| Abstract: | Through the study of well testing model of anisotropic partial penetration vertical fractured well,we can obtain the parameters needed in inflow performance analysis and numercial simulation.On the basis of predecessors’ achievements,the transient pressure expression of partial penetration fractured well is obtained by Newman product principle methods.Using the Stefest numerical invention,solutions and the pressure and pressure derivative curves are obtained with the considertion of wellbore storage and skin factor,and the seepage periods are also analyzed. |
