Technology of Creation of Cracks in Well-Borehole Zone of Formation

The development of energy-saving technologies requires a new approach to intensifying oil production. The decline in well production rates in almost all oil and gas producing countries, as well as the commissioning of new oil fields with a complex geological structure, require new technological solutions to increase the permeability of the well bore zone of the oil reservoir. To penetrate low-permeability reservoirs, it is necessary to break the rock mass, creating a volumetric dense network of cracks. The existing technologies of mechanical action on the bottomhole zone either increase the pressure too slowly, which, when very high pressure is applied, leads to the formation of one crack, or with a rapid increase in pressure, they contribute to brittle crushing of the rock, but without developing cracks in the depth of the formation. It is desirable to use technology that can create cracks on the surface of the rock, and then fill them and develop them along the formation column in all directions. In addition, it is important that the proposed technologies are economical and have minimal damage to the environment.
