Abstract:In this article, the testing data
of the coring wells
was analyzed
to statistically summarize the variable regularity of reservoir physical
parameters after polymer flooding. The laser confocal method was used
to study the microscopic remaining oil distribution regularity in
natural cores, and the effects of different pore structures and permeability
levels on the remaining oil distribution were quantified. Both natural
and artificial cores were used to compare and analyze the differences
in displacement effic… Show more
