FIELD: oil-and-gas production.
SUBSTANCE: invention related to methods of underground reservoir treatment. At one version it referred to hydraulic fracturing of underground reservoir part, which includes thicken fluid use for reservoir treatment, which contains one salt water solution, with density greater than 9 pounds per gallon, and bonded thickener, and creating contact of underground reservoir part with mentioned above fluid for generation or expansion one or number of cracks, mentioned fluid in to bore hole, which passes though underground reservoir part, on which hydraulic fracturing applied, at surface pressure less than approximately 25000 pounds per square inch. In other versions the invention related to method of underground reservoir crack filling in and method of surface pressure decrease, necessary for creation of one or number of cracks in underground reservoir part. Invention develops in formula subclaime.
EFFECT: surface pressure decrease, which is necessary for creation of one or number of cracks and equipment accessibility accordingly, hydraulic fracturing and crack filling in expense cutting.
