CMT技术在地下水多层监测中的应用研究

Study on the Application of Continuous Multi-channel Monitoring Technique to Groundwater Multi-layer Monitoring

摘要:

随着地下水监测技术的不断完善和发展，单孔多层监测井技术广泛应用于地下水监测工作。CMT监测井就是其中的一种，该技术采用了新型成井结构方式，能够实现单井监测多层地下水，分层采集水样进行水质分析，有一井替代多井监测的特点，能够降低建井及监测成本，提高监测效率。利用CMT多层监测技术，在黑河中游进行地下水多层监测，根据实际监测数据进行水文地质分析，验证了CMT技术在地下水多层监测中的实用性和有效性。

Abstract:

With the continuous improvement and development of groundwater monitoring technology, the techniques, which use single-hole to monitor multi-level, supply in groundwater monitoring aspect widely. As a member of multi-level monitoring techniques, the continuous multi-channel monitoring well uses a new structure type of well completion to achieve monitoring multi-layer groundwater in single well, and collecting water samples for analysis of water quality. It can reduce the cost of construction and monitoring, improve monitoring efficiency. The issue described the completion materials and the improved well completion technology of continuous multi-channel monitoring technique in detail. Combining with application of the technique in Hei River basin groundwater monitoring processes and hydro-geological analysis of the actual monitoring data can verify the practicability and validity of continuous multi-channel monitoring technique.
