摘　　要：克拉玛依油田红浅1井区将火驱作为稠油油藏注蒸汽(蒸汽吞吐、蒸汽驱)后的一种接替开发方式,进一步提高原油采收率。通过油藏数值模拟、物理模拟等方法,研究了该种方式下次生水体对火驱进程的影响,并给出了火驱开发过程中一线生产井的5个生产阶段及各阶段生产特征。结合矿场试验实际生产动态,分析了生产井见效初期的3种产状及不同产状的形成机理。这对分析类似油藏的火驱动态具有重要意义。As a succeeding development process following steam injection（huff and puff,steam drive） in heavy oil reservoir,in-situ combustion has been used in WellBlock HQ-1 of Karamay oil field in order to further enhance oil recovery.This paper studies the effect of ground secondary water on in-situ combustion process,presents five production stages and their production performances of producers by means of reservoir numerical simulation and physical modeling methods,and analyzes the three different occurrences and their formation mechanisms in early responses.These will be of significance of grasping the fire-flooding performance under similar reservoir conditions.
