本文针对这一问题,提出了一种基于密度的钻井液设计方法,通过实验测定不同密度的钻井液在钻井过程中的性能,并结合地层特点,确定了适宜的钻井液密度范围
同时,本文探讨了钻井液密度在井下操作中的控制方法和应用效果
关键词:钻井液;密度;盐膏层;井壁稳定;地层损伤AbstractThe salt layer in the Weicheng structure of the Zhongyuan Oilfield is an important natural gas reservoir, and drilling fluid is needed to control wellbore stability and reduce formation damage during drilling
In response to this issue, this paper proposes a density-based drilling fluid design method, which determines the performance of drilling fluid with different densities during the drilling process through experiments, and determines the suitable range of drilling fluid density based on geological characteristics
At the same time, this paper discusses the con
