FIELD: oil-and-gas industry. ^ SUBSTANCE: invention related to pivotal propping agents preparation and application methods, also for additives preparation and application methods, which prevents borehole inflow, used for hydraulic fracturing operations. Cemented propping agent and additive, preventing borehole inflow, pivotal shaped have big strength and conductivity. Cemented pivots includes approximately from 0.2 up to 4% of aluminium titanat. In come cases manufacture cemented pivots by mixing bauxite and non-bauxite aluminium oxide sources, which can contain a few admixes, for instance TiO2 extruding the mixture and cementing it. A source material can be grained for better packing and resistance to crushing in final cemented pivot (optional). Hydraulic fracturing liquid may include only cemented pivots or in combination with propping agent, preferably with the propping agent of a different form. ^ EFFECT: propping agent conductivity and permeability increase, production cast cutting and well operation lifetime increase. ^ 63 cl, 2 tbl |
