水文钻探冲洗液除具备一般钻进所需的冲洗功用，保证钻进顺利安全外，还要求其不破坏含水层构造，不影响对水层的评价。尤其是第三纪和第四纪地层，采用粘土造浆或清水钻进自然造浆很难达到上述要求。蒟蒻冲洗液则比较适用于水文钻探，能满足上述要求。一、蒟蒻冲洗液的特性蒟蒻冲洗液不但有一定的粘性，能在孔壁上形成泥皮，保证钻进顺利，而且能在一定的时间内失去其粘性，使泥皮自动破坏而不污染、堵塞含水层。图1和图2是在室温条件下，蒟蒻冲洗液粘度及失水量变
In addition to having the flushing function required for drilling in general and ensuring smooth and safe drilling, the hydrological drilling fluid also requires that it not destroy the aquifer and does not affect the evaluation of the water layer. Especially in the Tertiary and Quaternary formations, it is very difficult to achieve the above requirements by using clay slurrying or water drilling for natural slurrying.蒟 蒻 flushing fluid is more suitable for hydrological drilling, to meet the above requirements. First, the characteristics of 蒟 蒻 rinse solution 蒟 蒻 rinse fluid not only has a certain viscosity, can form mud on the hole wall to ensure smooth drilling, but also in a certain period of time to lose its viscosity, so that the mud does not automatically damage the pollution, Clogged aquifers. Figure 1 and Figure 2 is at room temperature, 蒟 蒻 rinse fluid viscosity and loss of water change
