天然气水合物泥浆制冷系统的野外试验研究

天然气水合物钻探取样过程中，泥浆制冷系统具有十分重要的作用。介绍了吉林大学研制的天然气水合物泥浆制冷系统的结构及工作原理。通过在西藏羌塘盆地、祁连山木里盆地和东北漠河盆地大兴安岭地区的野外应用试验，表明该套系统应用范围广，工作性能稳定可靠，可用于高海拔、高纬度的冻土带等特殊地区的水合物钻探。

Field Test Study on Gas Hydrate Mud Refrigeration System

Mud refrigeration system is very important in the drilling process of gas hydrate sampling.This article describes the structure and working principle of the gas hydrate mud refrigeration system developed by Jilin University.The field ap-plication tests were made in Qiangtang basin, Muli basin and Mohe basin, the test results show that the application scope of this refrigeration system is wide with stable and reliable performance, and can be used in gas hydrate drilling in high alti-tude and high latitude permafrost regions and some other special areas.
