The existing oil field drilling tool stabilizer is designed more traditionally, the connecting part of the existing oil field drilling tool stabilizer, a drill rod and a drilling tool is mostly in threaded connection, and the rotating connecting part is easy to loosen, so that the existing oil field drilling tool stabilizer cannot work normally.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides an oil field drilling tool stabilizer, adopts bolt formula connection structure, improves and is connected the steadiness with drilling rod and drilling tool, and the use is got up the disagreement and is taken place not hard up, has improved job stabilization nature.
In order to achieve the above object, the present invention provides the following technical solutions:
this oil field drilling tool stabilizer includes that cylindrical and outer wall attack the spiral post that has the spiral line, spiral post both ends are equipped with pipe-shaped left side installation pipe and right installation pipe respectively perpendicularly, the spiral post, left side installation pipe, right side installation pipe is all coaxial, the inner wall of left side installation pipe and right installation pipe all is equipped with the one deck gasket pipe, the jack has all been opened to the side of left side installation pipe and right installation pipe, all run through in the jack of left side installation pipe and right installation pipe has a bolt, all be furnished with mutual screw-thread fit's nut on two bolts.
As a further optimization of the present solution, the screw column is made of stainless steel.
As the further optimization of the technical scheme, the left installation pipe and the right installation pipe are both made of stainless steel and are connected with the spiral column through welding.
As a further optimization of the technical scheme, the sealing gasket pipes are all made of rubber materials and are connected with the inner walls of the left mounting pipe and the right mounting pipe through bonding agents.
As a further optimization of the technical scheme, the bolt and the nut are both made of stainless steel.
The beneficial effect of adopting above technical scheme is: this oil field drilling tool stabilizer can insert the connecting rod of drilling rod and drilling tool during left side installation pipe and right installation pipe when using, lets the mounting hole of connecting rod and the jack of left side installation pipe and right installation pipe align. Then the two bolts respectively pass through the left mounting pipe, the right mounting pipe and the connecting rod, and the nuts are screwed to achieve the purpose of connection. So connect more firm, not hard up when can effectively preventing to rotate. This oil field drilling tool stabilizer adopts bolt formula connection structure, improves and is connected the steadiness with drilling rod and drilling tool, and it is not agreed to take place not hard up to use, has improved job stabilization nature.

Detailed Description
The preferred embodiments of the oil field drilling tool stabilizer of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 and fig. 2 show the embodiment of the oil field drilling tool stabilizer of the present invention:
combine fig. 1 and fig. 2, this oil field drilling tool stabilizer includes that cylindrical and outer wall attack the spiral post 1 that has the spiral line, 1 both ends of spiral post are equipped with pipe-shaped left side installation pipe 2 and right installation pipe 3 respectively perpendicularly, spiral post 1, left side installation pipe 2, right side installation pipe 3 is all coaxial, the inner wall of left side installation pipe 2 and right installation pipe 3 all is equipped with the sealed pad pipe 4 of one deck, jack 7 has all been opened to the side of left side installation pipe 2 and right installation pipe 3, all run through a bolt 5 in the jack 7 of left side installation pipe 2 and right installation pipe 3, all be furnished with mutual screw-thread fit's nut 6 on two bolts 5.
The screw column 1 is made of stainless steel, and is firm, durable and good in corrosion resistance. Left side installation pipe 2 and right side installation pipe 3 are made by the stainless steel, and are sturdy and durable, and corrosion resisting property is good, and left side installation pipe 2 and right side installation pipe 3 all are connected with spiral column 1 through the welding. The sealing gasket pipe 4 is made of rubber materials, the elasticity is good, the sealing performance is good, and the sealing gasket pipe 4 is connected with the inner walls of the left installation pipe 2 and the right installation pipe 3 through the bonding agent. The bolt 5 and the nut 6 are both made of stainless steel, and are firm, durable and good in corrosion resistance.
This oil field drilling tool stabilizer can insert the connecting rod of drilling rod and drilling tool in left side installation pipe 2 and right installation pipe 3 when using, lets the mounting hole of connecting rod and the jack 7 of left side installation pipe 2 and right installation pipe 3 align. The sealing gasket pipe 4 can tightly wrap the connecting rod, and the connection tightness and the stability of the drill rod, the drilling tool and the oil field drilling tool stabilizer are good. Then, the two bolts 5 respectively penetrate through the left mounting pipe 2, the right mounting pipe 3 and the connecting rod, and the nuts 6 are screwed to achieve the purpose of connection. So connect more firm, not hard up when can effectively preventing to rotate. This oil field drilling tool stabilizer adopts bolt formula connection structure, improves and is connected the steadiness with drilling rod and drilling tool, and it is not agreed to take place not hard up to use, has improved job stabilization nature.
The stabilizer of the oil field drilling tool mainly plays a role in pointing and righting in the drilling tool assembly, the installation position of the stabilizer controls the well inclination angle and the borehole curvature within a specified range, most of the weight of the drill collar is concentrated on a drill bit, and non-borehole central force and other external force borne by the drill string and the drill bit are reduced. With the development of stabilizers and the mass production of horizontal and directional wells, stabilizers have become an indispensable bottom hole tool in modern wellbore trajectory control technology.
The stabilizing function of the oil field drilling tool stabilizer is mainly to reduce radial and axial violent vibration of a drill string elastic system in a hole; the eccentric wear of the drill bit and the drill rod is reduced; the coring quality is ensured; preventing well deviation or using manual directional drilling. The stabilizer is of a relatively simple construction and is a large diameter joint with rib segments (straight or helical).
The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept, and these all fall into the protection scope of the present invention.
