THERMAL GAS PRODUCER TO TREAT FACE ZONE OF PRODUCTIVE POOL OF OIL WELLS AND PROCESS OF ITS MANUFACTURE Russian patent published in 2002 - IPC

FIELD: oil and gas production. SUBSTANCE: thermal gas producer is furnished with thermally stable solid-fuel pots which enable gas producer to be used to treat wells with temperature up to 220 C across face. Solid-fuel pots are protected against exposure to well fluid by protective jacket into which fuel mass is put in process of pot manufacture. Pots are installed vertically one on another by face surfaces with the aid of assembling facility. Protective jackets are produced from combustible rubberized cloth, type 500E. Combustible elements of solid-fuel pots include oxidizer, fuel and technological additives. Pot is fitted with igniter with heating element and attachment unit. 12-27 mas.% of ethylenepropylene combustible binder, 70-80 mas. % of perchlorate oxidizer and 1-12 mas.% of functional additives are mixed at 30-50 C in the course of 1-1.5 h. Produced mass is vacuumed for 0.5-1.0 h, and is formed and subjected to gradual polymerization. EFFECT: development of effective multipurpose thermal gas producer. 2 cl, 2 dwg, 1 tbl
