本文运用正交试验法对影响无能量补充井采收率的主要因素进行了敏感性分析。计算结果表明, 对采收率影响程度的显著性依次为: 流体性质和油气相对渗透率、地层能量、井位和渗透率。并以此为依据, 结合无能量补充井的开采特征, 提出了提高采收率可开展的几项工作。

The orthogonal experimental method is used to do sensibility analysis on influencing recovery factors of no energy-feeding wells. The calculating result shows that the significant order of influencing recovery factors is: fluid property and relative permeability of oil and gas formation energy well site and permeability. Based on this, combining with the developing characteristics of the wells, a several techniques to enhance oil recovery are provided.
