Method and apparatus for setting an inflatable packer
Patent
·
OSTI ID:5568518
This patent describes an apparatus for setting inflatable elastomeric packer sealing elements selectively positionable in a subterranean well bore by a wireline and radially movable for sealing engagement within the well bore in response to fluid pressure. The apparatus consists of: pressure generating means suspended in the well bore by the wireline for pressurizing a liquid within a liquid chamber of the generating means; pressure transmitting means having a fluid passage way in fluid communication with the liquid chamber for transmitting liquid pressure from the liquid chamber to the elastomeric packer sealing elements for moving the element into sealing engagement with the well bore check valve means for automatically closing the passageway in response to a decline in liquid pressure in the passageway; and pressure relief means in fluid communication with the passageway for relieving liquid pressure to the elastomeric packer sealing elements in excess of a selected level.
