摘　　要：本文介绍了甘油聚醚型注汽前预处理剂的组成及机理 ,室内实验研究和现场应用情况。该剂在锦州采油厂不同稠油区块现场试验 12口井 。GYG is a glycerine initiated EO/PO polyether. It can effectively decrease the interfacial tension between crude oil and water, weaken the tendency to emulsion creation and break down the emulsion formed in reservoir formations at high temperatures of injected steam. It functions well at ≤280℃ and is extremally thermally resistant up to 300℃. The reservoir formations in steam huff puff wells are treated by 0.5—1.0% aqueous GYG solution before a steam injection cycle. The field tests of GYG in 12 wells at west Huanxilin Oil fields, Liaohe, are all successful and result in increasing oil production and oil to steam ratio and in prolonging production cycle.
