摘要 在试井解释线性流分析法、压裂井压力恢复试井直接综合分析技术基础上,提出了预测—检验法。该方法利用压力导数和时间双对数图中拟合的直线与平行于纵轴的直线(t=1h)交点坐标完成各项分析参数的预测和检验,提高了解释结果准确性。通过实例对其实用性进行了验证。 Based on linear flow analysis method and direct comprehensive analysis technique for well test interpretation of fractured wells,this paper proposes a forecasting and checking method.This method uses the coordinates of the intersection point of the matched straight line and the straight line (t=1h) in log-log plot of pressure derivative vs.time to do the parameters forecasting and checking,and so improves the accuracy of interpretation results.The method has been verified by field examples.
