Abstract
The invention provides a novel hydraulic-controlled automatic slip. The novel hydraulic-controlled automatic slip is characterized by mainly comprising a transmission plate, an inner liner plate, an outer wall, a seat, a pulling rod, a slip body, teeth, a hydraulic cylinder, a supporting rod and a connecting bolt; the seat is fixed to a wellhead device of an oil well through a bolt hole in the lower part, a pipe column is clamped through a parallelogram mechanism according to the self-locking principle, then the hydraulic cylinder pushes the transmission plate to drive the slip body to move, so as to release the pipe column, and as a result, the function of positioning and releasing the pipe column is realized. The hydraulic-controlled automatic slip has the beneficial effects that the function of the slip of automatically clamping and releasing the pipe column is innovatively realized according to the self-locking principle, and therefore, the working efficiency and the working safety are improved; the design of a taper surface of the traditional slip is removed, thus the structure is simple, and the processing and manufacturing are easily carried out; the teeth are mounted in the slip body, which effectively increase the friction between the slip and the pipe column, and therefore, the radial force applied to the pipe column is reduced, and as a result, the pipe column is avoided pressure damage.
Description
Technical field
The automatic clamping device of tubing string in lower tubular column process is played when the present invention relates to petroleum industry drilling well or workover treatment.
Background technology
In petroleum industry, in drilling well or well workover process, need tubing string (drilling rod, oil pick-up tube, sucker rod and sleeve pipe etc.) one one to transfer in oil well, when needing, also will by the taking-up oil well of one root one.In the process playing lower tubular column, need slips to be sat by the tubing string stayed after shackle in oil well and be placed on well head, in order to avoid tubing string falls into well.Traditional slips is manual operation, and it works under hard conditions, and dangerous high, operating efficiency is lower.
The present invention proposes brand-new slip design principle, change the design of the inner conical surface of traditional slips, make the structure of slips more simple, be convenient to processing.Have employed Driven by Hydraulic Cylinder, operating principle is simple, and reliability is high, achieves the automatically working of slips simultaneously.By changing connector, can realize the clamping work of the tubing string of different size, versatility is good.With tubing string contact portion, slip insert structure is housed, effectively can increases friction, reduce the axial compression to tubing string, protection tubing string is not damaged.
Summary of the invention
The present invention is directed to weak point when legacy card bricklayer is done, propose a kind of brand-new hydraulic control automatic power slips.
A kind of novel hydraulic controls automatic power slips, it is characterized in that: form primarily of drive plate, interior lining panel, slips outer wall, slip spider, pull bar, slips body, slip insert, hydraulic cylinder, support bar and connecting bolt.Wherein slip spider can be fixed on the wellhead assembly of oil well by the bolt hole of bottom, and slips outer wall is bolted to be fixed with slip spider, and interior lining panel is positioned at the inside of slips outer wall, is connected with slips outer wall with bolt.The inwall of interior lining panel is welded with bolt Mounting Earrings, connect slips body by 3 groups of bolts, slips body and interior lining panel form parallel-crank mechanism, can be up and down.Slips body is made up of 3 identical cirque structures, the inside stationary slip tooth of slips body.Drive plate is connected with slip spider by hydraulic cylinder, and the lower surface of drive plate connects 3 slips bodies by pull bar, and under the effect of hydraulic cylinder, drive plate drives slips body to move up and down by pull bar.
Connecting rod has different size design, obstructed connecting rod can be selected to carry out work according to the thickness of tubing string, to meet different conditions of work.

Detailed description of the invention
The seat that hydraulic control automatic power slips mainly completes tubing string in oil well in the operating process that tubing string removes puts the work of well head, avoids tubing string to fall into oil well.1-3 by reference to the accompanying drawings, the invention will be further described:
Hydraulic control automatic power slips has clamping tubing string at work and unclamps tubing string two courses of work, and hydraulic control automatic power slips is fixed on the wellhead equipment of oil well by slip spider (4).During clamping tubing string, hydraulic cylinder (6) does not apply any active force to drive plate (1), after tubing string puts into slips body (7), after the gravity of tubing string self and the downward activity of frictional force between tubing string and slip insert (8), under the effect of support bar (9), by self-lock mechanism, tubing string is clamped.
When unclamping tubing string, hydraulic cylinder (6) applies thrust upwards to drive plate (1), drive plate (1) moves upward, slips body (7) is driven to move upward by the connecting rod (5) of bottom, under the effect of the parallel-crank mechanism of the common composition of slips body (7), interior lining panel (2) and support bar (10), slips body (7) upwards and backward moves simultaneously, be separated with tubing string, thus unclamp tubing string.
Useful achievement of the present invention is: achieve the automatic clamping function in the slips course of work, change Traditional Man operation mode, novelty achieve slips function by self-lock mechanism, improve the safety of operating efficiency and work.Abandoned the conical surface design in traditional slips, structure is simple, is easier to processing and manufacturing.By changing connector, can realize the clamping work of the tubing string of different size, versatility is good.Slips body is installed slip insert and effectively increase friction between slips and tubing string, reduce the radial load that tubing string is subject to, protection tubing string is from stress injury.
