摘　　要：经过多轮次蒸汽吞吐开发,超稠油油藏水平井逐渐出现多重开发矛盾,如井间窜扰严重、水平段动用不均、油井存水率高等,单一驱油介质的辅助效果欠佳。为提升驱油介质的辅助效果,针对超稠油多介质协同提高采收率的技术作了深入研究。研究结果表明,在相同的驱替条件下,尿素+起泡剂的介质组合效果最佳,能起到较好的增能、调剖、降黏等驱油作用。通过油田现场应用,验证了多介质协同技术的有效性。After multiple rounds of steam huff and puff development,multiple development contradictions gradually appear in horizontal Wells of super heavy oil reservoirs,such as serious interference between Wells,uneven production of horizontal section,high water retention rate of Wells,and poor auxiliary effect of single oil displacement medium.In order to improve the auxiliary effect of oil displacement media,the technology of enhancing oil recovery through multi-medium synergy for super heavy oil was studied deeply.The results show that under the same displacement conditions,"urea+foaming agent"is the best combination of synergic oil displacement medium,which has better oil displacement effects such as energy enhancement,profile utilization and viscosity reduction.The effectiveness of multi-medium synergic technology is verified through its application in oilfield.
