摘　　要：根据陇东油田的油层物性、储层特征及敏感性分析,从酸化液入手,对增产增注过程中油层伤害的因素进行分析探讨,对减少油层伤害的酸化液进行室内评价,研制了系列保护油层的酸化液体系,在提高措施效率及减少油层伤害方面取得了较好的效果,并在现场得到了应用。Based on the reservoir characteristics and sensibility analysis of Longdong oilfield, the paper analyzed the factors of reservoir damage in increase productivity and injection increase, evaluated the acidizing fluid performance for reducing reservoir damage, developed a series of acidizing fluid system of reservoir protection. Through field application, the acidizing fluid system have obtained better result in improving measure efficiency and reducing the oil reservoir damage.
