FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil-producing industry and provided for receiving the information about geological formation, about casing pipe or about fluid in casing pipe. For this there are used requester and one or more sensing device in borehole. Requester is located in borehole, and it is usually implemented with ability of movement inside the borehole. Sensing device, which is fix installed in cut in casing pipe hole, allows body and vessel with corresponding electronics. Body of the sensing device is usually implemented with the ability of provision of hydraulic gate relative to hole in casing pipe. Requester and sensing device implement communication to each other by wireless method.
EFFECT: providing of on-line monitoring of cased boreholes parametres with simultaneous simplification of measurements.
