Coal bed gas rig full-hydraulic multifunctional wellhead device is exactly to be one of supporting critical component of multifunctional all-hydraulic coal bed gas rig.
The drilling equipment that is used for the cbm exploration exploitation at present mainly is an oil-well rig, the traditional spindle-type drill in water source rig and coalfield.Practice shows, more than three types of rigs all can not be applicable to well and the job requirements of creeping into of cbm development well obviously have following problem:
1, oil-well rig is used for the cbm exploration construction, can satisfy the probing demand on the function, offshore boring island is arranged, can arrange wellhead assembly and preventer, but be that rotating disk drives because of it, no pressurization function, drilling efficiency is low, and rig and supporting cost are too expensive, and construction cost is too high, other is because of huge, the smooth well site of equipment and the cost height of repairing the roads, relocation equipment cycle are grown, difficulty is many, and migration cost is high-leveled and difficult with extensive use.
2, the water source rig is used for the cbm exploration construction, because of the relative oil-well rig of equipment manufacturing cost low, construction cost is lower, because of there not being offshore boring island, be not easy to arrange wellhead assembly and preventer, in the construction blowout and gas leakage might take place, have serious potential safety hazard, and be that rotating disk drives equally, existence can not be pressurizeed and the inefficiency problem.
3, traditional spindle-type core drill, the equipment input cost is lower, has the vertical shaft pressurization function, and drilling efficiency is slightly high, and existing problems are not have offshore boring island equally, are not easy to arrange wellhead assembly and preventer, and drill capacity is less, and it is more shallow to hole.
4, all incompatibility heavy caliber drilling wells of above all kinds equipment can not be descended magnifying diameter sleeve pipe and drilling tool.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed the different drilling technologies of a kind of adaptation, can transfer the full-hydraulic multifunctional wellhead device of different size sleeve pipe.
The technical problems to be solved in the utility model is achieved through the following technical solutions; A kind of full-hydraulic multifunctional wellhead device; Comprise the well head workbench; Be characterized in: about on the well head workbench, being provided with to the slideway that arranges; At slideway movable deck is housed; About movable deck is set to two; Semicircle bayonet socket about being provided with of two movable deck joint symmetries; In bayonet socket, be provided with the taper hole seat; In the taper hole seat, be provided with tapering centering pilot seat; In tapering centering pilot seat, the snap ring assembly is housed
Described taper hole seat is provided with the centering endoporus of taper, the taper hole seat and movable deck is corresponding be set to about two,
Described tapering centering pilot seat evenly is provided with four centering teeth, and the centering tooth is provided with the conical surface that cooperates centering with the centering endoporus of above-mentioned taper hole seat, tapering centering pilot seat about the center line of two wherein relative teeth of feeling relieved is divided into two,
Described snap ring assembly is formed by four, and every outer wall all is provided with positioning boss, and positioning boss is arranged between every two the adjacent centering teeth of tapering centering pilot seat.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, be provided with spring bumper in taper hole seat bottom, spring bumper comprises position-limitting pin, spring and cushion collar, the bottom that is contained in the taper hole seat that cushion collar floats by position-limitting pin, spring housing is contained on the pin below the cushion collar, and cushion collar is provided with the boss that upwards withstands on tapering centering pilot seat bottom.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, is provided with between movable deck and the well head workbench to plug and unplug lock and tightly install.
The utility model compared with prior art on the basis of original well head workbench, has increased the well head translating device; Plugging and unplugging lock tightly installs; Tapering centering pilot seat guiding and centering device; Change various snap rings and buffering structure fast.The well head translation strengthens opening diameter, adapts to different drilling technologies, transfers the sleeve pipe of different size; The rigidity and the stable working of insert-pull pin locking having increased well head mobile device; Centering of guide holder tapering and flange location, snap ring, tightens and self-locking along guide holder flange guiding deadweight slippage automatically with the round centering of tapering, can change the snap ring of different size quickly and easily, and centering tightens drilling rod or sleeve pipe safely and reliably fast; When guaranteeing to change snap ring under the situation of reliable chucking, dismantles by buffer brisk convenience.
The present invention can satisfy multifunctional all-hydraulic coal bed gas rig multiplex (MUX) process probing requirement, transfers the diameter dimension demand of all size sleeve pipe, and perfect in shape and function, easy to operate, quick, safe and reliable, compact conformation.
