摘　　要：本文介绍了改进产品SDC-M型天然混合羧酸盐的主要性能特点,实验表明,在高温高盐条件下,SDC-M型天然混合羧酸盐与分散剂DSB复配使用,可较好地溶于不同矿化度的污水中,一定比例条件下,二者可与高二价阳离子形成超低界面张力,具有较好的洗油效果,可广泛用于油井洗井及单井吞吐采油技术中。The main performance characteristics of the improved SDC-M type of natural mixed carboxylate are introduced in this paper. Laboratory experiment showed that as the SDC-M is mixed with dispersant DSB at high temperature and high salinity, the compound can dissolve better in sewage with different salinity, and if the proportion of SDC-M with DSB is proper, the ultra-low interfacial tension among the two and high bivalent cation can be achieved, so the compound has better displacement efficiency and can be applied to production well washing and single-well 'huff and puff'.
