| 摘 要： | 目前在井场对泥浆循环系统的压力损耗尚难得到简单而精确的实用计算,主要有以下一些原因:1.各种计算方法所根据的“模式方程”并不符合泥浆实际的流变特性。2.井下不同深度温度与压力的变化,随时改变泥浆的流变性。单纯地根据在地面上所测得的数据不能体现出这种变化。

| Abstract: | A new model equation of hyperbolic type with three parameters is proposed to express the rheological characteristics of yield-pseudoplastie fluids. Based on such a model, calculating formulas to evaluate the pressure losses of moving fluids inside circular pipes as well as annuli for both laminar and turbulent patterns, have been derived. They are both simple and accurate enongh to be utilized in practices as compared with other formulas commonly used. |
