多氢酸酸液体系的性能评价

Lab Properties Assessments for Multi-Hydrogen Acid

摘要: 多氢酸酸液体系是应用于砂岩油藏的一种新型酸液体系，它在国内的应用处于探索阶段。然而对于这种新型酸液的实验性能研究，尚未见国内有相关报道。在室内进行了多氢酸酸液体系的性能研究，实验包括多氢酸酸液体系与实际岩心溶蚀试验、多氢酸酸液体系与硅酸钠的溶蚀试验、多氢酸与碳酸钙反应氢离子浓度测定试验等。通过多氢酸酸液体系与常规酸液体系如土酸、氟硼酸等酸液的对比实验，探讨了多氢酸酸液体系的特性和实验规律；实验证明，多氢酸比常规酸液的性能优越。

Abstract: Multi-hydrogen acid (MH acid) is a new acid type for sandstone reservoir acidizing, however, the study on MH acid is quite immature and it is brand new in China. This paper concentrates on the properties of MH acid and experiments are conducted in lab par
