【Abstract】 It is found that the flowing to a well located at the center of low permeability reservior doesn’t obey Darcys law.A new mathematical model is set up,and solutions of Laplace space are presented.The behaviors of flowrate and cumulative flowrates are discussed.It is shown that the flowrate declines as quickly as Darcy flowrate at the beginning,and declines more quickly than Darcy flowrate at the end.The results obtained here can be used to analayze early time data in order to determine the properties of formation and to predict a well performance.更多还原
