Abstract：The auto hydrogeological parameters monitoring and data processing system is developed to improve efficiency of hydrogeological tests，and the slug test is introduced instead of conventional hydrogeological test. It dramatically shortens the test period and decreases the working intensity under in-situ conditions with relatively low costs because pumping and observation wells are not required. The post processing system is developed，which deals with the data of steady flow pumping test，unsteady flow pumping test and slug test at the same time，and the test reports are offered timely. Through comparative application under in-situ conditions，it is proved that the system can satisfy engineering demand，which is a good substitute for conventional hydrogeological test.
