DEVICE (VERSIONS) AND PROCEDURE FOR DETERMINATION OF BOREHOLE PARAMETERS Russian patent published in 2011 - IPC E21B49/00 E21B47/00 

FIELD: oil and gas production.

SUBSTANCE: according to one version communication system for determination of borehole parameters consists of sensor plug positioned in orifice in borehole well. The system has a sleeve installed in the orifice of the borehole well, and a finger located in the sleeve. Also, the sleeve, moving into the sleeve, expands it, thereby the sleeve packs the orifice. The sleeve is equipped with a chamber; the finger at its end has a needle puncturing the chamber, when the finger is fed into the sleeve. The system is furnished with a sensor for measuring borehole parameters and with electron circuits connected with the sensor. The system is also equipped with a downhole tool arranged in the borehole and communicated with the sensor plug and a unit of surface. To implement the procedure for determination of borehole parameters the sleeve is installed in the orifice in a side wall of the borehole. The orifice is packed at feeding the finger into the sleeve. The sensor installed in the finger determines at least one borehole parameter. Also, there is a stage of the procedure providing a preliminary test.

EFFECT: upgraded quality and accuracy of measurements of borehole parameters.
