Device and system for orienting core samples

Abstract

A device for orienting core samples relative to the position thereof with respect to the subsoil before being extracted is intended to remain coupled during operation in a core bit, that is, in the bit used to drill and extract the core sample from the subsoil. The proposed device includes a tubular body couplable to an inner tube and/or to a head assembly of a core bit, detector is arranged in the tubular body configured to detect the orientation of the inner tube and/or of a core sample provided in said inner tube, and an electronic control unit arranged in the tubular body configured to receive and process data from the detector relating to the orientation of the inner tube and/or the core sample provided in the inner tube, and configured to wirelessly transmit the data.

1 . A device for orienting core samples relative to a position thereof with respect to the subsoil before being extracted, the device comprising:
 a tubular body couplable to an inner tube or to a head assembly of a core bit;   a detector arranged in the tubular body for detecting the orientation of the inner tube or of a core sample provided in the inner tube, and   an electronic control unit arranged in the tubular body for receiving and processing data from the detector relating to the orientation of the inner tube or the core sample provided in the inner tube, and wirelessly transmitting data.   
     
     
         2 . The device according to  claim 1 , wherein the control unit comprises a communicator configured for the wireless transmission of data using high-speed Bluetooth protocol. 
     
     
         3 . The device according to  claim 1 , wherein the detector comprises a set of triaxial accelerometers, arranged mutually orthogonal to each other, configured to orient the core sample by measuring the gravitational vector. 
     
     
         4 . The device according to  claim 1 , wherein the detector comprises a set of micromechanical gyroscopes arranged mutually orthogonal to each other, configured to orient the core sample with respect to true north. 
     
     
         5 . The device according to  claim 1 , further comprising an inner tube adapter configured to couple the tubular body to the inner tube. 
     
     
         6 . The device according to  claim 1 , further comprising a head adapter configured to couple the tubular body to the head assembly. 
     
     
         7 . A system for orientating core samples relative to a position thereof with respect to the subsoil before being extracted, the system comprising:
 a device for orienting core samples; and   a portable communication device for establishing wireless communication with the device, receiving data therefrom, processing the data and presenting the orientation data of the extracted core sample to a user;   where the device comprising
 a tubular body for coupling to an inner tube or to a head assembly of a core bit; 
 a detector arranged in the tubular body for detecting the orientation of the inner tube or of a core sample provided in the inner tube. 
   
     
     
         8 . The system of  claim 7 , wherein the communication device is configured for the wireless transmission of data using high-speed Bluetooth protocol. 
     
     
         9 . The system of  claim 7 , wherein the detector comprises a set of triaxial accelerometers, arranged mutually orthogonal to each other, configured to orient the core sample by measuring the gravitational vector. 
     
     
         10 . The system of  claim 7 , wherein the detector comprises a set of micromechanical gyroscopes arranged mutually orthogonal to each other, configured to orient the core sample with respect to true north. 
     
     
         11 . The system of  claim 7 , further comprising an inner tube adapter configured to couple the tubular body to the inner tube. 
     
     
         12 . The system of  claim 7 , further comprising a head adapter configured to couple the tubular body to the head assembly.
