井下降粘开采稠油技术研究
RECOVERY HEAVY OIL BY IN-SITU REDUCING VISCOSITY
-
摘要: 通过实验，研究了稠油的水热裂解反应。在此基础上，研制出了适合辽河稠油水热裂解的催化剂体系。在室内研究的基础上，首次在辽河油田曙光采油厂进行了4口井的现场实验，处理后稠油粘度下降80％以上，为我国稠油油田的开发提供了一种有效的方法。Abstract: The in-situ aquathermalysis of heavy oil in the field is studied in detail.Some new catalysts for heavy oil are developed.The results of laboratory test and fields tests show that after being treated with the catalysts,the viscosity of heavy oil reduced 8
