摘　　要：油基水泥浆是一种高效的选择性堵水材料 ,具有价格低廉、选择性好、作用有效期长和适用范围广等优点 ,在油井控水稳油作业中的应用日益受到重视 ,但是国内的研究与应用很少 ,对提高油基水泥浆油 /水置换效率的研究一直未有突破。通过优选表面活性剂 ,采用静置法考察了表面活性剂、温度和水样对置换效率的影响 。Oil based cement slurry is an effectively selective water plugging material whose applications are being highlighted in oil well water control and enhanced oil recovery for its low cost, high selectivity, long working life and wide range of application. But in China its research and application is just started and the improvement of transposing efficiency of the slurry is still a big problem yet to solve. Thus, the replacing efficiency of the slurries was studied by static displace method and selection of surfactants.It is a simple and useful guide for improving the performance of oil based cement slurry
