摘要:The multi-component thermal method has the advantages of low thermal recovery temperature requirement, low heat loss, and high economic efficiency. In this paper, taking the B36 well of NB35-2 oilfield as an example, the influence of different injection factors of multi-heat fluid on the mining effect is explored. Based on the reservoir basic parameters, we carried out reservoir numerical simulation and systematically studied the influence of injection temperature, well time and injection volume on the periodical oil production. Finally, the injection parameters were optimized and the trend of viscosity field, temperature field and pressure field (downhole flow pressure) after injection was predicted. Multi-component thermal fluid stimulation can reduce the viscosity of formation crude oil and increase the productivity of oil wells, thus improving the development of offshore heavy oil reservoirs. This research has important reference value for improving oil and gas recovery.
