Percolation Mechanics of Oil and Gas in Porous Media

via XuetangX

Overview

The course of "percolation  mechanics of oil and gas in porous media" is one of the main professional basic courses  to undergraduate students and postgraduate students in petroleum engineering , offshore oil and gas engineering , as well as engineering and technical personnel  in petroleum engineering field.

This course is to make students master the flow law of oil, gas and water in formation and the basic method of studying fluid seepage law through various teaching links. It is the preparation for students to choose reasonable mathematical model, study fluid movement law and make dynamic prediction according to stratum property, fluid property and geological condition after graduation. In order to solve practical problems in the process of oil and gas field development and engage in scientific research, necessary professional theoretical knowledge is prepared.

The main contents of the course include "basic law of seepage flow, stable seepage of single-phase incompressible liquid, interference theory of oil wells driven by rigid water pressure, unsteady seepage of slightly compressible fluid, seepage law of natural gas, theoretical basis of water drive oil and two-phase flow theory of oil and gas". The main line of teaching is to refine practical problems → analyze problems → reveal the essence → guide engineering practice.
