In order to achieve efficient and reasonable development in the situation of horizontal well's widely application in oil and gas reservoirs, further research of horizontal well should be conducted. Researches about horizontal well mainly aimed at productivity while fewer on the development dynamic. The linear horizontal-vertical well pattern model is built, combined with two-phase flow theory the...
In this paper, Poly flow software is used to calculate the isothermal flow of three model fluids in contraction channel. The streamline contours, the speed contours and the pressure contours are drawn. Great efforts were put into further study of flow properties. As Weissenberg number (We)increasing, the vortex exists in the corner of contraction becomes bigger, the velocity contour is closer to the...
In many applications, streamline simulation shows particular advantages over finite-difference simulation. By the advantages of streamline simulation such as its ability to display paths of fluid flow and acceleration factor in simulation, the description of flooding process gets more visibility. The communication between wells and flooding area has been represented appropriately. In low permeability...
According to the behavior that the polymer solution has the characteristics of viscosity and elasticity, the transient flow mathematical model has been established and has been solved by using finite-difference method. The type curves have been plotted. The influence of some properties of polymer solution on the characteristics of the type curve has been analyzed. Compared with the curves simply considering...

In order to visually reflect the characteristics of pressure distribution and flowing tracks of reservoir fluid in anisotropic reservoirs, By means of the source-sink theory, Newman's product method and potential superposition principle, the transient flow pressure distribution equation of horizontal well pattern is obtained, the calculation method of seepage field streamline is presented, and the...
The mathematical model of transient flow considering threshold pressure gradient in vertically fractured multi-well system of reservoir with arbitrary shape is developed and solved by using finite element method. And the behavior of the bottomhole pressure varying with time is obtained. Then wellbore storage coefficient and skin factor are introduced by means of Laplace Transformation and Stethfest...
In this article, a finite volume method for the numerical solution of viscoelastic flows is presented. The flow of Phan-Thien-Tanner (PTT) model fluid through a contraction channel has been chosen as a prototype example. The conservation and constitutive equations are solved using the finite volume method (FVM) in a staggered grid with an upwind scheme for the viscoelastic stresses and a hybrid scheme...
