SYSTEM AND METHOD OF MEASUREMENTS DURING DRILLING Russian patent published in 2020 - IPC E21B47/12 G01V3/18 

FIELD: drilling of wells.

SUBSTANCE: invention relates to means of directional wells drilling. In particular, disclosed is a system of measurements during drilling (MDD) for use in a drill string. MDD system comprises: module for measurement of specific resistance; bit-sub configured to generate information relating to information on drill string drill bit inclination; MDD module; a first wireless communication module configured to send wirelessly information on resistivity from a module for measuring resistivity to an MDD module; and a second wireless communication module configured to wirelessly send inclination information from the bit-sub module to the MDD module. At that, the MDD module is configured to participate in transmission of information on inclination and information on specific resistance to the upper surface of the formation. A first wireless communication module comprises a short-distance receiver electrically connected to the MDD module, and a short-distance transmitter electrically connected to the resistivity measurement module.

EFFECT: technical result is prolongation of service life of tool due to reduction of mechanical stresses due to tools bending during drilling.
