SYSTEM AND METHOD FOR MAINTAINING POSITION OF A WELLBORE SERVICING DEVICE WITHIN A WELLBORE |
摘要 |
<p>A method of maintaining a location of a wellbore servicing device includes connecting a pressure activated hold-down tool (PAHT) to the wellbore servicing device, delivering the wellbore servicing device and the PAHT into a wellbore, selectively increasing a curvature of the PAHT in response to a change in a fluid pressure, and engaging the PAHT with a feature of a wellbore to prevent longitudinal movement of the wellbore servicing device. A PAHT has pressure actuated elements that selectively provide an unactuated state in which the PAHT lies substantially along a longitudinal axis and the pressure actuated elements selectively lie increasingly deviated from the longitudinal axis in response to a change in pressure applied to the PAHT. At least one of the pressure actuated elements has a tooth configured for selective resistive engagement with a feature of the wellbore.</p> |
