Abstract
The utility model belongs to the technical field of oil drilling equipment, and particularly relates to a drill pipe stabilizer which comprises an upper section, a stabilizer body and a lower section. The upper section is connected with a drill pipe, the stabilizer body is positioned in the middle, the lower section is connected with a drill bit, both the upper section and the lower section are cylindrical, threaded portions for connection are arranged at the ends of the upper section and the lower section, two spiral ribs are arranged on the outer wall of the stabilizer body, and a 10-degree included angle is formed between the spiral direction and the center line of the drill pipe stabilizer. The drill pipe stabilizer is simple in structure and fine in stabilizing effect.
Description
Technical field
The utility model belongs to the oil-well drilling equipment technical field, relates in particular to a kind of drill pipe stabilizer.
Background technology
Drill pipe stabilizer is rig indispensable parts in boring procedure, generally comprises a columniform body, and there is the threaded line that is respectively applied to connect drill bit and drilling rod at the two ends of body.Drill pipe stabilizer is to preventing hole scattering, the vibrations of minimizing rig and drilling rod moment of torsion and the effect of playing key application life that prolongs drill bit.
The utility model content
The utility model provides a kind of simple in structure, drill pipe stabilizer that stablizing effect is good for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: drill pipe stabilizer comprises the epimere that is connected with drilling rod, the stabilizer body and the hypomere that is connected with drill bit that is positioned at the middle part; Described epimere and hypomere are cylindrical, and are provided with for the threaded portion that connects in the end; The outer wall of described stabilizer body is provided with spiral helicine fin, and this fin quantity is two, and the center line angle of the hand of spiral and drill pipe stabilizer is 10 °.
Advantage of the present utility model and good effect are: owing to adopted above-mentioned design, the utility model is simple in structure, with drilling rod be connected with drill bit be connected convenient.By the quantity of optimization stabilizer body sidewall epirelief rib and the angle of spiral, promote the stablizing effect of drill pipe stabilizer.
