FIELD: oil and gas industry. SUBSTANCE: method involves running a surface casing string into the well. Prior to running down the flow tubing, measures are taken to identify the borehole section where hydraulic fracturing of formation is likely at the operating pressure. After running down the flow tubing, the casing string-borehole annulus is filled with some solidifying permeable hard-skeleton material. This material is used to fill the section fraught with hydraulic fracturing. The casing string-borehole above this section remains free for liquid circulation. EFFECT: higher reliability. 1 dwg
