Particle migration and blockage in geothermal reservoirs during water reinjection: Laboratory experiment and reaction kinetic model

Abstract

Abstract During water reinjection in geothermal reservoirs, the risk of particle migration and blockage is often unavoidable, especially in the reservoirs with high mud content and poor consolidation. In this paper, a series of core flooding experiments using a sand-packed tube were conducted to evaluate the effects of water flow rate, sand grain composition, temperature, and confining pressure on the particle migration and blockage in reservoir. A novel reaction kinetic model was established to describe the process of particle migration and blockage in porous media. The results show that the movable particles in reservoir can be divided into fine particles (size
