Description
Technical field
The invention belongs to oil reservoir logging, perforating job equipment technical field, be specifically related to a kind of anti-Spray apparatus flashboard body guide frame.
Background technology
When the wireline operations such as well logging, perforation, abnormal conditions occur, need to close preventer sealingWell head. Existing ram block is only monolateral a guide frame, because cable can be bending, in nothingThe side cable that leads cannot lead, and in the time closing ram block body, cable can not be led reliablyEnter seal groove, easily cause and crush or the accident of pinch off cable. In addition the guide frame having and lockPlate body adopts bolt or Type of Welding to connect firmly, and has hidden danger loosening or that drop in use, onceThe loosening down-hole of dropping of guide pad, salvages difficulty and cost very large.
Summary of the invention
The technical problem that the present invention solves: design a kind of ram block body guide frame, effectivelyWhen ram block body is closed in solution, cable can not reliably import seal groove, causes and crushes or pinch offThe problem of 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, comprises relative motionAnd the identical two flashboard bodies of structure, and on the inner face of flashboard body, there is radial groove, instituteThe inner face projection of stating flashboard body has two symmetrical spigot surfaces and two symmetrical guide plates,And two symmetrical spigot surfaces and two symmetrical guide plates lay respectively at radial groove both sides; InstituteState two spigot surfaces and two guide plates alternative arrangement on circumferentially, and it is same to be positioned at radial grooveThe spigot surface of side and the end face of guide plate form respectively two " V " type guide frames; Described lockOn the inner face of plate body, there are two symmetrical arc notch that hold relative spigot surface, and twoArc notch lays respectively at the outside of two guide plates, and the bottom surface that makes arc notch with hold intoSpigot surface coincide; On the inner face of described flashboard body, there are two and symmetrical hold relative guidingThe bar v notch v of plate, and two bar v notch vs lay respectively at the inner side of two spigot surfaces, and make barThe bottom surface of v notch v with hold into guide plate end face coincide; In described spigot surface, guide plateSide all has arc groove, and the identical rear relative arc groove composition cable trough of two flashboard bodies.
Described spigot surface, guide plate and flashboard body are structure as a whole, and spigot surface, guide plateExternal diameter 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 be between guide plate and bar v notch v≤The matched in clearance of 0.3mm.
The advantage that the present invention has and effect:
1, the present invention by arranging two " V " type guiding knots on ram block body inner faceStructure and the breach that holds relative two " V " type guide frames, and make two " V " type guiding knotsStructure covers preventer full-bore, has realized the comprehensive of cable in the time that ram block body is closed and has ledTo, even also cable reliably can be imported to seal groove when cable bend, thoroughly solved close anti-When spray apparatus sealing well head, crush or the problem of pinch off cable.
2, V of the present invention " type guide frame and flashboard body be structure as a whole, overall Milling ProcessForm, intensity is high. In addition after two flashboards cut out, " V " type guide frame and relative holding " V "The breach of type guide frame coincide, form consistent with the external circle of flashboard and with identical whole in flashboard chamberCircle structure, makes V " mutually support and location between type guide frame, further improve " V "The intensity of type guide frame and the operating pressure of bearing, met at superelevation operating pressure 105MPaAnd even the reliability of working under 140MPa.

Detailed description of the invention
Below in conjunction with Fig. 1,2,3,4, a kind of embodiment of the present invention is described.
A kind of ram block body guide frame, comprises relative motion and structure identical twoFlashboard body 1, and on the inner face of flashboard body 1, there is radial groove 2. Described flashboard body 1Inner face projection has two symmetrical spigot surfaces 3 and two symmetrical guide plates 4, and twoSymmetrical spigot surface 3 and two symmetrical guide plates 4 lay respectively at radial groove 2 both sides; InstituteState two spigot surfaces 3 and two guide plates 4 alternative arrangement on circumferentially, and be positioned at radial grooveThe spigot surface 3 of 2 the same sides and the end face of guide plate 4 form respectively two " V " type guiding knotsStructure; On the inner face of described flashboard body 1, there are two symmetrical arcs that hold relative spigot surface 3V notch v 6, and two arc notch 6 lay respectively at the outside of two guide plates 4, and make arcThe bottom surface of v notch v 6 with hold into spigot surface 3 coincide; On the inner face of described flashboard body 1There are two symmetrical bar v notch vs 7 that hold relative guide plate 4, and two bar v notch vs 7Lay respectively at the inner side of two spigot surfaces 3, and the bottom surface that makes bar v notch v 7 with hold into leadEnd face to plate 4 coincide; Described spigot surface 3, guide plate 4 inner sides all have arc groove 8,And after two flashboard bodies 1 coincide, relative arc groove 8 forms cable trough 9.
Described spigot surface 3, guide plate 4 are structure as a whole with flashboard body 1, and spigot surface 3,The external diameter of guide plate 4 is consistent with flashboard body 1 external diameter. The guiding of described " V " type guide frameAngle α is 100 °～145 °. Between described spigot surface 3 and arc notch 6, and guidingThe matched in clearance of be≤0.3mm between plate 4 and bar v notch v 7 (30).
Wherein, radial groove 2, spigot surface 3, guide plate 4, arc notch 6, bar v notch v7 and arc groove 8 be all that overall milling completes on the inner face of flashboard body 1, make " V "Type guide frame covers preventer full-bore. The seamed edge of described spigot surface 3, guide plate 4 end facesSeamed edge be all milled into fillet, while avoiding leading, scratch cable. Guide angle α according to cable with leadStroke to the frictional resistance between face and flashboard body is definite, and through verification experimental verification, α angle existsGuide effect the best between 100 °～145 °.
Guide frame of the present invention and gap structure adopt the matched in clearance of≤30, have both ensured twoThe relative motion of flashboard body, again can be after two flashboards cut out, form consistent with the external circle of flashboard andWith the identical completely circular structure in flashboard chamber. Make V " mutually support and location between type guide frame,Further improve the intensity of " V " type guide frame and the operating pressure of bearing, ensured superUnder high workload pressure 105MPa and even 140MPa, the intensity of guide frame and work is reliableProperty.
When the present invention uses, the seal 10 with cable seal groove 5 is embedded to radial groove2, in the time closing flashboard body 1, make the cable can be along the optional position warp of flashboard body 1 the innerTwo " V " type guide frame guiding slides into cable trough 9, and to enter the cable of seal 10 end faces closeSealing groove 5, effectively solves the guiding problem of cable, simple in structure, dependable performance, and intensity is high,Cost is low.
Above-described embodiment, is preferred embodiment of the present invention, is not used for limiting the present invention realExecute scope, therefore all equivalent variations of being done with content described in the claims in the present invention all should compriseWithin the claims in the present invention scope.
