Abstract

The packer is used in plugging operations and tests in geological exploration drillings. It may be used in horizontal, slanted and vertical drillings and is highly reliable with regard to the actuation of the packer of the preliminarily determined depth. It consists of a corpus (1), on which, from bottom to top, are located a check valve (2), and an elastic, externally-ribbed element (4), encompassed on both sides by pulleys (3 and 5). In the corpus is fastened a screw spindle (7) with a retaining-fixating mechanism formed in it, while in the top part of the spindle is located a cantered elastic plug (12). The spindle is connected to an end piece (13), encompassed by an adapter (17).
