摘要
黑液是碱法造纸的工业废液，黑液中含有碱、碱木素和表面活性剂等多种化学成分。研究发现，黑液可用作部分油田驱油化学剂，黑液中添加聚合物、活性剂形成三元复合驱油剂，可明显提高驱油效率。
Black liquor is the waste liquor from paper mill by basic process.It consists of many chemical components,such as alkali,alkaline lignin and surfactant.It is found through research that black liquor can be used as part of oil displacement agent in oil field.Ternary combination flooding with black liquor,polymer and surfactant can improve oil recovery significantly.
