The upper flow of drilling fluids in the boreholes is an eccentric laminar helical one, not an axial flow, when wells, especially directional and horizontal wells, are being drilled. The study on the laminar helical flow of drilling fluids in eccentric annuli is just at its beginning in the world. Based on the principle of fluid mechanics, the law of laminar helical flow of power-law fluid in eccentric annuli is thoroughly studied in this paper.

The upper flow of drilling fluids in the boreholes is an eccentric laminar helical one, not an axial flow, when wells, especially directional and horizontal wells, are being drilled. The study on the laminar helical flow of drilling fluids in eccentric annuli is just at its beginning in the world. Based on the principle of fluid mechanics, the law of laminar helical flow of power-law fluid in eccentric annuli is thoroughly studied in this paper. The apparent viscosity, velocities, calculating methods of flow rate and pressure loss of laminar helical flow of Power-law fluid are presented. On the basis of theoretical studies some new results of present paper are compared with the theories of the helical flow in concetric annuli and tests of liquid/ solid flow. The tests show that the theoretical formulae can be applied to for calculation in drilling engineering.

在石油钻井工程中,特别是在定向井、水平井正常钻进时,井眼中的上返钻井液液流属于偏心环空层流螺旋流,而不是轴向流。作者依据流体力学原理,研究了幂津流体在偏心环空中的层流螺旋流流动规律,探讨了视粘度分市,速度分布及计算流量和压降的方法。文中还将部分结果与同心环空流理论及两相流实验值作了对比。经过验证表明:文中新的理论公式可用于钻井水力参数计算。

A quasi 3D model consisting of depth averaged 2 D model, based on a two fluid model of turbulent liquid solid flows, is proposed to simulate sedimentation in estuary. Comparison of predictions with experiments shows that the proposed quasi 3D model is better than the depth averaged 2 D model in predicting sediment flows.

本文从湍流两相流动基本理论出发,建立了挟沙水流的湍流液固两相流动的时均方程组和封闭模型.结合实际工程建立了定常悬沙淤积的二维水深平均的全场模型以及准三维模型.数值预报与潮汐水流物模试验比较表明:二维水深平均的全场模型模拟所得回流区内旋涡外缘的悬沙淤积量大于涡心处的悬沙淤积量,这一数值预报结果与物模试验结果不符,说明二维水深平均全场模型不适宜于预报悬沙淤积;准三维模型模拟所得回流区涡心处的悬沙淤积量大于旋涡外缘处悬沙淤积量而且回流区中的悬沙淤积厚度的数值预报结果与物模试验结果比较接近,这说明准三维模型用来预报回流区的悬沙淤积是可行的.
