Abstract

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
