FIELD: oil-and-gas production. ^ SUBSTANCE: invention related to oil-and-gas production, particularly to production wells exploration and control systems. Sensor itself consists of case, sensor elements, which pensive stratum properties, and network elements, transferring information between sensor elements and network device installed in the well. Sensor case includes zone, which can be hermetically sealed into casing string or into tubing string in order to avoid fluid exchange between internal and external parts of casing string or tubing string. Sensors can include sensors for pressure, temperature, specific resistance, electro conductivity, voltage, deformation, pH , and chemical composition. Sensors to be installed into hole made in casing string or tubing string, in the way that it is able to pass between internal and external parts of casing string or tubing string, and seal hermetically. ^ EFFECT: increase in data communication efficiency. ^ 35 cl, 23 dwg |
