SYSTEM AND METHOD FOR DETERMINING POSITION WITHIN A WELLBORE |
摘要 |
A method of locating a wellbore feature, comprising delivering a mechanical position determination tool into the wellbore, selectively causing an undulating curvature of the mechanical position determination tool in response to a change in a fluid pressure, moving the mechanical position determination tool along a longitudinal length of the wellbore, and sensing a change in resistance to continued movement of the mechanical position determination tool. A mechanical position location tool for a wellbore, comprising pressure actuated elements configured to cooperate to selectively provide an unactuated state in which the mechanical position location tool lies substantially along a longitudinal axis and the pressure actuated elements further configured to cooperate to selectively lie increasingly deviated from the longitudinal axis in response to a change in pressure applied to the mechanical position location tool. |
