| 摘要 | A milling system includes an elongate body having a first end, a second end, and a mill window defined through a portion of the body between the first and second ends. A mill is movably arranged within the body, and a whipstock assembly is arranged at least partially within the body and configured to guide the mill out of the body through the mill window in order to mill a casing exit. A torque sleeve is coupled to the body and extends over a portion of the body between the first and second ends so as to increase a torsional resistance of the body. | ||

| 主权项 | 1. A milling system, comprising: an elongate body having a first end, a second end, and an unobstructed mill window defined through a portion of the body between the first and second ends; a mill positioned within the body; a whipstock assembly arranged at least partially within the body and aligned with the mill window to guide the mill out of the body through the mill window to mill a casing exit through radially adjacent casing; and a torque sleeve coupled to an exterior of the body and extending over a portion of the body between the first and second ends to occlude at least a portion of the mill window and thereby increase a torsional resistance of the body. | ||
