摘要：
A system and method for setting an anchor and/or whipstock attached to a downhole motor having a cutting tool attached to a tubular member, such as coiled tubing. In one aspect, the motor allows flow therethrough sufficient to actuate an upstream MWD or other position measuring tool, and an orienter if so equipped, and retain the orientation of the motor with the attached whipstock. An increased flow rate or pressure actuates the motor once the whipstock is set and rotation of the cutting tool or other equipment can begin.
