Design of the cutting modes of the "Window" in the casing and analysis of the interaction of the bottom of the drill string with the deflecting device

The article deals with ensuring the timely exit of the cutting tool behind the string and obrataining a window of a full profile according to the geometry of the deflecting surface of the deflector and preventing possible reorientation of the deflector in the well and related complications related to the process of interaction of the bottom of the drill string with the deflecting device. To solve these problems, it is necessary to analyze the process of the cutting tool with the deflecting device, which allows developing measures to reduce the forces that contribute to possible complications when cutting a window in the casing string.
