Abstract
The probe is used in building of cement bridges in boreholes and in carrying out other plugging operations in them when the conditions do not allow the use of the known methods, as well as/and in the investigation of hydrogeological and technical boreholes. The probe is highly reliable and establishing, locking and packering of a preset depth without any contact with the face of the borehole and in widening of its average balanced diameter in depths towards the rated diameter of drilling under the last cemented casing column in the range of several-fold, and regardless of the lateral and longitudinal profile of its wall. The probe of the artificial face includes, from down-upwards: a stem (1), hollow elastic element (3), engaging the stem (1) along its length and fixed to it, reversible valve (2) and supporting device (4), connected to the stem (1). The device (4) is connected with a borehole rod (5). 1 claim, 4 figures
