高原冻土水合物钻探冲洗液的研究

分析了国外冻土和冰层取心钻探冲洗液应用技术现状,从冲洗液抗低温能力,防冻剂和抗低温处理剂的选择,以及泥浆的抑制性、降失水性等方面对高原冻土水合物钻探冲洗液的研究和野外应用提出了建议。

Study on Drilling Fluid for Hydrate in Plateau Permafrost

Analysis was made on present situation of application technique of drilling fluid for coring in frozen soil and ice sheet in foreign countries, and suggestions were made on study of drilling fluid for hydrate in plateau permafrost and field application, such as selection of resistance ability of washing fluid to low temperature, antifreeze agent and anti-low-temperature treatment agent; inhibit and fluid loss reduce of drilling mud.
