METHOD OF THE ROCKS PRESSUROMETER TESTING Russian patent published in 2018 - IPC E21C39/00 

FIELD: drilling of soil or rock.

SUBSTANCE: invention relates to the wells studying method and can be used to determine the rocks physical and mechanical properties in their natural occurrence. Method comprises loading the well walls with the increasing pressure steps by supplying of the fluid predetermined amounts to the pressurometer probe. Measuring the changed pressure and the well walls displacements. At that, the well walls loading is carried out in the interval containing the hydrofracturing closed fracture. This fracture is opened by increasing the loading pressure and using the measured hydrofracturing fracture opening pressure in calculating of the rocks deformation properties.

EFFECT: technical result consists in increase in the open wells pressurometer studies informativeness and reliability with obtaining additional information about the rocks physical and mechanical properties in their natural occurrence.
