[Abstract]:As the most effective means of groundwater monitoring, monitoring wells have been playing an important role in monitoring and studying the transformation between groundwater and surface water, analyzing the characteristics of groundwater hydrochemical changes and obtaining hydrogeological information of groundwater in the basin. On the basis of introducing the characteristics of multi-layer monitoring wells, this paper takes multi-layer monitoring wells as the research object, and focuses on the completion process of continuous multi-layer monitoring wells and the performance of watertight materials. The effectiveness test of multi-layer monitoring wells and the practical application of continuous multi-channel multi-layer monitoring wells in Heihe River Basin are studied and analyzed. The main conclusions are as follows: (1) compared with other multi-layer monitoring wells, The continuous multi-channel multi-layer monitoring well is more suitable for popularization and application in our country. It has the advantages of simple technology, low construction cost, low labor intensity of construction personnel, and the pipe material and sampling equipment have been made in China. It can better promote the development and application of continuous multi-channel and multi-layer monitoring wells in China. At the same time, automatic and intelligent monitoring is bound to be the direction of development of multi-layer monitoring wells in the future. (2) through geotechnical tests, The properties and applications of two new watertight materials (clay balls) are studied, which provide data support for the application of new watertight materials in multi-layer monitoring wells. (3) the completion process of continuous multi-channel multi-layer monitoring wells is improved and the operation efficiency is improved. The quality of well completion is guaranteed, and it is summarized as a set of systematic multi-layer monitoring well drilling and well completion technology. It provides a good reference for the popularization of this technique in groundwater monitoring work in China. (4) simple pumping test and salt conductivity test are used to test the watertight effect of adjacent watertight layers in multi-layer monitoring wells. It confirms the effect of multi-layer monitoring wells and proves the validity and accuracy of groundwater samples and other data information collected from multi-layer monitoring wells. It lays a foundation for the comprehensive popularization and application of groundwater multi-layer monitoring wells. (5) continuous multi-channel multi-layer monitoring wells can obtain a large amount of hydrogeological information, such as water level, salinity, ion concentration, etc. It provides technical support for monitoring and studying the transformation of groundwater and surface water and analyzing the hydrochemical characteristics of groundwater in Heihe River Basin. At the same time, through the practical application of continuous multi-channel and multi-layer monitoring wells in Heihe River Basin, combining the theory with field construction, the data accuracy and practicability of continuous multi-channel multi-layer monitoring wells are further proved.
