Experimental method for deep underground water formation evolution research in bedrock fracture area

Abstract

The invention belongs to the technical field of hydrogeology, and particularly discloses an experimental method suitable for deep underground water formation evolution research in a bedrock fracture area, which comprises the following steps of 1, coring and drilling a research area in the bedrock fracture area, and collecting deep undisturbed underground water, 2, carrying out indoor water-rock interaction experiments at different temperatures on the deep undisturbed underground water collected in the step 1 and the rock core sample at the corresponding depth, and 3, collecting a water sampleafter the water-rock interaction reaction in the step 2, sending the sample for testing, and analyzing the formation and evolution process of the deep underground water in the bedrock fracture area according to a test result, so as to complete the research on the formation and evolution process of the deep underground water in the bedrock fracture area. The method provided by the invention can provide a quantitative basis for research on formation and evolution of deep underground water in the bedrock fracture area by carrying out indoor deep water-rock action experiments at different temperatures.

Description

technical field [0001] The invention belongs to the technical field of hydrogeology, and in particular relates to an experimental method suitable for studying the formation and evolution of deep groundwater in bedrock fissure areas. Background technique [0002] Bedrock fissure water is mainly distributed in mountains and high hills, the lithology of the aquifer is mainly granite, and the groundwater mainly occurs in the fractured zone where joints and fissures are developed. Bedrock fissure water is a valuable groundwater resource, but it poses a threat to the construction of large-scale underground projects, especially those with large depths. And revealing the formation and evolution process of deep groundwater in bedrock fissure areas is the key to its exploration, evaluation and rational development and utilization. However, due to the heterogeneity and anisotropy of bedrock fissure water, it is very difficult to study the formation and evolution process of deep ground...
