[Abstract]:Based on the actual reservoir model, this paper combines the percolation mechanism of composite reservoir and the similar structure theory of complex differential equation. In this paper, the solution of nonlinear radial flow mathematical model of composite reservoir under different external and inner boundary conditions is studied, and four kinds of complex reservoir models are established. A new method for solving the mathematical model of this kind of composite reservoir, the similar construction method, is obtained, and the concrete steps of this method are given. The flow chart of this method is as follows: firstly, algebraic transformation-variable substitution and Laplace transformation are performed on the established reservoir model, and then the construction theory of the solution of complex differential equation is used. The solutions of reservoir pressure and bottom hole pressure are obtained in Laplace space.
