讨论了在天然气水合物地层中钻进时正常钻进与井内温度的关系,指出了冲洗液在其中的作用,论述了井内温度规程与冲洗液冰点、冲洗液初始温度、冲洗液循环时间、冲洗液类型和性能的关系,并提出了相应的建议。 The relationship between the normal drilling and the temperature inside the well during drilling in gas hydrate stratum is discussed. The role of rinsing fluid in the well is pointed out. The temperature regulation in the well, the freezing point of the rinsing fluid, the initial temperature of the rinsing fluid, the rinsing fluid circulation time, Liquid type and performance of the relationship, and put forward the corresponding recommendations.
