Streamline Simulation And Application Of Multiple Injection/production Pattern

In the past few decades,the streamline model has achieved rapid development.Due to the fast simulation speed,it is being used more and more in the simulation flow,the history fitting,the best well location choice and the component simulation.But the existing streamline model has many defects,such as most of the models are assumed to be two-dimensional geological,fluid and rock is incompressible,isotropic,heterogeneity,and thus the actual geology model has a great gap,the simulation results are not accurate,not representative.In order to solve these problems,this paper presents a new flow calculation model.The mathematical model considers the 3D geological shape,fluid and rock compressibility,heterogeneity,anisotropy,to make the geological model to minimize the assumptions and close to the actual phase.At last a 3D streamline method is given,and the changes of the flow line saturation are generated.Finally,in order to verify the practical application of the model,a three-dimensional flow field calculation program based on Web display is developed.Through the simulation of a variety of water flooding wells,the water flooding conditions of different well patterns and the effects of heterogeneous and high viscosity water injected on water flooding are predicted.
