STABILIZING ASSEMBLY FOR DRILLING Russian patent published in 2023 - IPC E21B7/04 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to the field of directional drilling of wells, namely to devices for stabilizing the direction of the wellbore and reducing the intensity of the natural curvature of wells. The stabilizing assembly for drilling contains a diamond bit with an eccentricity of the cutting part of the matrix end and a drill pipe with a displaced centre of mass of the cross section, containing remote segments. A diamond bit with an eccentricity of the cutting part of the die end and a drill pipe with a displaced centre of mass of the cross section are located in the assembly in such a way that half of the end of the matrix of the diamond bit with an eccentricity of the cutting part of the die end with a smaller area is placed so that its geometric centre is at 180° with respect to the geometric centre of the remote segments.

EFFECT: increased stabilizing ability of the drilling assembly.
