Description
Technical field:
The utility model belongs to fastener areas, relates to the special tool in a kind of Process of Oil Well Drilling, specifically is the special-purpose anchor ear of a kind of sleeve pipe wearing bush.
Background technology:
In Process of Oil Well Drilling, along with reasons such as the increase of well depth or well track complexity, cause frictional resistance and/or wearing and tearing between drilling rod and the sleeve pipe to increase, it mainly shows as: 1, sleeve pipe heavy wear even worn out, can not pressure-bearing, bring a lot of difficult problems for follow-up construction operation etc., cause later stage completion difficulty, even serious consequence that can't completion; 2, the down-hole moment of torsion is big, causes the accident of drillling tool twisting off easily, causes the expense that increases drilling tool; 3, performances such as the collapsoing strength of casing string, internal pressure strength reduce, and the safety of sleeve pipe and well life-span caused have a strong impact on.Therefore, the assembling wearing bush is to overcome above-mentioned defective on sleeve pipe during operation, and wearing bush is fixed on the sleeve pipe by anchor ear.Anchor ear is made of the aluminium alloys body of two semi-annular shapes of butt joint, have two docking points, a docking point is an articulated structure, another docking point is a hatch frame, this open butt joint point is by the screw hole on the body and sealed with the suitable screw of this screw hole, because the aluminum alloy material of body, the intensity of screw hole is low, such anchor ear closing component structure causes screw hole and screw loosening in the use easily, cause sealed docking point to be thrown off, stable, poor stability have all brought inconvenience for preceding installation of operation and operation process.
Summary of the invention:
The purpose of this utility model provides that a kind of rigidity is sealed, anti-impact force is strong, the special-purpose anchor ear of the sleeve pipe wearing bush of long service life.
The utility model is realized its purpose by the following technical solutions:
The special-purpose anchor ear of a kind of sleeve pipe wearing bush, this anchor ear is made of two semi-annular shape bodies of butt joint, have two docking points, a docking point is that articulated structure, another docking point are hatch frame, this open butt joint point is by the screw hole on the body and sealed with the suitable screw of this screw hole, described body is an aluminum alloy material, and an end cylindrical wall of two semi-annular shape bodies of described butt joint is a cone structure, is inlaid with the screw silk braid of alloy steel material in the described screw hole.
Axial arranged on the inner round wall face of two semi-annular shape bodies of described butt joint have a runner that is groove, and this runner is the groove shape in the conoid end end of body.
Described runner is axially evenly arranged on body inner round wall face.
Described runner is the groove of " U " shape.
Described screw is the alloy steel material.
The tensile strength of described alloy steel is at 200KG/mm
2More than.
The docking point of described articulated structure is by two semi-annular shape bodies of bearing pin and the hinged butt joint of hinge plate.
Described hinge plate is at least one.
Described hinge plate is the structural carbon steel material.
Described aluminum alloy material is 6061 aluminium alloyss.
The beneficial effects of the utility model are: adopt said structure have simple in structure, dismounting is easy, easy to use, wear-resistant, anti-impact force strong and characteristics such as long service life, high-temperature resistant can reach more than 600 ℃, satisfies down-hole environment for use requirement fully.The fixing sleeve pipe wearing bush of this anchor ear can reduce the inlet turbulent flow, improves the runner performance, draws good fluidity, have good wear-resisting, water-fast, fungus resistance energy, and acid and alkali resistance or wet goods, good mechanical performance, it is specially adapted to the drillng operation of various mud types and different well types.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
Referring to Fig. 1 and Fig. 2: the utility model is made of two semi-annular shape body 1-1,1-2 of butt joint, the end cylindrical wall of two semi-annular shape body 1-1,1-2 of butt joint is a cone structure, axially evenly be furnished with the runner 2 that is " U " shape groove on body 1-1, the 1-2 inner round wall face, this runner 2 is the groove shape in the conoid end end of body 1-1,1-2.Body 1-1,1-2 select high-intensity forging and pressing aluminium alloys (i.e. 6061 aluminium alloyss) material for use, are processed into blank through moulding of mould extrusion stretching and heat treatment step during making, make through digital control processing again, adopt the electrophoresis mode to carry out surfacing.Semi-annular shape body 1-1, the 1-2 of these two butt joints have two docking points, docking point is by two semi-annular shape body 1-1, the 1-2 (bearing pin is hinged with an end and the body 1-1 of three hinge plates, and another root bearing pin is hinged with the other end and the body 1-2 of three hinge plates) of bearing pin 6 and three axial arranged structural carbon steel material hinge plate 3 hinged butt joints.Certainly, this articulated structure can also be other, and for example: need not hinge plate, two semi-annular shape bodies are shared a bearing pin etc.When the articulated structure of hinge plate was set, the quantity of hinge plate was decided according to the axial length (and height) of anchor ear, and the long more hinge plate of layout that needs of axial length is many more, and the short more hinge plate that need arrange of axial length is few more.Another docking point of two semi-annular shape body 1-1,1-2 is a hatch frame, this open butt joint point is by the screw hole on body 1-1, the 1-2 and sealed with the suitable screw 5 of this screw hole, screw 5 is the alloy steel material, because the aluminum alloy material of body 1-1,1-2, the screw hole intensity that processes is low, in use cause screw hole and screw loosening easily, cause sealed docking point to be thrown off, therefore, in screw hole, be inlaid with the screw silk braid 4 of alloy steel material, increase its intensity, make the closing component structure formation rigidity of body 1-1,1-2 sealed.The alloy steel of this screw silk braid 4, screw 5 is that tensile strength is at 200KG/mm
2Above alloy steel material.
