Abstract
The invention relates to the technical field of vertical drilling guard plate tools and discloses a special type guard plate. The special type guard plate comprises a left guard plate body and a right guard plate body, the right end of the left guard plate body and the left end of the right guard plate body are hinged together, and installation holes are formed in the left portion of the left guard plate body and the right portion of the right guard plate body. The special type guard plate is reasonable and compact in structure and convenient to use; the left guard plate body is hinged with the right guard plate body, so that the guard plate can be changed within a multi-angle range; and a right pin hole is designed into a long round hole or in a long round hole shape for being matched with an end cover hole, so that the angular change range of the guard plate can be expanded, and the drilling requirement for the high well expansion rate is met.
Description
Technical field
The present invention relates to vertical drilling backplate technical field of tools, is a kind of extraordinary backplate.
Background technology
Vertical drilling system is mechanical, electrical, the liquid integrated downhole closed loop drilling tool of collection, is that the revolutionary character of conventional anti-oblique technology breaks through, and is a cutting edge technology in our times drilling well field.This instrument can easily tiltedly layer realize initiatively anti-oblique, greatly liberate the pressure of the drill, improve rate of penetration, the vertical drilling system instrument of domestic independent research has been broken external monopolization to this technology, allow domestic drilling well field in this technical international most advanced level that is in, backplate is the indispensable parts of vertical drilling system instrument, and the working effect of existing backplate in vertical drilling system tool work process is not very good, the drill tools well straightening pushes away the borehole wall by backplate owing to hanging down, Different Strata alters a great deal with the borehole size that same drill bit gets out, the angle that common backplate opens is limited, can not satisfy the larger drilling well needs of well amplification degree.
Summary of the invention
The invention provides a kind of extraordinary backplate, overcome the deficiency of above-mentioned prior art, it can effectively solve the problem that existing common backplate can not satisfy the larger drilling well needs of well amplification degree.
Technical scheme of the present invention realizes by following measures: a kind of extraordinary backplate, comprise left backplate and right backplate, and the right-hand member of left backplate and the left end of right backplate are hinged, and the left part of left backplate and the right part of right backplate are distributed with installing hole.
The below is the further optimization and/or improvements to the foregoing invention technical scheme:
The right-hand member of above-mentioned left backplate can have right pin-and-hole, and the left end of right backplate has left pin-and-hole, is set with bearing pin in the left pin-and-hole, and the front portion of bearing pin is sleeved in the right pin-and-hole.
The front side left part of above-mentioned right backplate can be fluted, and left pin-and-hole is positioned at concave station, and the right part of left backplate is sleeved in the concave station.
Above-mentioned right pin-and-hole can be slotted hole.
Above-mentioned right pin-and-hole can be opening U-shaped hole to the right, and the right-hand member of left backplate is installed with end cap, and the end cap left end has the opening corresponding with the right pin-and-hole ending cover hole that takes the shape of the letter U left.
Can be installed with adjusting pad between the right-hand member of above-mentioned left backplate and the end cap left end, on the adjusting pad of corresponding right pin-and-hole position through hole be arranged.
Above-mentioned left backplate, adjusting pad and end cap can be bolted and be fixed together.
Reasonable and compact in structure of the present invention, easy to use, it is hinged by left backplate and right backplate, thereby realize the variation of multi-angle scope, by right pin-and-hole being made as slotted hole or cooperating ending cover hole to be oval hole shape, all can increase its angle excursion, thereby satisfy the larger drilling well needs of well amplification degree.
Description of drawings
Accompanying drawing 1 is looked the sectional structure schematic diagram for the master of most preferred embodiment of the present invention.
Accompanying drawing 2 is that accompanying drawing 1 is at the local structure for amplifying schematic diagram at A place.
Coding in the accompanying drawing is respectively: 1 is left backplate, and 2 is right backplate, and 3 is installing hole, and 4 is right pin-and-hole, and 5 is bearing pin, and 6 is end cap, and 7 is ending cover hole, and 8 is adjusting pad, and 9 is through hole, and 10 is concave station, and 11 is bolt.
The specific embodiment
The present invention is not subjected to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual conditions.
In the present invention, for convenience of description, the description of the relative position relation of each parts all is that the Butut mode according to Figure of description 1 is described, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description.
The invention will be further described below in conjunction with embodiment and accompanying drawing:
Shown in accompanying drawing 1,2, this special type backplate comprises left backplate 1 and right backplate 2, and the left end of the right-hand member of left backplate 1 and right backplate 2 is hinged, and the right part of the left part of left backplate 1 and right backplate 2 is distributed with installing hole 3.In use, can left backplate 1 and right backplate 2 all be fixed on the body that bores that hangs down by installing hole 3, left backplate 1 and right backplate 2 are hinged, can make to form different angles between it, thereby adapt to the drilling well needs of Different Strata.
Can according to actual needs, above-mentioned extraordinary backplate be made further optimization and/or improvements:
Shown in accompanying drawing 1,2, the right-hand member of left backplate 1 has right pin-and-hole 4, and the left end of right backplate 2 has left pin-and-hole, is set with bearing pin 5 in the left pin-and-hole, and the front portion of bearing pin 5 is sleeved in the right pin-and-hole 4.
Shown in accompanying drawing 1,2, the front side left part of right backplate 2 is fluted 10, and left pin-and-hole is positioned at concave station 10, and the right part of left backplate 1 is sleeved in the concave station 10.The right backplate 2 of concave station 10 tops can be realized left backplate 1 spacing what rotate around bearing pin 5.
