本文从分析固井施工入手,运用流变学理论,提出在不同阶段选用不同的环空流态,来计算水泥浆的上返速度,确定合理的注替排量。并对今后固井施工和设计提出了改进意见。
Based on the analysis of cementing construction and using the theory of rheology, this paper proposes that different annulus flow regimes be selected at different stages to calculate the upward velocity of cement slurry and determine the reasonable displacement displacement. And put forward suggestions for future cementing construction and design.
