A Productivity Prediction Model for Heavy Oil Steam Huff and Puff Considering Steam Override

  • 摘要: 常规稠油油藏蒸汽吞吐产能预测模型假设注入蒸汽活塞式驱替原油,油层顶底加热面积相同,实际生产过程中,由于原油和蒸汽密度不同产生重力分异作用,出现蒸汽超覆现象,导致油层顶部加热面积大于底部加热面积。通过确定顶底盖层加热半径之间的关系,引入等效半径,在拟稳态产量公式基础上,建立了考虑蒸汽超覆的蒸汽吞吐产能预测模型。以孤岛油田M区块为例,分别采用本文模型、Marx模型和商业模拟器CMG计算产能。模拟结果表明,Marx模型由于未考虑蒸汽超覆现象造成热损失较小,预测产能偏高,平均相对误差为41%,而本文模型计算结果平均相对误差为12%,最小相对误差为7%,与商业软件计算结果较吻合。研究结果表明,考虑蒸汽超覆的稠油蒸汽吞吐产能预测模型具有一定可靠性,可用于稠油油藏蒸汽吞吐产能预测。
