摘要

对昆仑山前平原到塔克拉玛干沙漠腹地的地下水观测断面进行取样分析,利用Piper三线图及NETPATH水质演化模型,阐明了区域地下水化学特征,揭示了地下水化学演化机理,旨在为研究区地下水的可持续开发、水质保护与改善提供科学依据。结果表明:(1)研究区地下水化学类型为Na-Mg-Cl-SO4型和Na-Cl-SO4型;(2)强烈的蒸发浓缩作用,芒硝、岩盐、辉石的溶解作用,较为显著的Ca2+/Na+离子交换作用是研究区地下水化学组成的主要演化过程。

Abstract

The oil and natural gas resources are rich in the hinterland of the Taklamakan desert, where weather is extremely dry, ecological environment is extremely frail. In this study,in order to provide dependable foundation for the reasonable exploitation of groundwater, the protection and improvement of water quality. A section crossing the from Kunlun piedmont to the hinterland of Taklimakan Desert is monitored,Piper diagram is utilized to analyze the hydrochemical type, and NETPATH Modeling is used to simulate the process of chemical evolution of groundwater. The results obtained are stated as follows: (1) The groundwater hydrochemical types are comparatively single in the area, the main types are Na-Mg-Cl-SO4 and Na-Cl-SO4; (2) The main representation properties of the water chemical evolution model are the strong evaporation and concentration, the dissolution of mirabilite, rock salt and pyroxene, and the more prominent Ca2+/Na+ ion exchange.
