摘    要:针对目前水驱特征曲线理论研究中的不足 ,提出了一种通用推导水驱特征曲线的理论方法。该方法主要从油、水两相渗流特征曲线出发 ,充分考虑到油田一般都有无水采收期 ,利用定积分导出了不同油、水两相渗流特征下带有校正项的完整形水驱特征曲线 ,从而揭示了渗流特征与水驱特征的内在联系 ,体现了油、水两相渗流特征是水驱特征曲线的决定性因素

关 键 词:采油 水驱特征曲线 渗流理论 推导方法

Abstract:According to the deficiency in previous theoretical s tudy on the displacement characteristic curves, this paper presents a general me thod used to derive displacement characteristic curves. This method, from basic curves of oil water relative permeability, taking full account of the water fr ee recovery period which is usually seen in the oil fields, derives the integral ity water drive charac teristic curves with corrected item under the condition of different oil water relative permeability by the use of finite integral. In brief, it brings to ligh t the internal relation between percolation and water driving characters ,and de monstrates that the oil water two relative permeability is the foundational an d determinate factor influencing the displacement characteristic curve.
Keywords:Water drive  Displacement curves   Percolation   Fea ture   Curve   Theory   Research   Method
