Description
Technical field
The present invention relates to a kind of technical equipment that is used for resources explorations such as coal, coal bed gas, natural gases, put the full-hydraulic multifunctional wellhead device of the full-hydraulic multifunctional coal bed gas rig of constructing especially for coal bed gas prospecting, exploitation, Device in Gas pump drainage with the coal emergency dealing.
Background technology
In worldwide, along with the continuous enhancing of the exhausted day by day and people's of petroleum resources environmental consciousness, the exploration and development of the clean type energy-coal bed gas with utilize one of natural energy resource that has become people's great attention.The tempting potentiality of coal bed gas are at first from its huge reserves.In the U.S., 2000m is equivalent to the half the many of conventional gas reserves with shallow coal bed gas reserves.In China, the coal bed gas reserves occupy the third place in the world, and land 2000m is 31,000,000,000,000 m with shallow coal bed gas resource
3, so big reserves and energy resource supply more and more have the current society of crisis, and the fair exploration of coal bed gas must be very wide.
The pump drainage of gas is put before going into operation in the colliery; Can be used as on the one hand clear energy sources in addition economic utilization promote the well-being of mankind; Be very favourable to Safety of Coal Mine Production, protection environment, minimizing disaster and increase economic benefit on the other hand, for this reason, research and development multifunctional all-hydraulic coal bed gas rig; It is supporting to improve the cbm exploration technical equipment, optimizes the task of top priority that drilling operation technology becomes cbm exploration and extraction work.
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, and traditional spindle-type drill is used 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, and offshore boring island is arranged; Can arrange wellhead assembly and preventer, but because of it is the rotating disk driving, 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, and because of the relative oil-well rig of equipment manufacturing cost is 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 problem that the present invention will solve is the deficiency to 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 problem that the present invention will solve realizes that through following technical scheme a kind of full-hydraulic multifunctional wellhead device comprises the well head workbench; Be characterized in: about on the well head workbench, being provided with to the slideway that is provided with; Movable deck is housed on slideway, 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 be housed
Said 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,
Said 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,
Said 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 problem that the present invention will solve can also further realize through following technical scheme; 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 through position-limitting pin, spring housing is contained on the position-limitting pin below the cushion collar, and cushion collar is provided with the boss that upwards withstands on tapering centering pilot seat bottom.
The technical problem that the present invention will solve can also further realize through following technical scheme, is provided with between movable deck and the well head workbench to plug and unplug lock and tightly install.
The present invention 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 property of insert-pull pin locking having increased well head mobile device; Centering of guide holder tapering and flange location, snap ring, tighten and self-locking along guide holder flange guiding deadweight slippage with the round centering of tapering automatically, can change the snap ring of different size quickly and easily, and quick centering tightens drilling rod or sleeve pipe safely and reliably; When guaranteeing under the situation of reliable chucking, to change snap ring, 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.
