FIELD: oil and gas industry.
SUBSTANCE: group of inventions relates to the oil and gas industry, in particular to the determination of fluid properties in wells. The sensor array contains a set of connected sensors, wherein at least one of the sensors is at least partially enclosed in a casing, and an immersion tube outgoing the casing. The immersion tube is capable of creating a hydraulic connection between at least one of the set of connected sensors, which is at least partially enclosed in the casing, and the corresponding sensor channel. At least one of the specified set of connected sensors has a set of detector channels, and at least one set of the set of detector channels is covered with the casing, and at least one set of the set of detector channels is not covered with the casing. The set of sensors is connected by means of an electrically conductive cable. The immersion tube is located on a bobbin connected to the specified at least one of the specified set of connected sensors, which is at least partially enclosed in the casing.
EFFECT: accuracy and reliability of measurements are increased.
