Abstract：A rapid field test system(HSZK–01) is developed to determine the permeable parameters of rock and soil masses based on the oscillating principle of fluid movement inside a single well，which makes it possible to obtain hydrogeological parameters quickly. The functions，frames and field operating procedures of the test system are introduced. Based on the Visual Basic language，a processing program is compiled to manipulate data obtained by variable frequency instrument(HGW–01)；and the relative coefficients are acquired automatically. High-grade parameters can be determined in a short time. Furthermore，the effect of this test system on groundwater and its surrounding environment is free while working. Both slug test and pumping test are conducted in the same well；and the test data are analyzed using various methods to obtain the permeable parameters. The results are in the same order of magnitude and show a good fitness，which verify the reliability of the test system and the accuracy of the theory.
