So, in order to solve this puzzle, some experimental EOR researches of new surfactants, including SL-1 (Amino-acid type) and SL-2 (Lycine type), for flooding have been done in the lab with low permeability artificial cores.

• 为此,针对提高低渗透油层采收率困难的问题,在室内进行了人造低渗透岩心新型表面活性剂(SL-氨基酸型和 SL-甜菜碱型,以下简称 SL-1和 SL-2)驱油提高采收率实验探索性研究。
