ABSTRACT:
A retrievable packer for use in an oilwell casing, the packer having a central shaft with means at the upper end for attachment of an insertion or retrieval tool, an upper body portion having an opening receiving the shaft and having an integral downwardly extending tubular sleeve, the area around the sleeve providing an annular upper gland surface, a lower body portion having an opening receiving the shaft and a larger opening slidably receiving the sleeve and providing a lower annular flange surface, the lower body portion having a plurality of slots formed in vertical planes of the shaft axis, a baseplate having a threaded opening therein receiving the threaded lower end of the shaft, the baseplate serving to engage slips positioned in the slots so that as the shaft is rotated the baseplate moves up to force the slip into contact with the casing in which the packer is positioned, and an elastomeric packing gland of tubular cross-sectional shape received on the sleeve and between the upper and lower gland surfaces so that as the shaft is rotated the packing gland is compressed and radially outwardly expanded to seal the casing.
