PROCESS OF DEVELOPMENT OF OIL FIELD OF CRACK-POROUS TYPE Russian patent published in 1994 - IPC

FIELD: oil production. SUBSTANCE: prior to start of initiation of process of interseam burning easily oxidized plugging compound is pumped into seam which volume amounts to 20-100% of volume of cracks of collector. After initiation of burning pumping of oxidizer is started. If take-up capability of injection wells is low then heat-transfer agent is pumped into production wells up to break before pumping of plugging compound. With low plugging fluidity, large opening of cracks and insufficient penetrability of blocks pumping of heat- transfer agent and of plugging compound is conducted in cycles. Plugging compound is pumped in amount of 5-20% of volume of pores of seam. Plugging compound is forced with heat-transfer agent to zone of burning and process of interseam burning is performed till gases from burning break into production wells through cracks. After this cycle is repeated. EFFECT: enhanced efficiency of development process. 3 cl
