The proposed method for processing the productive formation in a bottom-hole zone of a well (1) comprises heating the liquid in the bottom-hole zone of a well (1) and removing clogging products therefrom. In accordance with the technical solution, the upper part of the bottom-hole zone of the well (1) is sealed before heating the liquid, thus forming a bottom-hole chamber (6), and after the heating, the liquid within the volume of the bottom-hole chamber (6) is cooled and then this chamber (6) is unsealed before removing the clogging products therefrom. In the proposed packer (4) for processing the productive formation in the bottom-hole zone of a well (1), comprising a body (10) with a means for radial compaction in the form of sliding cheeks, a cup-type seal (15) and a drive, and a suspension means (2), in accordance with the technical solution, the lower end face (5) is made in the form of a concave surface of the second order. A method for fixing a packer (4) in a well (1), comprising lowering it into the well (1) to a required depth, increasing the diametral size of the packer (4) and deforming its cup-type seal (15) in a radial direction, wherein in accordance with the technical solution, the packer (4) is subjected to temperature action different from the temperature of the well liquid at the point of its installation. 19 dependent claims, 15 drawings.
