摘　　要：油田产量出现递减以后,无因次累计产量与无因次时间在直角坐标中是一条通过坐标原点斜率为1的直线,用这个直线方程可以预测任何油气田的产量变化动态。将这个无因次方程与甲型、丙型水驱特征曲线相结合,得到了两个预测油田含水率变化动态的经验公式,用这些公式预测油田含水率变化,结果是令人满意的。在介绍这一预测方法的基础上,运用国内外2个油田开发实例比较详细的说明了上述预测方法的应用过程,预测结果表明,与油田实际开发指标相吻合。Since the production decline of the Oil Field, the dimensionless cumulative production and dimensionless time in the Cartesian coordinate system present a straight line passing the true origin with unit slope; the straight line equation could be used to predict production dynamic changing of any Oil Field. The dimensionless equation integrating respectively with Jia -type and Bing -type water drive indicatrix will get two water cut changing dynamic forecasting experiential equations with satisfactory forecasting results. Examples of two field cases both at home and abroad demonstrate the application of the above method in detail; the forecasting results coincide with practical development indexes.
