摘　　要：火驱是稠油油藏一次和二次开发的有效手段,火驱比水驱过程更复杂,利用油藏工程方法研究火驱油藏的开采动态的方法更少。提出了利用气驱特征曲线研究火驱稠油油藏开发动态的新方法,较好地解决火驱稠油油藏开发过程中的动态分析问题。经克拉玛依油田红浅1井区和罗马尼亚Suplacu等油藏的生产动态数据验证,根据此气驱特征曲线可建立累计产油量与累计产气量、生产气油比的关系式。在火驱达到经济极限条件时,依据此关系式可确定火驱可采储量。Fire-flooding or in-situ combustion is an effective process for primary and secondary development of heavy oil reservoirs.Com-pared with water drive,this process is more complex,and few engineering methods can be used for studying production performance in fire-flooding reservoirs.The paper proposes a new method to study fire-flooding reservoir＇s productoin performance with gas-drive type curves,by which the problems in dynamic analysis during production can be well solved.This new method has been proved by production perfor-mance data obtained from Wellblock Hongqian-1 in Karamay oilfield and Suplacu oilfield in Rumania.Relations among cumulative oil pro-duction,cumulative gas production and produced GOR can be established on the basis of the gas-drive type curve.Finally,recoverable re-serves by fire-flooding process can be determined with the relations as the fire-flooding reaches the economic limits.
