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, in order to more bit change, well logging or setting of casing drifting, need the drilling tool of thousands of meters in well to propose, more G.I.H again after bit change, well logging.In operation process, driller stands in boring winch side, a hand steered brake handle, pushes away clutch switch on the other hand, controls travelling block put-on and delegated drilling tool, and two spudders keep button, shackle on well head side is carried out, remove elevator operation.During lower brill, driller mentions brake handle, the elevator hanging drilling tool below travelling block is transferred to well head together with drilling tool, be seated at rotating disk, the lock pin of elevator both sides is extracted by two spudders, pull-out suspension ring, push in the hanger of another elevator on rotating disk side, insert lock pin, driller carries travelling block to quadruple board platform, frame work pulls open elevator valve, be buckled on another cylindrical drill tool, mention, with well head drilling tool make-up, after upper button, mention drilling tool, open the elevator valve on turntable surface, move rotating disk side to, transfer drilling tool to well head, be seated at rotating disk, so move in circles, put another cylindrical drill tool.In this link, the hanger opening of elevator is less than 100mm, and driller can not just to stop tight braking at turntable surface, if early stopped, not in place, needs to continue to transfer; If evening stops, suspension ring can withstand ear under elevator, must recur to, transfer.Best cooperation result is when elevator arrives turntable surface, extracts lock pin, and pull-out suspension ring, push in the hanger of another elevator on rotating disk side, insert lock pin, carry another cylindrical drill tool.Long-term operation, has made drilling team employee get used to this operating type.But there are the following problems for this operating type: 1, elevator weight is large, the heavy 357kg of the elevator as rated load 500t, has injury to human body tendon, vertebra when moving, even cannot move, must have apparatus less important work; 2, pull out lock pin, draw suspension ring, push another elevator, the process of mortise lock pin, be easy to collision, damage human body, health is threatened; 3, repeatedly pull out lock pin, draw and push away suspension ring, mortise lock pin, occur that suspension ring do not shift position onto unavoidably, slippage when above proposing, form monaural ring accident (suspension ring do not hang up properly, monolateral stressed, and fracture drilling tool); 4, transfer to well head rotating disk at travelling block, the moment that lock pin is extracted, slightly slow, suspension ring, under the effect of the travelling block of about 10t, the gravity of hook and inertia, fly to jump out suspension ring hanger, easily form personal injury.
part oil field uses manual three slips, puts into rotating disk and holds drilling tool, pull out lock pin although eliminate, draw and push away suspension ring, the process of mortise lock pin, be the increase in the heavy physical labour of spudder; Master bushing Long-Time Service, there is the situation of distortion in major part, easily blocks slips; Part manufacturer production is separately had to go out the air operated slips of the large square tile type of rotating disk, during use, propose large quadrel, put into air operated slips, the labour intensity of operation in operation process, can be alleviated, eliminate the potential safety hazard existed, but when well head deflection, drilling tool is transferred too fast, or during brake failure, drilling tool coupling and slips sheet are swiped mutually, cause serious accident; Often overlap the drilling tool that slips can only hold a kind of size, need the slips preparing various sizes, and will standby be had.
Summary of the invention
the invention provides a kind of drilling well chuck, overcome the deficiency of above-mentioned prior art, it can effectively solve, and the labour intensity that existing elevator in use exists is large, master bushing easily blocks that slips, drilling tool coupling and slips are mutually swiped, cause serious accident, damage health, need to prepare the slips of various sizes, wasted time and energy, efficiency of construction is lower, there is the problem of potential safety hazard.
