Abstract



The efficiency of conventional thermal recovery methods is limited due to heat loss, steam overlapping and other serious problems. Steam injection assisted by various additives, such as no-condensable gas, solvent and surfactant, has proved to be an effective and beneficial method to improve thermal oil recovery. However, based on literature review, few systematic and comprehensive explanation of the mechanism of the compound system of gas-chemical agent and the application criteria.


In this paper, 3D physical experiments with different types of wells and heavy oil were conducted. The additives consist of nitrogen and viscosity reducer (VR). Different injection fluid combinations (single gas, single VR and gas-VR co-injection), fluid injection configurations (gas-steam and gas+steam, VR-steam and VR+steam,) were designed to study the effects of the compound system on oil recovery, oil-steam ratio and oil production rate.


The results indicated that steam injection assisted by gas-VR performs well in enhancing the thermal recovery. Some conclusions are drawn according to the variation curves of characteristic parameters. The effects of the compound system still worked and increased the oil recovery after different injection patterns. Meanwhile, the cumulative SOR decreased to the different extent after the corresponding processes sequentially. The distribution of temperature showed that gas-VR co-injection not only inhibited steam overlapping, which promoted the horizontal expansion of the steam chamber but also reduced the viscosity of heavy oil significantly. More oil was produced due to the gas expansion energy. In summary, this work provides a practical understanding of CSS assisted by gas-VR co-injection and optimizing of the injection schemes for different types of reservoirs.
