摘要
采用水文测井方法代替钻探取芯和分层抽水取样分析,可以较准确的确定含水层岩性、位置和矿化度,有利于降低成本。
The hydrologging work used in the non-core drilling is an advanced technical method.The opera- tion sequences include the classification of hole section,determination of aquifer depth and thickness and the semiquantitatve analysis for the degree of mineralization of aquifer.The practical application in the field shows that the coring by drill and layer pumping can be substituted by the hydrologging method to obtain a high rate of drilling,low production cost and low labour intensity and perfect eco- nomic benefit.It is more accurate and reliable to use the logging data for lithologic characters,depths of loose aquifers and their degrees of mineralization and the selection of available pumping sites in holes.
