Beschreibung
Zusammenfassung:	FIELD: oil and gas production industry. SUBSTANCE: according to method, injected into clay-bearing reservoir through injection wells is magnetized water, and oil is recovered through producing wells. Water is magnetized by magnetic field with intensity of 300-450 Oe. Added to water before and after its magnetization are salts of polyvalent metals with concentration of 3-10 g/t. EFFECT: higher efficiency. 1 tbls
