(I) The Objectives and Tasks
This course is a basic course of the major, whose task is to help students to grasp basic concepts, theories, calculations and experimental skills, with the purpose of laying solid foundation for undergraduates. The students are required to learn the physical properties of reservoir rocks, reservoir fluids, determination method and engineering application. The students are also required to understand and grasp the interfacial phenomena, the seepage mechanism in porous media and their applications in petroleum engineering.
(II) Basic Requirements
1、Grasp the basic concepts of the physical parameters of oil, gas and water, their determination method and empirical formula. Grasp the physical properties of the fluids and the law of phase change (composition, phase state, phase equilibrium, phase properties at high pressure)
2、Grasp the phase properties of the reservoir rock (porosity, permeability, saturation, specific surface etc.) and their factors.
3、Understand the interfacial phenomena, capillary pressure, multiphase distributionin the porous media. Grasp the mechanism of the multiphase flow of oil, gas and water (including wettability,capillary pressure, relative permeability, etc.). Explain the basic phenomena in reservoir engineering.
4、Use the physical parameters for the calculations in respect of reservoir engineering.
