Beschreibung
Zusammenfassung:	FIELD: oil and gas industry. ^ SUBSTANCE: invention is applicable to the oil producing industry and can be of use for reclaiming earth storages containing drilling waste generated during well drilling. The method includes cleaning storage water by coagulation, precipitating and pumping it out; building up generated sediment and removing it to cluster site and motor road slopes; backfilling storages with earth and subsequently sowing grass. Cement is used as coagulant at 20-50 kg/m3 of storage water; sediment is built up by encapsulating and holding it for at least 20 hours; and storages are backfilled with earth after being completely emptied. ^ EFFECT: more efficient earth storage reclamation and improved environment. ^ 1 dwg
