摘要

Double packer equipment for hydraulic test can be used to measure pressure of testzone directly, and it is frequently used to perform many kinds of hydraulic tests and takegroundwater sample from borehole. The test method of this equipment mainly includes the testdesign, implementation, interpretation and synthetic analysis. By adopting the double packerequipment for hydraulic test, the parameter distribution of rock permeability along boreholecan be acquired, as well as the connectivity, water conductivity and water bearing capacity ofthe disclosed structure and the chemical characteristics of the deep groundwater. It is anecessary method for the research and evaluation of the complex hypotonicity terrace siteselection under geological conditions. This method is not only suitable for the geologicaldisposal of high level radioactive waste, but also can be used in the site selection ofunderground facilities such as storage of petroleum and carbon dioxide. Meanwhile, it has agood application prospect in other hydrogeological investigation fields.
