FIELD: oil and gas industry.
SUBSTANCE: used in the study of wells to measure parameters in the pipe space of the well, operation, and carrying out geological and technical measures. The device contains a rod with radial holes and connecting threads made in it. An eccentric body is fixedly mounted on the rod, made in the lower part with end protrusions that fit into reciprocal grooves made on the outer protrusion on the rod. The body is limited by a coupling and an outer protrusion on the rod; together with the rod it forms a sealed chamber for housing one or more autonomous devices. The chamber communicates with the rod cavity through radial holes on the rod.
EFFECT: additional loads on the rod are eliminated, and autonomous devices are protected from the negative effects of well fluid in the annulus and mechanical damage.
