摘要
本文研究了胀流型水泥浆在偏心环空中的速度分布、视粘度及流动状态的转变等问题。并以此为基础,探讨了胀流型水泥浆对固井顶替效率的影响。所得结论表明:胀流型水泥浆有利于提高泥浆的顶替效率。
The velocity profile, apparent viscosity and laminar - turbulent
transition for dilatant cement slurry flow through ecentric annuli are
studied in this paper. According to these, the effect of dilatant
cement slurry on mud displacement efficiency is explored. The
analytical results show that the use of cement slurries having dilatant
rheology is more favorable for mud displacement efficiency.
