In the actual production process of oil and gas reservoirs, the study of the redistribution characteristics of reservoir fluids is of great significance to the optimization of the indirect working system. Based on the nuclear magnetic resonance experiment, this paper analyzes the re-distribution of fluids in the core under the conditions of different shut-in times and different shut-in times. The distribution characteristics were studied. The results show that the water content increases with the increase of shut-in time and the number of shut-in times. For the same core, the water content in the large pores changes significantly.
