摘要
天然气水合物是一种赋存于低温和高压条件下的新型清洁能源 ,被喻为潜在的常规能源的替代品。文章首先介绍了天然气水合物勘探现状 ,进而以维持天然气水合物相态平衡的分解抑制法为基础 ,介绍了维持水合物相态平衡的低温钻井液体系的应用情况 ,分析了钻井液在低温条件下的性能 ,提出在进行天然气水合物勘探的低温钻井液体系研究时 ,务必要注意对有机高分子聚合物和无机盐添加剂的选用 ,使钻井液体系具有良好的流变性能和稳定性。
Gas hydrate, a new kind of environment-friendly energy, which is now regarded as a potential alternative energy for regular energies, can stable exist at low temperature and high pressure. At first, the paper presents the current status of gas hydrate exploration. Then, based on the decomposition inhibiting method which keeps the phase state balance of hydrate, the low temperature drilling fluids to keep the phase state balance of hydrate is introduced. Also, the performance of the drilling fluids under low temperature conditions is analyzed. Some suggestions are proposed for low temperature drilling fluids used for gas hydrate exploration.
