摘要
利用流变学原理,概述偏心环空中的流变特性,讨论泥浆、水泥浆流性指数n、动切力对偏心环空注水泥顶替效率的影响。获得现场的验证。
Using rheology principle, the rheologic characteristices of the fluid in eccentric annulus is outlined and the influence of the rheologic index n and dynamic shearing force of the mud and cement slurry on displacement efficiency of cementing in eccentric annulus is discussed, which has been tested and verified by cementing practice.
