According to the BOP gate plate body guiding structure disclosed by the invention, the problems that a cable cannot be reliably guided in a sealing groove when a BOP gate body is closed, and thus the cable is injured or pinched off are effectively solved, the structure is simple, the performance is reliable, the strength is high, and the cost is low.
Description
Technical field
The invention belongs to oil reservoir logging, perforating job equipment technical field, be specifically related to a kind of ram block body guide frame.
Background technology
During the wireline operations such as well logging, perforation, abnormal conditions occur, need to close preventer sealing well head.Existing ram block is only monolateral a guide frame, because cable can be crooked, without guiding one side cable, cannot lead, and when closing ram block body, cable can not import seal groove reliably, easily causes and crushes or the accident of pinch off cable.In addition the guide frame having and flashboard body adopt bolt or Type of Welding to connect firmly, and have hidden danger loosening or that drop in use, once difficulty and cost are salvaged very large in the loosening down-hole of dropping of guide pad.
Summary of the invention
The technical problem that the present invention solves: design a kind of ram block body guide frame, effectively solve cable while closing ram block body and can not reliably import seal groove, cause and crush or the problem of pinch off cable, simple in structure, dependable performance, intensity is high, and cost is low.
Technical scheme of the present invention: a kind of ram block body guide frame, comprise the identical two flashboard bodies of relative motion and structure, and there is radial groove on the inner face of flashboard body, the inner face projection of described flashboard body has two symmetrical spigot surfaces and two symmetrical guide strips, and two symmetrical spigot surfaces and two symmetrical guide strips lay respectively at radial groove both sides; Described two spigot surfaces and two guide strips are alternative arrangement on circumferentially, and is positioned at the spigot surface of radial groove the same side and the end face of guide strip forms respectively two " V " type guide frames; On the inner face of described flashboard body, there are two symmetrical arc notch that hold relative spigot surface, and two arc notch lay respectively at the outside of two guide strips, and the bottom surface that makes arc notch with hold into spigot surface coincide; On the inner face of described flashboard body, there are two symmetrical bar v notch vs that hold relative guide strip, and two bar v notch vs lay respectively at the inner side of two spigot surfaces, and the bottom surface that makes bar v notch v with hold into the end face of guide strip coincide; Described spigot surface, guide strip inner side all have arc groove, and the identical rear relative arc groove of two flashboard bodies forms cable channel.
Described spigot surface, guide strip and flashboard body are structure as a whole, and the external diameter of spigot surface, guide strip is consistent with flashboard body diameter.
The guide angle α of described " V " type guide frame is 100 °～145 °.
Between described spigot surface and arc notch, and the matched in clearance of be≤0.3mm between guide strip and bar v notch v.
The advantage that the present invention has and effect:
1, the present invention by arranging two " V " type guide frames and the breach that holds relative two " V " type guide frames on ram block body inner face, and make two " V " type guide frames cover preventer full-bore, realized the comprehensive guiding of cable when ram block body is closed, even also cable reliably can be imported to seal groove during cable bend, thoroughly solved and while closing preventer sealing well head, crushed or the problem of pinch off cable.
2, V of the present invention " type guide frame and flashboard body be structure as a whole, and whole Milling Process forms, and intensity is high.In addition after two flashboards cut out, " V " type guide frame coincide with the breach of relative holding of " V " type guide frame, form consistent with the external circle of flashboard and and the identical completely circular structure in flashboard chamber, make V " mutually support and location between type guide frame; further improved the intensity of " V " type guide frame and the operating pressure of bearing, met the reliability of working under superelevation operating pressure 105MPa and even 140MPa.

The specific embodiment
Below in conjunction with Fig. 1,2,3,4, a kind of embodiment of the present invention is described.
A ram block body guide frame, comprises the identical two flashboard bodies 1 of relative motion and structure, and on the inner face of flashboard body 1, has radial groove 2.The inner face projection of described flashboard body 1 has two symmetrical spigot surfaces 3 and two symmetrical guide strips 4, and two symmetrical spigot surfaces 3 and two symmetrical guide strips 4 lay respectively at radial groove 2 both sides; Described two spigot surfaces 3 and two guide strips 4 are alternative arrangement on circumferentially, and is positioned at the spigot surface 3 of radial groove 2 the same sides and the end face of guide strip 4 forms respectively two " V " type guide frames; On the inner face of described flashboard body 1, there are two symmetrical arc notch that hold relative spigot surface 36, and two arc notch 6 lay respectively at the outside of two guide strips 4, and the bottom surface that makes arc notch 6 with hold into spigot surface 3 coincide; On the inner face of described flashboard body 1, there are two symmetrical bar v notch vs 7 that hold relative guide strip 4, and two bar v notch vs 7 lay respectively at the inner side of two spigot surfaces 3, and the bottom surface that makes bar v notch v 7 with hold into the end face of guide strip 4 coincide; Described spigot surface 3, guide strip 4 inner sides all have arc groove 8, and the identical rear relative arc groove 8 of two flashboard bodies 1 forms cable channels 9.
Described spigot surface 3, guide strip 4 is structure as a whole with flashboard body 1, and the external diameter of spigot surface 3, guide strip 4 is consistent with flashboard body 1 external diameter.The guide angle α of described " V " type guide frame is 100 °～145 °.Between described spigot surface 3 and arc notch 6, and the matched in clearance of be≤0.3mm (30) between guide strip 4 and bar v notch v 7.
Wherein, radial groove 2, spigot surface 3, guide strip 4, arc notch 6, bar v notch v 7 and arc groove 8 are all that whole milling completes on the inner face of flashboard body 1, make " V " type guide frame cover preventer full-bore.The seamed edge of the seamed edge of described spigot surface 3, guide strip 4 end faces is all milled into fillet, scratches cable while avoiding leading.Guide angle α is definite according to the stroke of the frictional resistance between cable and spigot surface and flashboard body, and through verification experimental verification, α angle guide effect between 100 °～145 ° is best.
Guide frame of the present invention and gap structure adopt the matched in clearance of≤30, have both guaranteed the relative motion of two flashboard bodies, can, after two flashboards cut out, form and and flashboard chamber identical completely circular structure consistent with the external circle of flashboard again.Make V " mutually support and location between type guide frame, further improved the intensity of " V " type guide frame and the operating pressure of bearing, guarantee the intensity of guide frame and the reliability of work under superelevation operating pressure 105MPa and even 140MPa.
When the present invention uses, the seal 10 with cable seal groove 5 is embedded to radial groove 2, when closing flashboard body 1, make cable through two " V " type guide frame guiding, to slide into the cable seal groove 5 that cable channel 9 enters seal 10 end faces along the optional position of flashboard body 1 the inner, effectively solve the guiding problem of cable, simple in structure, dependable performance, intensity is high, and cost is low.
Above-described embodiment, is preferred embodiment of the present invention, is not used for limiting the scope of the present invention, thus all equivalent variations of being done with content described in the claims in the present invention, within all should being included in the claims in the present invention scope.
