密度差对水平段固井顶替界面影响规律研究

Study on the Influence of Density contrast on Cementing Displacement Interface in Horizontal Section

针对密度差对水平段固井顶替界面影响规律问题,首先从水平段环空流场计算网格模型以及水平段环空固井顶替流体力学模型两个角度出发,开展数值实验模型分析,对数值实验与结果进行研究,为了解密度差对水平段固井顶替界面的影响规律奠定基础。

In view of the influence of Density contrast on the cementing displacement interface in the horizontal section,this studyfirst carried out numerical experimental model analysis from the two perspectives of the horizontal section annulus flow field calculation grid model and the horizontal section annulus cementing displacement Fluid mechanics model,and studied the numerical experiments and results to lay the foundation for understanding the influence of Density contrast on the cementing displacement interface in the horizontal section.
