FIELD: oil industry, possible use during thermo-cyclic treatment of collector rock during processing of face-adjacent zone of bed.
SUBSTANCE: in accordance to method during processing of face-adjacent bed zone with sand collector, heating and cooling are performed cyclically. Heating is performed during 1,5-2,5 hours up to temperature of 80-90°C, cooling - during 0,5-0,75 hours up to temperature of 20-25°C. Number of cycles is set equal to 5-10.
EFFECT: increased efficiency of processing due to increased porosity and penetrability of productive bed collector.
