Abstract

In order to improve the sweep efficiency of water floods, many relative permeability modifiers (RPM) have been used to control water. RPM can modify the water/gas flows in the hydraulic fracture and reduce the water production. However, previous experiments were seldom focused on PRM effect of polymer for gas/water in shale gas reservoirs. During the experiment we use the ideal model, capillary tubes, to study the disproportionate permeability reduction mechanisms of polymer to gas and water in shales gas. From the research data, the disproportionate permeability reduction effect of polymer for gas/water flow are illustrated and confirmed by the results. Reduction of water permeability varies from 1.5 to 3.2 depending on different injection rates and is always larger than gas permeability reduction which remains close to 1. That shows the RPM may decrease the excess water production and increase the gas production in shales gas.
