Abstract
The utility model discloses a ball-shaped rubber core of a universal blowout preventer, which is a ball ring body consisting of a plurality of rigid supporting bodies 1 and a rubber body 2, wherein the rigid supporting bodies 1 is a whole body consisting of upper plate bodies 11, vertical plate bodies 12 and lower plate bodies13 which are connected into a whole; a plurality of supporting bodies 1 are distributed in the rubber body 2 in an equidistant and circular arrangement mode; the front part of the upper end of each vertical plate body 12 is provided with an inward concave arc-shaped concavity I14; and the upper surface of the outer end of each lower plate body 13 is provided with a downward concave arc-shaped concavity II15. The ball-shaped rubber core of the universal blowout preventer has the advantages that the two arc-shaped concavities are arranged on the vertical plate bodies and the lower plate bodies of the rigid supporting bodies, thus increasing the storage capacity of the rubber body, correspondingly increasing the rubber amount needed by the deformation amount of the rubber core, enhancing the resilience force of the rubber body, enlarging the contact surface and the adhesive force of the rigid supporting bodies and the rubber body and prolonging the service life of the rubber core.
Description
Technical field:
The utility model relates to the blowout hookup in a kind of oil gas well pressure control technology, specifically is the spherical glue core on the omnipotent preventer of a kind of oil gas well.
Background technology:
In the drilling process of oil or natural gas, if when running into high-pressure fluid in the stratum, the high-pressure fluid in the stratum will pour in the well, cause well kick or blowout phenomenon, therefore, in drilling process, just need utilize preventer to prevent the generation of " blowout " phenomenon.The glue core is a very important annex of being located on the preventer, and it is made up of a plurality of rigidity supporters and rubber bodies, during use, under the effect of the hydraulic control system of preventer, rubber bodies is inwardly stretched to stretch and is held drilling tool sealing drilling well tightly in the glue core, when not having drilling tool, and the closed allround well head.Existing glue core is owing to exist not enough on the physique structure of its supporter, make the relative less and rubber bodies reserves relative deficiency of bonding force of rubber bodies and the contact surface of supporter, cause its deflection less relatively, therefore, little in the sealing size, particularly under zero closed state, very easily cause rubber bodies to tear and damage the glue core, shortened the application life of glue core.Simultaneously, just known to the applicant, owing to reasons such as glue core structure designs and production technologies, at present, the glue core of domestic production maximum is the glue core of 18 supporter combinations, not satisfy the needs of economic development and drilling technology development far away.
The utility model content:
The technical problems to be solved in the utility model is, at the deficiency of above-mentioned prior art situation and existence, provides a kind of deflection relatively large, is difficult for causing rubber bodies to tear damage, the spherical glue core of the omnipotent preventer of long service life.
Technical solution of the present utility model is: the spherical glue core of a kind of omnipotent preventer, form the ball body by a plurality of rigidity supporters and rubber bodies, the rigidity supporter is the inner small and outside big wedge that is fused by upper plate body, riser body, lower body, a plurality of rigidity supporters are that equidistant circular arrangement is distributed in the rubber bodies, be characterized in, it is recessed to be provided with an indent arc in the upper-end front of riser body, is provided with on the outer end of lower body that arcs of recesses is recessed.
The utility model also has following feature and advantage:
As improving and improving, described rigidity supporter is set to 18-22.Supporter in the spherical glue core of the omnipotent preventer of present domestic maximum be set to 18, the utility model is provided with 18-22, to satisfy the needs of drilling technology development.
As further improving and improving, described rigidity supporter is set to 22.To satisfy the needs of drilling technology development.
After adopting above structure, compared with prior art, the utlity model has following advantage: because it is recessed to be provided with two arcs on the riser body of rigidity supporter, lower body, thereby increased the storage capacity of rubber bodies, correspondingly increased the required rubber mass of deflection of glue core, promote the screen resilience of rubber bodies, strengthened the contact surface and the bonding force of rigidity supporter and rubber bodies, prolonged the application life of glue core.
Description of drawings:
Fig. 1 is the spherical glue core of the omnipotent preventer of a utility model schematic top plan view;
Fig. 2 is the spherical glue cored structure of the omnipotent preventer of a utility model schematic diagram;
Fig. 3 is the supporting body structure schematic diagram in the spherical glue core of the omnipotent preventer of the utility model.
Shown in the figure: 1, rigidity supporter, 11, upper plate body, 12, the riser body, 13, lower body, 14, the recessed I of arc, 15, the recessed II of arc, 2, rubber bodies.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Shown in the accompanying drawing, the spherical glue core of a kind of omnipotent preventer, form the ball body by a plurality of rigidity supporters 1 and rubber bodies 2, rigidity supporter 1 is the integral body that is fused by upper plate body 11, riser body 12, lower body 13, a plurality of rigidity supporter 1 is distributed in the rubber bodies 2 for equidistant circular arrangement, upper-end front at riser body 12 is provided with the recessed I 14 of an indent arc, is provided with the recessed II 15 of arcs of recesses on the outer end of lower body 13.
Embodiment one
Above-mentioned rigidity supporter is placed in the mould around the equidistant circular arrangement in the same center of circle, present embodiment is set to 18 supporters, the rubber that to plasticate then injects in the mould and passes through sulfuration process, make riser body 12, lower body 13 sticking being embedded in the rubber bodies 2 of supporter 1, and upper plate body 11 shows on rubber bodies 2 tops especially.
Embodiment two
Its implementation process is with embodiment one, and different is that rigidity supporter 1 is set to 22.
Above embodiment is made into the spherical glue core of omnipotent preventer and belongs to the spherical glue core of high pressure, meets 18-70 (7 1/16 * 10000psi) and 28-70 (11 * 10000psi) and 35-70 (13 5/8 * 10000psi) specification requirements.
