Abstract
Domestic and overseas investigation showed that boundary element method was widely used in seepage flow, but it was mostly used in well bore pressure curve feature research of different reservoir types. Its use in unsteady production prediction has not been reported. Based on unsteady pressure dynamic problems research by boundary element method, the calculating method used to predict unsteady production by boundary element method is provided for the first time after adjusting the boundary integral equation. For checking prediction results, the homogeneous reservoir production with closed boundary or stable boundary was predicted, the small error with analytical solution showed that the production predicting method is accurate.
