摘要
依据蒸汽吞吐稠油油藏注采特征曲线,当汽油比(SOR)大于1～2.5时,曲线在半对数坐标上出现直线段。直线的斜率与静态石油地质储量密切相关,由此建立的经验方程计算稠油油藏动态石油地质储量,平均相对误差3.48％。
In the injection-production curves of producing heavy oil, a straight line segment appears in semi-log coordinate system when SOR greater than 1 to 2.5. And there is relation of slop of straight line with the reserve. According to this relation, an equation of calculating dynamic reserve is established. Calculating average error is 3.34%.
