Abstract

Abstract:

A systematic study of percolation behaviors and deformation characteristics in low-permeability reservoirs with deformable medium is carried out through simulated test on core samples from Wendong area.The result suggests that pressure magnitude,pressurizing velocity and manner,and etc.,play important roles in percolation and deformation of reservoirs.The regular permeability is a variable relating to driving pressure difference and effective pressure.The initial pressure difference and its amplitude exert tremendous influence upon the reservoir deformation.Therefore the enhancement of oil recovery relies heavily upon a rational control of the initial pressure difference.

Key words: effective pressure, low-permeability, deformation media, core test, petrophysics
