前言泥浆鑽探的主要特点,就是不要套管,在供水水文地质勘察中采用这种方法,不仅解决了目前套管缺乏的问题,并且可以加快勘探速度,能鑽大口径鑽孔,下入较大口径的滤水管,既能提商勘探质量,又能结合生产。但是并不能认为在供水水文地质勘察中应用泥浆鑽探是轻而易举的事。由于孔内充满泥浆, Introduction The main feature of mud drilling is not casing, the use of this method in the water supply hydrogeological exploration, not only to solve the current lack of casing problems, and can speed up the exploration speed, can drill large diameter borehole into the larger Diameter of the drainage pipe, both to mention exploration quality, but also with production. However, it can not be assumed that the application of mud drilling in water supply hydrogeological surveys is a breeze. As the hole filled with mud,
