FIELD: geophysical research of wells.
SUBSTANCE: invention can be used to determine the technical condition of wells and the distribution paths of compositions using radioactive logging using labelled substances. The device contains a capsule with a labelled liquid, an initiation unit, and a geophysical cable with a cable tip. The capsule is made in the form of a cylindrical body, in the upper part of which there is a piston. The initiation unit is designed to be connected to the cable lug and includes a solid fuel generator connected through the tip and contact to the head of the cable lug and housed in a cylindrical housing mounted above the piston. At the bottom, the capsule is connected to an adapter, which is connected to the shank at the other end. The adapter has a valve mounted on shear screws, and in the middle part of the adapter there are grooves for the outlet of the labelled liquid.
EFFECT: simplified design, increased efficiency of well testing while reducing biological hazards and maintaining environmental cleanliness.
