| Abstract: | Aiming at the problem that the nonlinear flow law is not deeply studied in low permeability reservoir,a new nonlinear flow model is derived based on mechanical theory according to the capillary model and boundary layer theory,which seeks out the mechanical reasons causing the present of nonlinear flow.The objective existence of nonlinear flow is verified in terms of the laboratory test result of 16 cores,and at the same time the accuracy and reasonableness of the new model are also verified.The nonlinear flow simulation software was also developed.The result of numerical simulation shows that even if the threshlod pressure gradient sections with different nonlinear sections are completely same,the predicated production quotas are perfectly different,which indicates the essentiality of considering nonlinear flow from numerical simulation study. |
