DEVICE AND METHOD FOR MEASURING DEPTH OF WELL AND DETECTING LIQUID IN IT WHEN PROVIDING BLASTING OPERATIONS Russian patent published in 2024 - IPC G01B7/26 E21B47/04 

FIELD: measuring equipment.

SUBSTANCE: present invention relates to measuring equipment and methods for measuring the depth of a well and determining the presence of liquid in wells when providing blasting operations. Device includes a mechanics module, an electronics module and a measuring probe. Mechanics module includes a drum with a flexible element and a motor, and the flexible element is connected to a tension sensor configured to determine the tension of the flexible element. Electronics module, in its turn, is connected to the mechanics module and includes a power supply and a control board. Measuring probe is fixed at the end of the flexible element and includes a liquid sensor in the electric circuit of which at least one contact is open. Control board is configured at least to receive data from the tension sensor and the fluid sensor and to determine the depth of the well.

EFFECT: providing the possibility of measuring the depth of the well and detecting the presence of liquid in the well with high accuracy and speed of measurement.
