DEVICE FOR THERMO-GAS-CHEMICAL TREATMENT OF PRODUCTIVE STRATUM Russian patent published in 1997 - IPC

Abstract RU 2071556 C1

FIELD: oil and gas industry. SUBSTANCE: by selecting mode of burning of powder charge in proposed device it is possible to ensure efficient thermo-gas-chemical treatment of productive stratum both close to bore hole (by high frequency oscillations) and at large distance from it (up to hundreds meters) in depth of productive stratum (by low frequency oscillations). Integrity of casing string and of cement stone around it is guaranteed. EFFECT: high efficiency. 5 dwg
