摘要
本文系统研究了紊流注水泥顶替机理的理论及数学模型,并对幂律流体及宾汉流体在偏心环空中的紊流流动及紊流顷铸,求出了数值解。研究了水泥浆及泥浆在隔离液中的紊动扩散规律,并导出了计算紊流注水泥最小隔离液体积及最小紊流接触时间的公式。
The displacement mechamcs theory and the mathematical models of turbulent flow for cernenting has been studied systematically,the numerical solutions have been obtained for the turbulent flow and displacement of power law fluid and Bingham fluid in eccentric annuli in this paper.The laws of the turbulence diffusion of cement slurry and mud in spacer have been investigated,and the formulas of calculating the minimum volume of spacer and the minimum turbulent contacting time for turbulent cementing have been made out.
