| Abstract: | In this paper,a new mathematical model of finite conductivity vertical fracture was built.Not only considering the deformed medium but also the effects of the quadratic-gradient term and the borehole storage.The numerical solutions of the new models were obtained by Newton-Raphson method in an infinitely large system.The new theoretic were formed and the sensitivity of the influencing parameters of the models was studied by using these curves,and the results can be applied to well-test analysis. |
