The Research of Capillary Pressure in the Process of CO Displacement in Low-Permeability Reservoir
View through CrossRef
The function of capillary pressure in the process of CO displacement in low-permeability reservoir is researched
through combination of indoor experiments and numerical simulation. On the basis of different displacement experiments
in long core chamber, one-dimensional numerical simulation component model is built to research the function
of capillary pressure under the different CO displacement ways. The results show that the capillary pressure under the
different CO displacement ways is not consistent. Capillary pressure is the driving force in the process of CO displacement
while resistance force in the process of CO pressure buildup and displacement. In order to promote reasonable and
efficient development of low-permeability reservoirs, it is suggested that further study about microscopic effects and laws
of the capillary pressure in the reservoir should be done through experiment.
