Beschreibung
Zusammenfassung:	oil producing industry, particularly, compositions for waterproofing operation; applicable in regulation of filtration flows of oil formations. SUBSTANCE: composition contains the following amounts of components, wt. %: aluminium chloride 10-15; zinc chloride 10-15; carbamide 35-55; the balance, water. EFFECT: higher efficiency of composition due to regulation of its physico-chemical characteristics (time of gel formation and viscosity), extended field of application, reduced cost of composition and solved ecological problem - utilization of wastes of petrochemical processes. 2 tbl, 3 ex
