Numerical Simulation of Low-Permeability Fractured Reservoirs on Imbibition

Abstract:

Low permeability fractured reservoir is a special reservoir with complex fracture distribution and dense matrix. Low permeability fractured reservoir always have small porosity, low pore pressure and permeability. Therefore, low permeability fractured reservoir has low oil recovery efficiency. Besides, the developing complex process and higher costs lead to lower economic benefit. Low permeability fractured reservoir production mechanisms in the fracture system mainly by the capillary force of water into the matrix. Therefore, the hydrophilic blocks of dense, self-priming effect of capillary water is the main mechanism of oil. In this study, numerical simulation, the establishment of a dual media model analysis showed that the capillary suction from the oil production rate and the final volume flow channel structure, the capillary force, viscosity of crude oil and other factors.
