FIELD: oil and gas industry.
SUBSTANCE: method includes preparation of technological liquid - water solution of sylvinite ore mixture with chlorine calcium by solving a mixture of components in hot fresh technical water, drained from oil and water preparation plants or bed water. During solution of sylvinite ore mixture with chlorine calcium in bed water the latter is drained from the well at temperature 60-90°C. Technological liquid is produced with solution density 1.23-1.37 t/m3. Then prepared technological liquid is fed into well shaft a bit lower, oppositely to zone and above ceiling of productive bed with forming of hydraulic column above the latter. Then well shaft to the mouth is filled with water. Value of technological liquid hydraulic column of high density on basis of said mixture, fed into well shaft above ceiling of productive column of technological liquid is taken in amount, necessary and enough from well stopping conditions.
EFFECT: higher efficiency.
