深共晶溶剂抑制页岩水化的应用与展望
Application and Prospect of Deep Eutectic Solvent Inhibition in Shale Hydration
摘要
Abstract
Shale hydration during drilling often leads to serious downhole safety accidents,and improving the stability of shale borehole will greatly improve the success rate of drilling.As a new type of green reagent,deep eutectic solvent(DES)has similar properties to ionic liquids and is widely used.However,its potential as a water-based drilling fluid additive in inhibiting shale hydration has not attracted enough attention.Compared with other water-based drilling fluid additives,DES has the advantages of non-flammable,non-explosive,non-toxic,easy degradation,good electrochemical and thermal stability,and DES is cheap and comes from a wide range of sources.In this paper,on the basis of comprehensively summarizing the physical and chemical properties of DES,the mechanism of DES as a water-based drilling fluid additive to inhibit shale hydration is discussed,and the application potential of DES to inhibit shale hydration is clarified by analyzing the cost,the influence of DES on the performance of drilling fluid,and the application of DES.The results of this study are of great significance for the application and promotion of DES in inhibiting shale hydration.关键词
