| Abstract:Since the existence environment and the characteristic of the gas hydrate are special, the most effective way to really get to know the physics and chemical natures of gas hydrate is to depend on the drilling sampling. Drilling equipment, drilling tool, drilling technologies and special drilling fluid are the most important factors to meet the requirement of the drilling and sampling engineering. The structures and principles, features, drilling technology and trial result of the sampling drilling tools for gas hydrate are introduced in the paper. And also, according to the characteristic of ocean drilling, the practical and economical drilling program for gas hydrates drilling in China is presented. |
