摘　　要：文章介绍了冲洗液的几种常见流变模式,并对这几种流变模式的流变曲线及其特点作了简单分析总结。通过多次室内试验测得SM植物胶冲洗液的各项流变参数,并根据这些参数作出它的流变曲线,通过与传统流变曲线作对比总结出SM植物胶冲洗液的流变方程表达模式为幂律模式;结合实践中常见的一些现象并通过两组不同的特征试验证明SM植物胶冲洗液为粘弹性流体而非传统观念上的假塑性流体;与传统泥浆对比试验证明SM植物胶冲洗液的流变性能优越;文章结尾对SM植物胶冲洗液的流变参数作了简单的分析讨论。This paper presents several common rheological models of drilling fluids and analyzes features and the consistency curves of these models.Through many experiments in laboratory,we obtain rheological parameters of SM vegetable gum drilling fluid.And the consistency curve of SM vegetable gum drilling fluid is drawn up based on these parameters.It is concluded that its rheology equation is power law model through comparing with common rheological models.Based on two different characteristic experiments,this study shows that SM vegetable gum drilling fluid is a viscoelastic fluid rather than pseudo-plastic fluid suggested in the past.Comparison with traditional slush indicates that the rheological properties of this fluid are better than mud.Finally this paper discusses reheological parameters of the SM vegetable gum drilling fluid.
