Abstract
The utility model discloses an easy-mounting and easy-dismounting rotary blowout preventer, which comprises an actuator assembly, a rotary assembly, a liquid-driven clamp assembly and a controlling head base assembly. The rotary assembly comprises a rubber seal barrel, a rubber seal suspending joint, an upper rubber seal and a bearing assembly. The controlling head base assembly comprises a base casing and a flange joint and is characterized in that matched flange structures are arranged on the rubber seal barrel and the rubber seal suspending joint, and the rubber seal barrel and the rubber seal suspending joint are connected through a plurality of bolts. To further improve the easy-mounting and easy-dismounting rotary blowout preventer, the inner wall of the rubber seal barrel which is close to a flange plate is provided with an inner conical surface, the outer wall of the rubber seal suspending joint which is close to the flange plate is provided with an matched outer conical surface. The easy-mounting and easy-dismounting rotary blowout preventer has the advantages that the rubber seal and the flange joint are convenient and fast to replace, and the service life of the equipment can be prolonged.
Description
Technical field
The utility model relates to a kind of rotating blowout preventer that is used for drilling well.
Background technology
Under-balanced drilling technology is state-of-the-art in the world at present drilling technology, rotating blowout preventer is a key equipment of realizing under balance pressure drilling, present already used rotating blowout preventer, comprise the driver assembly, the rotation assembly, the clip assembly surges, control head base assembly, the rotation assembly comprises glue core tube, glue core suspension joint, with glue core suspension joint by bolted gluing core, bearing assembly etc., control head base assembly comprises base and flange socket, wherein glue core tube and glue core suspension joint are by being threaded, flange socket is the single head flange, and one end and base welding connect firmly; Need to make regular check on and change the glue core in the under-balance drilling operation, existing glue core tube is connected for the full thread formula with glue core suspension joint, and the screw thread travel of glue core suspension joint is very long during dismounting, checks and change the big and length consuming time of glue core labour intensity; When down-hole pressure is too high, the pipeline that flange socket connect is as the pressure release circulation canal, the upper inside walls that a large amount of impurity during pressure release in the high-pressure fluid can make flange socket is than quick-wearing, but flange socket can not change again, often causes scrapping of a The whole control base assembly.
The utility model content
The purpose of this utility model is at the prior art above shortcomings, and a kind of easy mounting or dismounting rotating blowout preventer is provided, and it has the glue core and flange socket is changed advantage easily and efficiently, and can prolong the application life of equipment.
For achieving the above object, easy mounting or dismounting rotating blowout preventer of the present utility model, comprise the driver assembly, rotate assembly, the clip assembly that surges, control head base assembly, the rotation assembly comprises glue core tube, glue core suspension joint and gluing core, bearing assembly, control head base assembly comprises base housing and flange socket, it is characterized in that glue core tube and glue core suspension joint are provided with the flange arrangement that matches, the two is by several Bolt Connection.
The utility model is when checking and change the glue core, only need on the dismounting glue core suspension joint bolt, on carry glue core suspension joint and get final product, the guide-localization stroke of glue core suspension joint is short and need not to rotate, check and the little and weak point consuming time of replacing glue core labour intensity, have and change advantage easily and efficiently.
As further improvement of the utility model, be provided with internal conical surface at the inwall of glue core tube adjacent flange dish, be provided with the outer conical surface that matches at the outer wall of glue core suspension joint adjacent flange dish; By the taper seat that glue core tube and glue core suspension joint match, labour intensity is further raised the efficiency, is reduced in the accurate contraposition in the time of can realizing assembling.
As further improvement of the utility model, described flange socket is the double end flange, and its end and base housing link by flange arrangement; After the upper inside walls wearing and tearing of flange socket, make flange socket rotate to an angle by flange arrangement, allow the less inwall of other wearing and tearing of flange socket be in upper side position, both be convenient to dismounting, can increase the service life again.
As further improvement of the utility model, the inwall of described flange socket is provided with hard alloy layer; Can improve abrasion resistance, further increase the service life.
In sum, the utlity model has glue core and flange socket and change advantage easily and efficiently, and can prolong the application life of equipment.
Description of drawings
Fig. 1 is the front view of utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, should easily install and remove rotating blowout preventer, comprise driver assembly 1, rotation assembly 2, the clip assembly 3 that surges, control head base assembly 4, rotation assembly 2 comprises glue core tube 5, glue core suspension joint 6, gluing core 7, bearing assembly (not shown), glue core tube 5 and glue core suspension joint 6 are provided with the flange arrangement that matches, the two connects by several bolts 8, inwall at glue core tube 5 adjacent flange dishes is provided with internal conical surface 5a, is provided with the outer conical surface 6a that matches at the outer wall of glue core suspension joint 6 adjacent flange dishes; Control head base assembly 4 comprises base housing 9 and double end flange 10, and an end of double end flange 10 and base housing 9 link by flange arrangement, and the inwall of double end flange 10 is provided with hard alloy layer 10a by welding.
The utility model is when checking and change glue core 7, only need the bolt 8 on the dismounting glue core suspension joint, on carry glue core suspension joint and get final product, the stroke of glue core suspension joint 6 is short and need not to rotate, check and change the little and weak point consuming time of glue core labour intensity, by taper seat 5a and the 6a that glue core tube 5 and glue core suspension joint 6 match, the accurate contraposition in the time of can realizing assembling has and changes advantage easily and efficiently; A large amount of impurity during pressure release in the underground high-pressure fluid mainly wash away the upper inside walls of double end flange 10, after the upper inside walls wearing and tearing of double end flange 10, make double end flange 10 rotate to an angle by flange arrangement, allow the less inwall of double end flange 10 other wearing and tearing be in upper side position, both be convenient to dismounting, can increase the service life again, hard alloy layer 10a can improve abrasion resistance, further increases the service life.
