Description
Technical field
The present invention relates to drilling tool technical field, is a kind of drilling well chuck.
Background technology
In Process of Oil Well Drilling, for more bit change, well logging or setting of casing drifting, it is necessary to by thousands of meters in well of drilling tool
It is proposed, G.I.H again after more bit change, well logging.In operation process, driller stands beside boring winch, a hand steered brake handle,
Clutch switch is pushed away on the other hand, controls travelling block put-on and delegated drilling tool, two spudders, which are kept beside well head, detain, unloads
Detain, remove elevator operation.During lower brill, driller lifts brake handle, and elevator of the travelling block suspended from drilling tool is transferred together with drilling tool
To well head, rotating disk is seated at, two spudders extract the lock pin of elevator both sides, pull out suspension ring, the another being pushed into beside rotating disk
In the hanger of elevator, lock pin is inserted, upper travelling block to quadruple board platform, the frame work that carry of driller pulls open elevator valve, be buckled in another cylindrical drill
On tool, lift, and well head drilling tool make-up, after upper button, lift drilling tool, open the elevator valve on turntable surface, move to beside rotating disk,
Drilling tool is transferred to well head, rotating disk is seated at, so moves in circles, put another cylindrical drill tool.In this link, the hanger opening of elevator
Less than 100mm, driller can not possibly be not in place, it is necessary to continue to transfer if early stop just in turntable surface brake tight braking；It is if late
Stop, suspension ring can withstand ear under elevator, it is necessary to recur to, transfer.Best cooperation result is when elevator reaches turntable surface, is pulled out
Go out lock pin, pull out suspension ring, in the hanger for the another elevator being pushed into beside rotating disk, insert lock pin, carry another cylindrical drill tool.Long-term
Operation, drilling team employee has been set to get used to this operating type.But there are the following problems for this operating type：1st, elevator weight
Greatly, such as rated load 500t elevator weight 357kg, there is injury when moving to human body tendon, vertebra, or even can not move, it is necessary to
There is apparatus less important work；2nd, lock pin is pulled out, draws suspension ring, is pushed into another elevator, the process of mortise lock pin, it is easy to collide, damage people
Body, health is threatened；3rd, lock pin is pulled out repeatedly, drawing pushes away suspension ring, mortise lock pin, occurs suspension ring unavoidably and do not shift position onto, on
Slipped when carrying, form monaural ring accident（Suspension ring are not hung up properly, and unilateral stress, fracture drilling tool）；4th, transferred in travelling block to well
Mouth rotating disk, the moment that lock pin is extracted, slightly slow, effect of the suspension ring in 10t or so travelling block, the gravity of hook and inertia
Under, fly to jump out suspension ring hanger, easily form personal injury.
Part oil field uses manual three slips, is put into clamping drilling tool in rotating disk, lock pin is pulled out although eliminating, and drawing, which pushes away, hangs
Ring, the process of mortise lock pin, but it is the increase in the heavy physical labour of spudder；Master bushing is long-term use of, most of deformation to be present
Situation, easily block slips；Separately there is the air operated slips that part manufacturer production goes out the big square tile type of rotating disk, in use, proposing generous
Watt, air operated slips is put into, the labor intensity of operation, potential safety hazard existing for elimination can be mitigated in operation process, but work as well head
Deflection, drilling tool decentralization is too fast, or during brake failure, drilling tool coupling scrapes mutually with slips piece, causes serious accident；Often set card
Watt can only a kind of drilling tool of size of clamping, it is necessary to prepare the slips of various sizes, and to have standby.
The content of the invention
The invention provides a kind of drilling well chuck, overcomes the deficiency of above-mentioned prior art, it can effectively solve existing hang
Existing labor intensity is big in use, master bushing easily blocks slips, drilling tool coupling and slips and mutually scrapes, leads for card
Cause serious accident, infringement health, need prepare various sizes slips, waste time and energy, efficiency of construction is relatively low, safety be present
The problem of hidden danger.
The technical scheme is that realized by following measures：A kind of drilling well chuck, including base, terminal pad and
Valve, in a ring, base is provided with opening vertically to base, and the left side of valve can be rotatably mounted at the left side of opening, living
The right side of door can be rotatably mounted at the right side of opening；The inwall of base is in up big and down small taper, and the inwall of base is provided with
