FIELD: mining.
SUBSTANCE: installation consists of depression chamber, of gate element of this chamber, of catcher and of plunger. According to the invention the installation has a head for a logging cable tip with a valve for excessive pressure relief, a module of radioactive survey for connecting the installation to well profile and a slime-receiving facility. The gate element of the depression chamber is made non-destructive, and has a gate with a fusing element and a heated spiral for heating the fusing element and for opening the gate element. The catcher has slit-like vertical cuts and a cone-deflector for concentrating hydraulic impact. Also to facilitate additional thermal influence onto bottomhole zone of the reservoir a powder charge can be secured to the installation. Insulated current conducting elements are installed in the plunger of the depression chamber and in the gate element.
EFFECT: increased reliability of installation operation and its expanded functions.
