摘要：
本文利用流体力学中的紊动扩散基本方程式,研究了油井注水泥作业中,水泥浆与泥浆在隔离液中的紊动扩散模式,并求出了水泥浆与泥浆在隔离液中的紊动扩散规律。最后利用这-扩散规律,导出了注水泥最小隔离液体积计算公式及紊流接触时间计算公式。这些公式可以作为现场油井注水泥隔离液设计的参考。
关键词: 注水泥 隔离液 扩散
Abstract:
Using the hydromechanics basic equations of turbulence diffusion, this paper studies the models of the turbulence diffusions of the cement slurry and the mud in the spacer in oil well cementing, and derives the laws of the turbulence diffusion of the cement slurry and the mud in the spacer, as a result, presents the formulas of calculating the minimum volume of the spacer and the turbulent contacting time in well cementing, These formulas can be used for spacer design in well cementing in oil fields.
Key words: Cementing, Spacer, Turbulence, Diffusion
