冬季呼伦湖环境科学钻探冰上湖泊钻探平台及取样技术

Icy Lake Drilling Platform and Sampling Technique of Environment Scientific Drilling in Hulun Lake in Winter

摘要:

针对内蒙古呼伦湖的气候特点，为保证工作安全，实施冬季冰上湖泊环境科学钻探，设计研制了冰上湖泊钻探平台系统，满足了工程施工要求。考虑到呼伦湖沉积地层特点，研制了新型活塞式取样钻具和压卡式取样钻具，实践证明，取样效果良好，取心率达到了100%。

Abstract:

According to the climate characteristics of Hulun Lake in Inner Mongolia, system of icy lake drilling platform was designed for assuring the work safety and implementing of scientific icy lake drilling in winter. Considering the strata characteristics of Hulun Lake, new piston sampling drilling tool and press-fitting sampling drilling tool were developed. The practice proved that the result of sampling is satisfying with the coring rate of 100%.
