摘　　要：水驱特征曲线在中国可采储量标定中占有重要地位,正确理解和把握其使用条件是用好水驱特征曲线的关键。长期以来关于“水驱特征曲线对原油粘度是否具有选择性”的学术分歧,在一定程度上影响了水驱特征曲线的广泛使用。通过大量的油藏实例,从多个角度研究了水驱特征曲线与原油粘度的关系,证明了水驱特征曲线对原油粘度不具有选择性。Waterflooding characteristic curve has an important role in calibrating recoverable reserves in China. The key is how to understand and use waterflooding characteristic curve correctly. An argument whether or not waterflooding characteristic curve is selective to crude oil viscosity for a long time has some influences on using the waterflooding characteristic curve widely. Based on lots of oil reservoir cases,the relationship between the waterflooding characteristic curve and the crude oil viscosity is studied in different views, and it proves that the waterflooding characteristic curve is not selective to the crude oil viscosity.

关 键 词：水驱特征曲线 原油粘度 选择性
