The upwarping phenomenon of water-flooding characteristic curves at high water-cut stage influenced the precise prediction of recoverable reserves and oil recovery. 水驅特征曲線(xiàn)在高含水開(kāi)發(fā)期的上翹現象影響到可采儲量和采收率預測的準確性。
This paper accordingly introduces a derivative curve of waterflooding characteristics based on derivative sensitivity and presents the calculation method. 針對這一問(wèn)題，基于導數的敏感性特征，引入水驅特征導數曲線(xiàn)，并給出相應的計算方法。
