Practice of Drilling Construction for Gas Hydrate in a Basin in Northeast

Abstract:

Combustible ice land drilling is just starting in China, which is the same with core drilling in some ways and also has its own unique features. Through engineering case, the paper introduces the requirements of combustible ice land drilling technology and technical issues of derrick foundation construction in permafrost region, combustible ice sampling drilling and the preparation, maintenance and the use of low temperature mud. The development requirements of combustible ice drilling and sampling in the future are expounded.
