| Reflecting the underground water in the aquifer or filter movement and storage characteristics of hydro-geological parameters is to carry out various hydrological calculation of parameters of an indispensable. Analytic method are often used to calculat the hydrogeology parameters in practical work. Its advantage is analytical solution is a continuous functions, you can get precise head of every the space point and time point value. But for the dive well flow, dupuit formula for calculating parameters are often vary, so it is difficult to directly use. In order to better use analytical method for calculation of phreatic water aquifer of hydro-geological parameters, base on the present material and the research results by predecessors, this paper study on the analytical method of well flow formula for the basic principle and calculation of phreatic water aquifer advantages and disadvantages of hydro-geological parameters. The research results provided scientific base for practical work for the play. The results are summarized as following:(1) There are three groups of pumping test, two groups in the Refinery Plant while one group in dump zone, base on single pumping well with multi-observation well. The former last 149 hours, while the later 193.5 hours, and obtained water head,water temperature.(2) Analysis theroretical basis of Theis well flow formula and its assuming conditions. Under the premise of the generalizability hydrology geological condition, using fake Theis well flow formula for calculation of phreatic water aquifer of hydro-geological parameters. The results show as following:1) permeability coefficient of Refinery Plant K=6.132m/d and permeability coefficient of dump zone K=4.531m/d.2) Permeability coefficient of refinery factory with the increased water flow has increased, and permeability coefficient of dump zone with the increased water flow reduced.(3) Analysis theroretical basis of Bolton well flow formula and its assuming conditions. Research on the water-releasing principle of Bolton formula and using it should meet conditions of phreatic aquifer of hydrogeological. Using Bolton well flow formula for calculation of phreatic water aquifer of hydro-geological parameters. The results show as following:1) permeability coefficient, Coefficient of transmissibility, determination of specific and Lagging Index of Refinery Plant K=8.39m/d,T=258m2/d,μ=0.23,1/α=77; permeability coefficient Coefficient of transmissibility, determination of specific and Lagging Index of dump zone K=6.33m/d, T=315m2/d,μ=0.173,1/α=59.2) Lagging Index of Refinery Plant and dump zone is small.(4) Analysis theroretical basis of Newman well flow formula and its assuming conditions. Research on the water-releasing principle of Newman formula and using it should meet conditions of phreatic aquifer of hydrogeological. Using Newman well flow formula for calculation of phreatic water aquifer of hydro-geological parameters.1) permeability coefficient, Coefficient of transmissibility, and determination of specific of Refinery Plant K= 5.28m/d, T=199m2/d,μ=0.24; permeability coefficient Coefficient of transmissibility, and determination of specific of dump zone K=5.72m/d,T=238m2/d,μ=0.249.2)Lagging Index of Refinery Plant and dump zone is small.(5) By comparing the three well flow formula assumes that conditions in the research on the applicability and calculation of phreatic water aquifer focus of hydro-geological parameters of different come, Newman well flow model assumes condition and research of hydrogeological conditions of fitting the best, and using the well flow formula to calculate the results of the most close to the research experience. It has an advantage to calculation of hydro-geological parameters of phreatic water aquifer in testing area.
