摘　　要：油层内二氧化碳自生泡沫SPG驱油技术是三次采油技术一项新型体系,具有优越的流度控制和微观驱油特性,自生气体二氧化碳在油藏温度压力条件下,能够很好的溶解在油、水中,使原油膨胀降黏,自生泡沫体系结合了聚合物、泡沫及表面活性剂的多种优点,比单一泡沫体系及聚合物具有更大的优越性,起到了复合增效的作用,自生泡沫在羊一断块的成功应用,将会大幅度提高类似油藏的采收率,该技术具有现场施工简便易操作等特点。Inner reservoir self-generating carbon dioxide foam flooding SPG is one of new EOR technologies, with superior mobility control and microscopic oil displacement characteristics. Self-generating carbon dioxide gas at reservoir temperature and pressure conditions can be well dissolved in the oil, the water, which can reduce the crude oil viscosity. Self-generating foam system combines the advantages of polymer, foam and surfactant, which has more advantages than a single foam system or polymer and plays a role in complex synergistic. The successful application of self-generating foam flooding technology in Yang 1 fault block will greatly improve the recovery of similar reservoirs. The site construction technology is easy to operate.
