SOLID-FUEL GAS GENERATOR WITH CONTROLLABLE PRESSURE PULSE FOR STIMULATION OF WELLS |
摘要 |
oil and gas production, mining industry. SUBSTANCE: invention is intended for fracture and thermal gas-chemical treatment of face zone of pool by gaseous products of burning of solid rocket fuel to intensify recovery of mineral resources such as oil and gas from coal formations and of metals mined by method of underground leaching. Solid-fuel gas generator provides for rise of rate of growth of pressure of powder gases with time and for efficient action on formation thanks to employment of armored and non-armored charges of different configuration taken in certain proportion, thanks to increase of their total number and thanks to use powerful high-speed igniters. Solid- fuel gas generator includes powder tubular armored charges, ignition charge placed under them and load-bearing geophysical cable with members for attachment of structure. Non-armored tubular charges are positioned between ignition charge and armored charges. Their number with reference to number of armored charges is determined by formulas. EFFECT: increased functional efficiency of solid-fuel gas generator. 4 cl, 4 dwg
