Directional drilling method (options)

Claims

1. A method of directional drilling, including the supply to a drilling tool with a downhole motor deflector and a bit of axial load and torques that ensure uneven rotation of the bit around the borehole axis or tangent to it, wherein the speed of rotation of the bit around the borehole axis or tangent to it during rock destruction in a given direction is set less than the speed of rotation of the bit around the borehole axis or tangent to it during rock destruction in a direction opposite to the given direction, characterized in that the change in the speed of rotation of the bit around the borehole axis or tangent to it during a half-turn corresponding to the given direction is carried out according to a sinusoidal law, and the change in the speed of rotation of the bit around the borehole axis or tangent to it during a half-turn corresponding to the direction opposite to the given direction is also carried out according to a sinusoidal law.

2. A method of directional drilling, which includes feeding an axial load and torque to a drilling tool with a downhole motor deflector and a bit, ensuring uneven rotation of the bit around the borehole axis or tangent to it, wherein the speed of rotation of the bit around the borehole axis or tangent to it during rock destruction in a given direction is set less than the speed of rotation of the bit around the borehole axis or tangent to it during rock destruction in a direction opposite to the given direction, characterized in that the speed of rotation of the bit around the borehole axis or tangent to it is inversely proportional to the rock's resistance to destruction.
