泥浆护壁技术在盐渍土和粗粒土层钻孔施工中的应用现状及展望
Application status and prospect of drilling fluid wall protection technology in drilling construction of saline soil and coarse-grained soil layer
摘要
Abstract
Drilling fluid wall protection technology is one of the key technologies to ensure the stability of borehole wall and anti-sloughing in drilling engineering.In drilling operations of saline soils and coarse-grained soils,there are significant challenges in traditional drilling fluid wall protection technologies.Drilling fluid is easy to be failure and instable due to the high salt content and expansiveness of saline soils,and rapid mud loss and poor support for the borehole walls due to the high permeability and low adhesiveness of coarse-grained soils.In this paper,the current status of drilling fluid wall protection technology for saline and coarse-grained soils are reviewed,the main challenges faced by these technologies are analyzed,especially the selection of drilling fluid types and the formulation,the development of new drilling fluid materials,and solutions for enhancing drilling fluid stability and wall protection performance in various soils.Moreover,the recent advances in the development of high-salt-tolerant drilling fluid,compound drilling fluid,and eco-friendly drilling fluid are also emphasized,and the future direction of the material develepment is posed,which provides a reference for the optimal application of drilling fluid wall protection technology in special soil layers.关键词
