Abstract
The utility model discloses a double-acting stabilizer for reducing resistance and torsion which comprises a stabilizer body (1) and an outer sheath body (2) sheathed on the outside at middle part of the stabilizer body (1), wherein the stabilizer body (1) is formed by sequentially connecting an upper joint (11), a lower limiting mechanism (12), a through-hole (13), an upper limiting mechanism (14) and a lower joint (15); the outer periphery of the outer sheath body (2) is provided with a plurality of rolling devices (8) which comprise a rolling body containing device (9) and two rollers (83) and are axially provided with a plurality of rows of arranged six-array rollers in a staggered way; during the process of putting a drill string and drilling in, the drill string makes an axial movement, and then the original sliding movement is replaced with rolling movement, therefore, the sliding friction of the drill string in a well is led to become rolling friction, and simultaneously, the two ends of the rolling body containing device are provided with a smoothening reverse angle for guiding, thereby greatly reducing the friction of a down-hole drill string.
Description
Technical field
The utility model relates to oil downhole tool drilling well class, is specifically related to a kind of drilling tool stabilizer.
Background technology
Drilling tool stabilizer is rig indispensable parts in boring procedure, it generally comprises columniform body, there is the threaded line that is respectively applied for connection drill bit and drilling rod at the two ends of body, and the periphery of body is an anti-friction material, and the external size of its periphery is close with the external size of drill bit.It reduces rig vibrations and drilling rod moment of torsion to preventing hole scattering, and the prolongation drilling life of bit plays positive role.Anti-friction material is fixed in the body periphery in the prior art, is made generally in garden cylindricality or ribs shape.But the drilling well stabilizer of this kind structure is a sliding friction in lower going-into-well the time and around the borehole wall, thus in the drill string drilling process difficulty relatively, the load of drill string and rig also can be bigger, causes downhole safety to be effectively guaranteed.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of resistance that reduces is provided, and reduces the drilling tool stabilizer of friction.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of drag reduction falls turns round the double acting stabilizer, the outer sleeve body that comprises stabilizer body and the outside, middle part that is enclosed within the stabilizer body, the stabilizer body is connected in sequence by top connection lower limit mechanism, through hole, upper limit mechanism, lower contact, some tourelles are installed on the excircle of described outer sleeve body, and tourelle comprises rolling element storing apparatus and at least one roller.
Further technical scheme is:
Described rolling element storing apparatus two ends are provided with the level and smooth chamfering of guiding.And the roller of each rolling element storing apparatus the inside has two.
The utility model is all right: tourelle is set to six, is divided into two groups, and every triplets are installed in respectively on two cross section excircles of outer sleeve body.And be that trisection is installed on the excircle of place cross section, two groups of tourelles upwards are staggered in the footpath along the stabilizer body simultaneously.
Compared with prior art, the beneficial effects of the utility model are: this instrument is equipped with the many rows of dislocation six row rollers in the axial direction, creep into when rising that drill string axially moves in the process, this moment, roller replaced original slip to roll, thereby make the sliding friction of drill string in well become rolling friction, rolling element storing apparatus two ends are provided with the level and smooth chamfering of guiding simultaneously, have lowered underground drill stem frictional force significantly.
Description of drawings
Fig. 1 is the overall structure figure of the utility model embodiment 1
Fig. 2 be Fig. 1 along A-A ' to sectional view
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
Shown in Fig. 1 or 2, a kind of drag reduction falls turns round the double acting stabilizer, the outer sleeve body 2 that comprises stabilizer body 1 and the outside, middle part that is enclosed within stabilizer body 1, stabilizer body 1 is connected in sequence by top connection 11, lower limit mechanism 12, through hole 13, upper limit mechanism 14, lower contact 15, six groups of tourelles 8 are installed on the excircle of described outer sleeve body 2, and tourelle 8 comprises rolling element storing apparatus 9 and two rollers 83.Roller 83 can be installed in 9 li of rolling element storing apparatus by roller pin, and rolling element storing apparatus 9 two ends are provided with level and smooth chamfering, and six groups of tourelles 8 are divided into two groups, and every triplets are installed in respectively on the excircle of two cross sections of outer sleeve body 2.And each group all is that trisection is installed on the excircle of place cross section, and two groups of tourelles 8 upwards are staggered in the footpath along stabilizer body 1 simultaneously.
