Abstract
The utility model discloses novel double flashboard thick oil blowout preventer, which comprises a shell body, a half-sealed flashboard assembly and a complete-sealed flashboard assembly. The half-sealed flashboard assembly and the complete-sealed flashboard assembly are arranged in the main channel of the shell body provided with an upper-lower distribution, The complete-sealed flashboard assembly comprises a complete-sealed flashboard, a sealed ring and a long screw rod, wherein, the interface of the complete-sealed flashboard and the sealed ring is provided with a horniness alloy layer of 0.5 mm to 1.0 mm. the axes of the half-sealed flashboard assembly and the complete-sealed flashboard assembly are vertical with each other. The interface of the complete-sealed flashboard and the sealed ring is provided with a horniness alloy layer, so the high temperature resistance performance and the service life of the complete-sealed flashboard assembly are improved, the maintenance and replacing time is saved, and the utility model is in particular suitable for the blowout preventing operation of a thick oil well. Besides, the axes of the half-sealed flashboard assembly and the complete-sealed flashboard assembly are in vertical arrangement, so the integral height of the blowout preventer is effectively reduced, the operation is convenient, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of oilfield control appliance, particularly a kind of novel double-gate plate viscous crude preventer that is applicable to that heavy oil wells is used.
Background technology
In oilfield drilling and maintenance process, well kick and gas blowout accident happen occasionally, and must use preventer to seal well head, to guarantee the safety of operating personnel and equipment.The present double ram type preventer that uses, it mainly is made up of housing, half-closed type flashboard assembly and full-enclosed type flashboard assembly, half-closed type flashboard assembly and full-enclosed type flashboard assembly is installed respectively in the main channel of housing is from top to bottom constituted double ram type preventer.When in the well head oil pipe being arranged, adopt half-closed type flashboard assembly, hold oil pipe tightly, form sealing; When in the well head during no oil pipe, then adopt full-enclosed type flashboard assembly that well head is sealed.Heavy oil wells is in recovery process, because the viscosity of thickened oil height is mobile poor, need heat viscosity reduction to it by steam in jection in well usually, has so just improved well temperature; And the full-enclosed type flashboard assembly of existing double ram type preventer, rubber seal resistance to elevated temperatures set between its flashboard and the joint ring is poor, can't seal high-temperature gas in the well, reduced the blowout prevention effect, and lack easy to wear, application life, needs often to change, and influences normal production operation.In addition, the axis of the half-closed type flashboard assembly of existing double ram type preventer and full-enclosed type flashboard assembly goes to upper and lower and be arranged in parallel, in order to leave enough operating spaces, the spacing of two flashboard assemblies is bigger, the overall height of preventer and the operation height of raised platform around a well have been strengthened, bring great inconvenience to operating personnel, increased working strength, reduced operating efficiency.
The utility model content
For overcoming the deficiencies in the prior art part, the utility model provide a kind of rational in infrastructure, easily manufactured, effectively improve the novel double-gate plate viscous crude preventer in resistance to elevated temperatures and application life, also reduce its whole height, be convenient to operation, increase work efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises housing, half-closed type flashboard assembly and full-enclosed type flashboard assembly; Half-closed type flashboard assembly and full-enclosed type flashboard assembly go to upper and lower to distribute and are installed in the housing main channel, it is characterized in that: comprise the full-enclosed type flashboard assembly of blind rams, joint ring and long lead screw, be equipped with the hard alloy layer of 0.5～1.0mm on its blind rams and the joint ring contact surface.
For reducing the whole height of preventer, be convenient to operation, to increase work efficiency, the axis of above-mentioned half-closed type flashboard assembly and full-enclosed type flashboard assembly is perpendicular.
The beneficial effects of the utility model are: owing to be equipped with hard alloy layer on blind rams and joint ring contact surface, thereby the resistance to elevated temperatures and the application life of full-enclosed type flashboard assembly have been improved, save maintenance and replacing time, be specially adapted to the preventing spraying operation of heavy oil wells; And the axis of half-closed type flashboard assembly and full-enclosed type flashboard assembly is vertical setting, has reduced the whole height of preventer effectively, be convenient to operation, improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the right view of Fig. 1.
Among the figure: 1 is that housing, 2 is that main channel, 3 is that half-closed type flashboard assembly, 3-1 are that preceding sealing, 3-2 are that half-closed type flashboard, 3-3 are that full-enclosed type flashboard assembly, 4-1 are that blind rams, 4-2 are that hard alloy layer, 4-3 are that joint ring, 4-4 are long lead screw for short leading screw, 4.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model comprises: housing 1, half-closed type flashboard assembly 3 and full-enclosed type flashboard assembly 4, the middle part of housing 1 is provided with main channel 2, half-closed type flashboard assembly 3 and full-enclosed type flashboard assembly 4 go to upper and lower to distribute and are installed in the main channel 2 of housing 1, and half-closed type flashboard assembly 3 is perpendicular with the axis of full-enclosed type flashboard assembly 4, constitutes tee T.The full-enclosed type flashboard assembly 4 that comprises blind rams 4-1, joint ring 4-3 and long lead screw 4-4, its joint ring 4-3 is installed on 2 inwalls of main channel, blind rams 4-1 is placed in the flashboard chamber of housing 1 one sides, the end of long lead screw 4-4 passes housing 1 and links to each other with blind rams 4-1, adopt spray welding process to be provided with the Ni60TH2 hard alloy layer 4-2 of 0.5～1.0mm on blind rams 4-1 and the joint ring 4-3 contact surface, to improve its sealing, heat-resisting and abrasion resistance, prolong its application life.
During use, at first the utility model is installed on the well head of oil well.When needs partly seal, rotate the short screw mandrel 3-3 in both sides simultaneously, promote partly to seal flashboard 3-2 and move to main 2 centers all, partly seal flashboard 3-2 until both sides and contact, make the preceding sealing 3-1 crimp on the half envelope flashboard 3-2 realize half envelope thereby apply a point load again.When needs seal entirely, rotate long lead screw 4-4 and drive the opposite side motion of blind rams 4-1 to main channel 2, until contact housing 1 inwall, this moment, blind rams 4-1 and joint ring 4-3 realized sealing.Because blind rams 4-1, joint ring 4-3 go up equal surfacing Ni60TH2 hard alloy layer 4-2 is arranged, thereby improved heat-resisting and abrasion resistance, prolonged application life.
