METHOD OF HIGH-VISCOSITY OIL POOL DEVELOPMENT |
摘要 |
FIELD: mining. ^ SUBSTANCE: method involves positioning injection wells between production wells at the distance of 30-250 m between wells. Injection well bottom is positioned at 5-7 m distance from productive formation bottom. Production well bottom is positioned at 0.5-1.5 m distance from productive formation bottom. The wells are perforated at 0.6-1.0 m interval from the bottom. Steam alternated with air is used as heat carrier. Heat carrier is pumped over injection wells, and oil is withdrawn over production wells. ^ EFFECT: increased oil yield of a pool. ^ 1 ex, 1 dwg |
