INTEGRATED LOGGING TOOL Russian patent published in 2013 - IPC E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: tool contains sectional case with installed collar locators (CL), gamma-ray loggers (GRL), pressure sensors (P), temperature sensors (T), humidimeter (W), thermoconductive flowmeter (TCF) and resistivity metre (RM) from top downward; in pressurised portion of the case there are GRL, LM and P sensors at that sensitive membrane of P sensor is connected to environment by hydrochannel, while T sensors, W, TCF and RM are located in pressurised cavities of non-pressurised portion of the case. At that T and W sensors are shifted in relation to longitudinal axis of the device at equal distances and are installed in the case at place with two pairs of mutually perpendicular reach-through windows having different width and equipped with cross bulkheads, at that the device is equipped with flowmeter module consisting of centraliser, liner, body and metre run with RPM sensor and rotation direction sensor installed along axis of the body. In the upper part of the device there is also force sensing device, and between the device and flowmeter module there is an additional docking device with clamper and double-hinged mutually perpendicular electroconductive unit with offset of rotation axes in relation to longitudinal axis of the device; the device is equipped with additional three dimensional module or humidimeter (W) or thermal moisture tester (T-W) or viscometer (V).

EFFECT: improving operational performance of the device and expansion of its application area.
