摘　　要：本文在章氏标准公式的基础上,通过引进校正系数a、c提出校正公式,可对复杂断块油田,特别是标定采收率较低的早期含水率进行预测,通过对实际生产数据的应用对比,其误差小,可应用于新开发油田的早期含水率预测。On the basis of the Tong-xianzhang's standard equation, This paper presents a corrected equation. By introducing the corrected coefficients, a and c. The corrected equation can predict the initial water cut of the complex fault-block oil field, especially when the demarcated oil recovery efficiency is low, The error is very small when it is compared with the practical production data. So it can be applied to predict the initial water cut of the new development blocks of an old fields.
