高强震动酸化工艺技术在河南油田的推广应用
Application of Strong Vibration Acidizing Technology in Henan Oil Field
摘要
Abstract
Strong vibration acidizing technology was applied in Henan oilfield because of the heterogeneity, low permeability and serious popullation near wellbore zone of the reservoir in the oilfield. The technology combines physical plug removal with chemical acidizing, and it has better effectiveness and longer valid period than conventional acidizing technology. The technology was applied in 36 wells (29 water injection wells, 7 oil wells), success percentage reaches to 100%, effectiveness percentage reaches to 90.62%, the increase of water injection rate accumulates 44万m3, and average valid period reaches to above 8 monthes. The results of the field tests show that the technology has a good and soon result of plug removal for water injection wells and oil wells, and it is espectically suited to the treatment of the oil sandbody updip pinch out reservoirs which have bad physical property.关键词
