METHODS AND SYSTEMS FOR DRILLING BOREHOLES IN GEOLOGICAL FORMATIONS Russian patent published in 2020 - IPC E21B44/02 

Abstract RU 2732288 C1

FIELD: soil or rock drilling; mining.

SUBSTANCE: invention relates to drilling of wells. In particular, disclosed is a system for drilling in a geological formation, comprising: a drill bit for drilling a geological formation; drilling string; drill winch; a first sensor operatively coupled to the drill string, wherein the first sensor is configured to determine the rotation speed of the drill string; a second sensor operatively coupled to the drill string, wherein the second sensor is configured to determine the drill string driving speed when driving the drill bit for drilling a geologic formation; and a control unit operably coupled to the first and second sensors and the drill string. Control unit has a data processing unit and a long-term memory functionally connected to the data processing unit. Data processing unit is programmed to: determining the instantaneous cutting depth of cutting elements of the drilling bit for drilling a geological formation using the measured rotation speed of the drill string and the measured speed of the drill string advance using the corresponding algorithm; comparing instantaneous average cutting depth with preset minimum cutting depth stored in long-term memory; and to increase axial load on drilling bit for drilling of geological formation by means of drilling winch, when instant average depth of cutting is less than specified minimum cutting depth.

EFFECT: technical result is reduced duration of drilling, reduced amount of supplied energy, reduced wear and improved ability to respond to drilling conditions in real time.
