Probe packer and method of using same

摘要

A probe for forming a seal between a downhole tool and a wall of a wellbore, includes a probe inlet (120) extending from the downhole tool for fluid communication with a subterranean formation, a base (130) positionable about the downhole tool about the probe inlet, a packer (118) positionable on the base for forming a seal with the wellbore wall, and a raised packer support (342) and/or packer stopper (556) for supporting the packer as the packer is compressed against the wellbore wall. The packer may have an inlet channel (536) extending therethrough for receiving the probe inlet. The raised packer support can extend from the base for supporting the packer, and the packer may have a support channel extending a distance therein for receiving the raised packer support. The packer stopper can extend from the base about a perimeter of the packer with an expansion gap defined (562) therebetween.
