| 摘 要： | 叙述了在牛35块Es3中低渗透砂岩油层酸化中实施综合油层保护技术及现场应用取得的效果。模拟酸化试验表明,该区储层岩心酸化效果很好,但现场实施酸化时却没有任何增产表现。在认清措施储层特征、地层油水特征基础上,采用常规稀土酸体系作为基本酸液配方,对油层保护酸液添加剂进行了优选,有效地防止了低渗透油田酸化过程中对油层的伤害,在牛庄低渗透油层现场酸化增产措施中取得了显著的增油效果

| Abstract: | This paper represents formation protection and its results in low permeable sandstone acid treatment of Niu 35 block. Simulated acid tests showed that acid treatment could effectively improve the core permeability in lab,but no effect in the filed aiding. Through analysis of formation and its fluid propensity,low permeable sandstone acidizing,employing thin mud acid systems and optimum selection of acid addictives,effectively prevented damage in low permeable sandstone acidizing and significantly improve the formation permeability of Niu 35 block. |
