The results show that: barium sulfate scale damage on the core permeability is affected by temperature, mixing ratio and the cumulative injection.

实验结果表明：硫酸钡结垢对岩心渗透率损害程度受温度、混配比例和累积注水量的影响。

The later includes well spacing, injection mode (gas injection or gas alternating water injection), solvent cumulative injection amount and the alternating frequency, etc.

工程因素包括井距、注入方式(注气或气水交替)、溶剂注入量、气水交替频率、射孔位置等。
