Relations Theory Of Numerical Reservoir Simulation And Reservoir Engineering

To describe the formation fluid flow differential equations and their boundary conditions,and the establishment of a mathematical model of the reservoir flow pattern, the discretizationof the differential equation and its boundary conditions, the formation of higher order linearequations to discuss the value of the equationssolution. Reservoir numerical simulation inmany cases, and traditional reservoir engineering methods are consistent, while the purpose ofthis paper is to clarify the theoretical relationship between the numerical reservoir simulationand reservoir engineering methods.Comprehensive paper Summary reservoir numerical simulation methods, andapplications on a numerical reservoir simulation and its type, specific description of thenumerical reservoir simulation methods commonly used method for solving the numericalreservoir simulation in reservoir engineering. First discusses the reservoir material balancemethod in the study of the theoretical relationship of reservoir simulation and reservoirengineering methods, and numerical reservoir simulation method and the traditional massbalance method, generalized material balance method and solution gas drive reservoir Musketthe theoretical relationship of the method; discusses the analytical methods in reservoirengineering, reservoir numerical simulation and transient pressure analysis of the analyticalmethod, the dynamic analysis of the theoretical relationship Bucklet-Leveret method;discusses the reservoir decline curve method works to study the reservoir numericalsimulation and the Arps decline curve analysis methods, the theoretical relations ofproduction type curve method. The authors believe that the material balance method innumerical reservoir simulation and reservoir engineering, analytical method, the decline curvemethod is the same, interchangeable complementary applications.
