本文利用流体力学的基本原理,分析了幂律流体及牛顿流体环空轴向流层流流场的性质,得出了有关的计算公式,并通过室内试验进行了验证。文中还从理论上分析并指出了当前国内钻井界在分析环空流场性质时所使用方法的不完善处。
In this paper, based on the basic principles of fluid mechanics, the properties of the flow field of the axial flow laminar flow through the power-law fluid and Newtonian fluid are analyzed. The relevant formulas are obtained and validated by laboratory tests. The paper also analyzes and points out the imperfection of the methods used in the current domestic drilling circle when analyzing the properties of annulus flow field.
