Among the petroleum reserve which has been launched into development in China, most of land oil fields in the East are at high water cut period, so the effect of oil extraction with Water Injection apparently become worse. The technique tertiary oil recovery has become the leading measure to promise continuous and stable production. Surface active agent used for oil displacement used in tertiary oil recovery can greatly improve recovery ratio of crude oil. The surface active agent used for tertiary oil recovery researched and developed by our company is a kind of new surface active agent. Different from the anionic surface active agent and the non- ion surface active agent which are commonly and widely used now, our product has overcome the disadvantage of easy absorption of anionic surface active agent and the weak stability of non- ionic surface active agent. It is a kind of efficient active agent used for oil extraction.
