Application of Manufacturing Techniques of Slurry by Seawater , anti- salt bentonite from environmental geographical restrictions to get water, unaffected by severe weather, can be used at any time. It has a fast speed of dissolving, good hydration , high mud-making rate, very thin, strong stability, high ability of solid wall, low drill swing resistance, high drilling rate etc. Especially encountered sediment layers and salt in the construction, can prevent to collapse with strong inhibition ,also prevent to expand of the holes, reduce to meet resistance in the drilling process, be not to the end or sticking, etc.
