Abstract: Non-closed boundary are servoirs are very widesPread in reality.As for the percolation Problem of constant Pressure boundary and closed boundary，routine method can resolve it.But as for the Percolation Problem Of non-closed boundary，routine method did not work effeetively. the Boundary Element Methcd to study the non-closed boundary mathematical model Of well test inginterpretatlon was Presented in the PaPer，which was LaPlace
transform to the Percolation differential equation，the solution in the Laplace space with the Boundaly Element Methoel and then the SOlution in the real sPace with the Stehfest Numerical Method was worked out，which can be used to analyze the hole-bottom Pressure behavior.

Key words: homogeneous reservoir, arbitrary shape reser-voir, boundary element method, non-closed boundary, well testing interPretation
