Drilling & Extraction of Gas Hydrate and Environment Protection

Abstract:

Gas hydrate is a new kind of super energy with great potential. Meanwhile it also is a factor of causing geological hazards. It can effect the changes of global weather. The technical measures, countermeasures and proposals deal with the drilling characteristic, drilling methods, mud system, coring, logging, well completion technology, extraction methods and so on, to prevent from geological hazards and environment contaminations, are put forward.
