钻井液用页岩抑制剂研究进展

Research progress of shale inhibition for drilling fluid

钻井液处理剂中的页岩抑制剂是通过化学方法合成得到的,将其添加到钻井液体系后,从反排上来的岩石样本能够直接反馈页岩抑制剂与黏土矿物的作用行为,如何理解它的行为和它在钻井液体系中的作用原理对我们是一种挑战,因为不同形式的页岩抑制剂在体系中会发生复杂的化学和物理反应。本文综述的内容能够帮助理解页岩抑制剂的行为,该类处理剂能够有效地提高黏土抑制效果。

Many of the chemical inhibitor additives have been developed through systematic methods with the use of standard clay-rich rock samples.These rock samples have relatively simple geologic characteristics and predictable behaviors.Understanding the behavior and re- sponses of shale to shale inhibitor additives of drilling and completion fluids has been a challenge for many years because of the numerous and complex chemical and physical vari- ations present in these type of formations.This paper reviewed that to show hoe the integra- tion of the geological aspects can help to understand the different responses of the shale to fluids and improve the selection of chemical additives for clay inhibition.
