stabilizer (stabilizer; balancer) also known as centralizer, is a tool that stabilizes downhole drilling tools and acts as an anti-tilt tool. A device attached to a string of drill pipe near a coarse diameter drill tool to stabilize the drilling direction is an important tool to prevent the deviation change in oil, natural gas and geological exploration drilling engineering.
Feature
Control borehole trajectory: The stabilizer mainly plays a pointing and righting role in the drill assembly, and the position of the stabilizer installation controls the inclination Angle and borehole curvature within the specified range, and also makes the vast majority of the weight of the drill collar concentrate on the bit, reducing the non-borehole force and other external forces borne by the drill string and the bit. With the development of stabilizer and a large number of horizontal Wells and directional Wells, stabilizer has become an indispensable bottomhole drilling tool in modern borehole trajectory control technology.
Reaming function: in the curved hole or hole reduction, it is drilled together with the drill string, and its lower end body and the chamfering of the working section transition play a certain reaming role.
Wall repair: In the process of friction contact between the stabilizer and the wall, it has different degrees of dressing effect on the wall, making the wall more smooth and smooth, and improving the quality of the well.
Effect
The stabilization function of the stabilizer is mainly to reduce the radial and axial vibration of the elastic system of the drill pipe string in the hole. Reduce bit and drill pipe bias wear; Ensure core quality; Prevent deviation or manual directional drilling. The structure of the stabilizer is relatively simple, and it is a coarse joint with a rib plate (straight or spiral). The form of stabilizer can be divided into drill string type and bottom hole type.
Structure type
● According to the installation position: Drill string type, bottom hole type.
● According to the assembly structure: integral, package and detachable
● According to the shape of the righting edge: spiral, straight edge and skew straight edge
● Others, such as replaceable sleeve stabilizers, are composed of a main body, a stability sleeve, and a sheath. Improve service life by replacing the righting sleeve to adapt to different diameters.
There are four kinds of wear-resistant materials on the stabilizer working surface:
● Cemented carbide column on the surface;
● Diamond complex embedded on the surface;
● Low temperature surface brazing carbide block;
● surfacing wear-resistant electrode.
