经常用来表征钻井泥浆流变性的数学模式有宾汉模式和幂律模式,近年采用的还有卡森模式;凡流变性规律符合这些模式的液体,分别叫做宾汉液体、幂律液体和卡森液体。为了在泥浆循环系统的水力计算中,正确地选用有关的公式,澄清一些错误,现在将这三种液体的常用管流公式以表的形式列出。并且,为了对比起见,首先列出了牛顿 The mathematical models often used to characterize the rheology of drilling mud are Bingham and Power-Law models, and Carson’s model is used in recent years; where the law of rheology follows these modes of liquids called Bingham Liquids, Power Law Liquids and Cards Sen liquid. In order to clarify some mistakes in the hydraulic calculation of the mud circulation system, the relevant formulas are correctly selected and the common flow equations of the three liquids are now listed in tabular form. And, for the sake of comparison, Newton is first listed
