Abstract
A device for orienting core samples relative to their position in the subsoil before extraction, attaching to a core bit during drilling features a robust tubular body with a detector to identify core sample breakage and orientation using triaxial accelerometers and gyroscopes, measuring orientation by the gravity vector or true north. An electronic control unit stores, timestamps, and transmits data wirelessly via BLUETOOTH®, ensuring data reliability without removing the device. The device includes adapters for different pipe diameters, minimizing the need for disassembly and reducing user fatigue, while maintaining pump functionality with a bypass valve if needed.
Claims12
A device for detecting the orientation of a core sample relative to a position thereof with respect to a 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 configured to detect a breaking of the core sample from the subsoil, and also configured to detect an orientation of the inner tube or of the core sample provided in the inner tube;
- and
- an electronic control unit arranged in the tubular body configured to control the detector and for receiving and processing data thereof relating to the breaking of the core sample and the orientation of the inner tube and/or the core sample placed in the inner tube, and to the wirelessly transmitting of the data, wherein the electronic control unit is also configured to store the data of the breaking of the core sample for further processing, and wherein the electronic control unit comprises a circular buffer configured to record the data related with the breaking of the core sample and a non-volatile memory configured to store said data, wherein the circular buffer has an adjustable frequency to record the data, wherein the frequency is adjusted among the range of 1 Hz to 0.2 Hz.
A system for detecting the orientation of a core sample relative to a position thereof with respect to a subsoil before being extracted, the system comprising:
- a device for detecting the orientation of the core sample;
- and
- a portable communication device for establishing wireless communication with the device, receiving an orientation data therefrom, processing the data and presenting the orientation data of the core sample to a user;
- wherein the device comprises:
- a tubular body couplable to an inner tube or to a head assembly of a core bit;
- a detector arranged in the tubular body configured to detect a breaking of the core sample from the subsoil, and also configured to detect an orientation of the inner tube or of the core sample provided in the inner tube;
- and
- an electronic control unit arranged in the tubular body configured to control the detector and for receiving and processing data thereof relating to the breaking of the core sample and the orientation of the inner tube and/or the core sample placed in the inner tube, and to the wirelessly transmitting of the data, wherein the electronic control unit is also configured to store the data of the breaking of the core sample for further processing, and wherein the electronic control unit comprises a circular buffer configured to record the data related with the breaking of the core sample and a non-volatile memory configured to store said data, wherein the circular buffer has an adjustable frequency to record the data, wherein the frequency is adjusted among the range of 1 Hz to 0.2 Hz.
