DEVICE FOR RESERVOIR EXPOSING AND FOR GAS-DYNAMIC, VIBRO-WAVE AND HYDROCHLORIDE RESERVOIR TREATMENT

摘要

FIELD: oil production, particularly perforating-explosive operations in well. ^ SUBSTANCE: device comprises hollow carrier shaped-charge perforator with head, sealed side orifices, hollow charges and tip. Device also has two sealed air chambers with charges arranged inside them. The charges are shaped as cylinders provided with central channels. Ratio between cylindrical channel section to diameter thereof is (6...28):1. Charges are of knock-free type and made of gas-generation composition including the following components (% by weight): polydivinylisoprene rubber with end epoxy groups - 7-9; transformer oil - 5.6-6.5; titanium disilicide - 0.6-1.5; strontium carbonate - 0.1-0.5; combustion modifier - 0.2-0.3; aromatic amino acids - 0.03-0.11; aromatic amine - 0.01-0.06; curing agent - 0.01-0.1; remainder is sal ammonia. ^ EFFECT: improved stimulation of oil production. ^ 2 dwg
