本文对定向井环室内幂律流体流动规律进行了理论分析和实验研究,建立了定向井环空流动物理模型,导出了幂律流体轴向定常层流流动的流场分布、流量和压耗模式,并对其变化规律分别作了详细分析。设计安装了定向井环空模拟实验架,对幂律流体在模拟环室内轴向层流流场和流动压耗进行了测量,并对流态变化规律、紊流压耗及内管旋转对幂律流体流动的影响作了探索性的试验研究。
In this paper, the law of power law fluid flow in directional well ring chamber is theoretically analyzed and experimentally studied. The physical model of annulus flow in directional well is established, and the flow field distribution, flow rate and pressure loss mode , And made a detailed analysis on the law of its change separately. Design and installation of a directional well annulus simulation experiment rack, the axial flow field of the power law fluid in the simulation chamber and the flow pressure loss were measured, and the change of flow pattern, turbulence pressure loss and the inner tube rotation of the power law The impact of fluid flow made an exploratory experimental study.
