead casing pipe box cupling
Accident occurs, and has ensured the safety of workover treatment process；
When as oil pipe hanging apparatus, described three lobe taper slips areThree lobe taper slips, above carry described oil pipe
Tubing string tightens gland after certain tonnage, and three lobe taper slips realize self-locking, stuck fast under described gland tightens active force
Oil pipe column, is suspended on tubing string on well head.When using as oil pipe hanging apparatus, not only solve and take well maintenance vehicle for a long time
The problem waited with personnel's operation, and the generation of the accident that can effectively prevent an accident.
Further, described adjustment guide pipe isAdjust guide pipe.
Further, described oil pipe column is 2-7/8 oil pipe column.
Further, the top of described adjustment guide pipe is designed with taper guiding surface, adjusts guide pipe inwall and oil
Pipe box cupling has about 10mm gap, and oil pipe enters to adjust along inclined-plane and enters in sleeve pipe under guide pipe, plays centralizing function, it is to avoid
Damage of colliding with between tubing coupling and casing coupling.
Further, described gland bottom is designed with female thread and is connected with slip spider external screw thread, makes three lobes in rundown process
Taper slips realizes self-locking, and upper design has through hole, so that adjustment guide pipe or oil pipe column pass from centre.
Further, described three lobe taper slips outer surfaces are that conical design coordinates with the formation of slip spider internal taper hole, in pressure
Realizing self-locking under lid screwing force effect, endoporus sawtooth tooth can adjust guide pipe or oil pipe column with stuck fast.
Further, described pressure ring is replaced by circular cover just to use as well mouth sealing device.
The invention has the beneficial effects as follows: the multifunctional wellhead device that present design provides can be according to well head practical situation
Need with operation, well head height is arbitrarily adjusted, to reach optimal performance height, facilitates operative；Can during lower oil pipe
So that oil pipe is carried out righting and guiding, it is to avoid damage of colliding with between tubing coupling and casing wall and casing coupling, it is ensured that under
Well operations is smooth and easy to be carried out, and improves work efficiency；During process accident, once occur packer clamping stagnation or sand card can not on move down
Dynamic, first this device can be contained on wellhead casing pipe box cupling, utilize well maintenance vehicle upper lifting pipe post to certain tonnage, then utilize this dress
Put and be suspended on the most stuck for tubing string on well head, it is possible to withdraw well maintenance vehicle, it is to avoid take for a long time；This device is in process accident
Being also used as sealed well lid during oil well to use, play sealing protection effect, a kind of device solves in workover treatment
Multiple problems.This device is the most easy to use, improve working performance and well workover quality, and has ensured workover treatment process
Safety, the problem not having professional wellhead assembly when solving workover treatment for a long time, can be as well head during workover treatment
Standard configuration, for improve workover treatment standardization have positive impetus.
