Laboratory Evaluation of the Plugging Performance of an Inorganic Profile Control Agent for Thermal Oil Recovery

During the process of steam thermal recovery heavy oil, channeling seriously affects production and ultimate recovery. In this study, fly ash was used as plugging agent, then a series experiments based on results two-dimensional (2D) were conducted to study effect breakthrough channels. The experimental show that inorganic particle agent made from had good suspension stability, consolidation strength, injection performance. Because these characteristics, it migrated farther in formation with high permeability than low permeability, rate greater 99%. After injection, anti-flush ability stable performance formation. terms oil displacement effect, effectively improved because plugging. could control development reservoir.
