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

摘要:

我国可燃冰陆地钻探刚刚起步，它有别于岩心钻探，有自己独特的地方，也有相同的地方。通过工程实例介绍了可燃冰陆地钻探钻孔技术要求，冻土地区塔基制作，可燃冰钻探取样，低温泥浆的配制、维护和使用等技术问题，并阐述了可燃冰钻探取样今后的发展要求。

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.
