| Abstract: | On the basis of many results of construction ,this paper contrastively analyses the water-yield capacity of tube well drilled by clay-free drilling technology and by clay drilling technology, and indicates that the clay-free drilling technology is an important technical measure for increasing the water-yield.Especially in relatively water-poor districts of the Jianghuai region of Anhui province,this technology of clay-free drilling yields good results. |
