Description
Technical field
The present invention relates to technical field of petroleum extraction more particularly to a kind of omnipotent slip systems of link-type taper.
Background technique
It requires to use slips in drilling well, oil recovery process to clamp drilling rod or oil pipe, then could execute promotion, decentralization
The movement of drilling rod or oil pipe, thus in drilling well, oil recovery process slips be it is essential, the safety and stability of slips are past
Toward the safety and stability for also determining drilling well, oil recovery.So safe and stable slip system is just extremely important.
There are mainly two types of slips used in drilling well at present, oil recovery process, one is hydraulic cylinder control reciprocating slips,
The clamping force of slips is provided by the thrust of hydraulic cylinder, the advantages of such slips is to be able to achieve the clamping of upper and lower both direction, but lack
Point, which is that oil cylinder is larger, causes slips overall volume larger, and manufacturing cost is higher and safety is lower, if sent out in use
Raw hydraulic oil leakage, slips can lose clamping force immediately.Another kind is link-type taper slip system, by a small oil tank push-and-pull
The advantages of connecting rod realizes the clamping of slips or loosens, and the clamping of slips is realized by taper slip spider, such slips be volume compared with
Small manufacturing cost is lower, and can be realized self-locking, even if generation hydraulic oil leakage after slips clamps during the work time
Clamping of the slips to drilling rod or oil pipe is not influenced, but the disadvantage is that can only realize the clamping in a direction.
In order to make slips more secure and reliable in drilling well, oil recovery process, people are often superimposed upon one using by two slips
The method used is acted, hydraulic reciprocating type slips one taper slips of superposition or two taper slips are superimposed and make
With or two hydraulic reciprocating type slips be superimposed use, do so the security reliability for improving slips work really.
Wherein, most safe and reliable is that two taper slips are superimposed the mode used, and a taper slips is used for drilling rod or oil
The anti-top of pipe or pushing, taper slips are above mentioned for drilling rod or oil pipe, and either drilling rod or oil pipe are above mentioned or pushed
Or anti-top can be taken into account, and because of the latching characteristics of taper slips, even if hydraulic, card is lost after slips clamping at work
Watt drilling rod or oil pipe can be also clamped very well, securely and reliably.
But the usage mode of this slips combination is safe and reliable not enough, because the taper slips of the two superpositions is only each other
It is vertical, it needs to operate respectively in operation.Underground working is extremely complex in drilling well, oil recovery process, especially in drilling process
In, blowout can may occur at any time, it is also possible to well pressure will disappear at any time, under the underground working of this complexity, two tapers
The mode of slips superposition require to drilling rod or oil pipe clamp or release each time will safety action execute in place, if worker
Neglected in operation, lead to being not turned on for two independent taper slips unlatchings, the closing without closing
It closes, then very serious accident may occur.

It will not fall easily.
When work, it is coupled in first hydraulic cylinder and second hydraulic cylinder using the same oil circuit, when first hydraulic cylinder
When piston rod and second hydraulic cylinder piston rod stretch out, the first push rod 21 drives first connecting rod 221 and second connecting rod 231 to rotate, the
One connecting rod 221 drives first rotating shaft 222 to rotate, and first rotating shaft 222 drives the rotation of the first driving lever 223, drives 24 court of the first slips
It is moved to the first taper hole, same second slips 25 is moved towards the second taper hole；Third slips 34 and the 4th slips 35 are pushed away second
Under the action of bar 31, third slips 34 is moved towards the first taper hole, and the 4th slips 35 is moved towards the second taper hole, thus, it realizes
Clamp the clamping of drill bit or oil pipe；When the piston rod of first hydraulic cylinder and second hydraulic cylinder piston rod retract, the first slips 24
Move with third slips 34 to far from the direction of the first taper hole, the second slips 25 and the 4th slips 35 are to the side of separate second taper hole
To movement, to unclamp drill bit or oil pipe.
Drilling rod or oil pipe can be carried out in upper and lower both direction simultaneously by control first hydraulic cylinder and second hydraulic cylinder
Clamp or release, fault-tolerance is higher, can effectively prevent maloperation.
When slip system needs to open, underlying second slips 25 is affected by gravity, and can successively make second
Driving lever 233, the second shaft 232, second connecting rod 231 have an anticlockwise torque, this torque by the first push rod 21 according to
It is secondary to be transmitted to the first connecting rod 221 being connected above with the first push rod 21, first rotating shaft 222, the first driving lever 223, finally it is transmitted to
First slips 24 of top, and the quality of the first slips 24, the second slips 25 is the same, so when slip system needs to open
When, the piston rod of first hydraulic cylinder retracts, and the active force of first hydraulic cylinder is only required to overcome the frictional force between machine driving
, therefore first hydraulic cylinder can be made small, save cost and power source.Similarly, third slips 34 and the 4th is driven
The second hydraulic cylinder of slips 35 can also be made small.
Similarly, when slip system needs to hold tightly drill bit or oil pipe, the piston rod of first hydraulic cylinder stretches out, and above first
Slips 24 will drive following the second slips 25 by gravity and hold drill bit or oil pipe tightly, and third slips 34 is also able to drive the
Four slips 35 hold drill bit or oil pipe tightly.This slip system links together the first slips 24 and the second slips 25, third slips
34 link together with the 4th slips 35, make their timing synchronization movements, and can reduce active force by mutual gravity, complete
At movement, cost and power source are saved.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating examples made by the present invention, and being not is pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., is all contained in the claims in the present invention within the spirit and principle of invention
Within protection scope.
