摘要
压裂作为重要的增产措施,在压裂作业中压裂液破胶不彻底导致返排量低,粘稠的压裂液及残渣会引起储层暂时甚至永久性的伤害,保护油层和防止地层伤害是提高产量的重要前题。针对榆树林油田压裂液配方体系,开展了适用于榆树林油田的压裂液的生物破胶剂现场试验。
As an important stimulation, fracturing fluid gclbreaker operations＂ un-complete will cause a low viscous fracturing fluid and debris may bring temporary or even permanent damage to the reservoir. Protecting the reservoir and preventing formation damage is an important premise to increase output. According to Yushulin oil and field fracturing fluid system, the field test of fracturing fluid bio-enzyme gelbreaker which is suitable for Yushulin oilfield is developed.
