抽油机井节点分析方法及应用

METHOD OF NODULE ANALYSIS OF PUMFING WELLS ANDITS APPLICATION

本文根据油田生产的实际情况,对预测油井IPR曲线的Vogel方程和Brown提出的计算泵吸入口压力的公式进行了修正,修正后的数学模型考虑了较多的因素,完善了抽油机井节点分析方法。油田实际资料计算表明:修正后的数学模型比较符合抽油机井的实际生产情况,并且计算结果的精确性较好。

<ABSTRACT> Based on the actual production of an oilfield, Vogel equations for prediction the IPR curve of oil wells and formulas for calculating the entrance pressure mentioned by Brown are corrected.The corrected mathe matical model considers many factors, perfecting the method of nodule analysis ofpumping wells. The actual calculation at the oil field shows that the corrected mathematical model is more in accordance with the actual produc- tion ilnd the accuracy of the calculation is better.
