发明名称 METHOD OF DEVELOPMENT OF OIL POOL
摘要 oil producing industry, particularly, methods of intensification of oil displacement from oil formations for increase of well production rate. SUBSTANCE: method provides for injection of driving agent through injection wells and oil withdrawal from producing wells. Installed in interval of location of filter of producing well, being in interference with injection well, is bath of chemically active fluid and filter walls are subjected to mechanical treatment in this medium and after that, this well is subjected to vacuum treatment. Mechanical treatment is effected by device with rotating blades and executing reciprocating motions. Well washing is carried out also with device rotating blades. EFFECT: higher efficiency of method due to reduced terms of well cleaning from deposits. 3 cl, 4 dwg
