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。

Abstract: Fire?flooding or in?situ combustion is an effective process for primary and secondary development of heavy oil reservoirs. Compared with water drive, this process is more complex, and few engineering methods can be used for studying production performance in fireflooding 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 performance data obtained from Wellblock Hongqian?1 in Karamay oilfield and Suplacu oilfield in Rumania. Relations among cumulative oil production, cumulative gas production and produced GOR can be established on the basis of the gas?drive type curve. Finally, recoverable reserves by fire?flooding process can be determined with the relations as the fire?flooding reaches the economic limits
