PROCESS OF TREATMENT OF FACE ZONE OF PRODUCTIVE POOL OF GAS WELL Russian patent published in 2002 - IPC

FIELD: mining industry. SUBSTANCE: invention specifically refers to technology of treatment of face zone of productive pool joined by low-penetrability clayey terrigenous rock in deep wells producing gas. Moisture-removing agent- methanol which moves to face of well due to density higher than density of gas, into interval of occurrence of productive pool is pumped into hole clearance on well-head. Under action of capillary-diffusion forces it uniformly saturate rock of face zone of pool dissolving water. Agent enriched by water is removed from pool by blow-through of well. EFFECT: uniform impregnation of rocks of face zone of productive pool with moisture-removing agent, removal of water-enriched agent from well to relieve rocks of face zone of productive pool of water blockade and to enhance gas penetrability of collector-pool. 2 dwg, 2 tbl
