摘要
通过研究稠油油藏有关参数及井网密度与蒸汽吞吐采收率的关系 ,利用回归方法及多种公式对比 ,确定出一种新的蒸汽吞吐方式下的采收率预测公式。与其它公式相比 ,该公式考虑到井网密度对采收率的影响程度 。
A new recovery factor estimation formula for cyclic steam stimulation is determined using regression and formula correlations through study of heavy oil reservoir parameters and relations between pattern density and recovery factor of cyclic steam stimulation. Compared with other formulas, it is more applicable due to its considerations of effect of pattern density on recovery factor.
