Experimental Research on Characteristic of Particles Transportation in Low-permeability Gas Reservoirs

摘要：

Characteristics and reasons of particles migration in low-permeability gas reservoirs are studied in this paper based on indoor experiments. In order to control the migration of clays, applying effect of two clays stabilizing agents compared and analyzed. The results show that particles transportation and blockage is a serious damage fact of which producing pressure differential is the main reason in low-permeability gas reservoirs. Stabilizing agents can effectively control the expansion and diffusion of clays, but the effect on fine silt is limited.
