摘要： 已故学者翁文波先生曾于1984 年提出了利用逻辑斯谛旋回模型——— 翁氏逻辑斯谛旋回模型来预测油田的含水率和水油比, 并广泛应用于油田实践。通过对翁氏逻辑斯谛旋回模型的理论推导, 验证了John Fisher等人(1970)所提出的经验公式(R wo =be at/ c)的不合理性;同时, 通过油田实际应用, 提出了翁氏逻辑斯谛旋回模型的有效适用范围是在油田中期含水以前, 即仅适用于含水率低于70%以前的油田的含水率和水油比预测。

Abstract: The late Mr.Weng proposed logistic cycle model in 1984, which can be used to predict watercut and water-oil ratio and widely applied in oilfields. Based on the deduction of Weng' s logistic model in theory, this paper verified the unreasonableness of empirical formula(WOR =be-at/c)presented by John Fisher.Meanwhile, on the basis of field application of it, it is pointed out that Weng's logistic model is applicable to predict watercut and water-oil ratio of oilfields which current water cut is less than 70 %.
