PROCESS OF TREATMENT OF PRODUCTIVE POOL AND CHARGING Russian patent published in 2001 - IPC

FIELD: oil production industry, treatment of face zone of pool. SUBSTANCE: thermal, gas, chemical, boric and vibration wave actions are used to act on productive pool by way of burning of solid-fuel charge in interval of seam. Acidic treatment of seam is conducted simultaneously with burning of charge. Hydrochloric acid is produced in the form of steam and gas mixture under high temperature and pressure exceeding intraseam values of these parameters directly from materials of solid-fuel charge. Mass of produced hydrochloric acid should amount to 20% of mass of charge as minimum. Components used to manufacture mixtures of solid fuels are utilized in the capacity of materials of charge. Water-soluble salts of perchloric acid, for instance, ammonium perchlorate bonded by combustible components in the form of rubber-like binder are used as oxidizer. Filling agent in the form of powder of burning stabilizer in the amount of not more than 1.5% of mass of charge is utilized. Ratio of length and diameter of central conduit depends on size and composition of charge, temperature and pressure in well. Distances between rows of radial through conduits depend on ratio of length and diameter of central conduit. EFFECT: improved filtration properties of productive pool, raised microjointing and substantially increased penetrability of pool. 5 cl, 1 dwg
