摘　　要：针对宝浪油田注水井注水压力高、效果差的问题,在对自生酸的筛选基础上,进行岩屑溶蚀率试验,得到的自生酸体系具有腐蚀低、反应速度慢、深部解堵能力强的特点。岩心模拟试验评价表明,该自生酸体系可以使低渗透岩心的渗透率提高215.7%,并在宝浪油田3口井上进行实践应用,取得良好的应用效果。In consideration of the high-pressure and poor effect of the water injection well,in Baolang Oilfield,based on the screening of self-generating acid,a self-generating acid system was used for testing cuttings dissolved rate,the characteristics of low corrosion,slow reaction rate and strong deep plugging removal capability were obtained.Core simulation experiment shows that the self-generating acid system can make the permeability increase of low permeability cores for nearly 215.7%,and it is applied in 4 wells of Baolang Oilfield,good application effect is obtained.
