摘　　要：油气上窜速度是现场录井的重要参数之一,随着深井和超深井的开发,传统的迟到时间法和容积法已经不能满足现实的需要。因此提出了一种计算油气上窜速度的方法——分段判定累计泵冲法。分段判定累计泵冲法可以有效解决深井在起下钻过程中分段循环时油气上窜速度的准确计算问题。经过在实际中的应用论证,该方法可以在青海油田区块进行推广使用。The upwelling velocity of oil and gas is one of the important parameters of on-site logging.With the development of deep and ultra-deep wells,traditional lag time method and volumetric method can no longer meet the needs of reality.Therefore,a method for calculating upwelling velocity of oil and gas named segmented identification of cumulative pumping method is proposed.It can realize accurate calculation of oil and gas upwelling velocity during segmented circular of deep wells being tripped in and tripped out.After practical application and demonstration,this method can be promoted and adopted in blocks of Qinghai Oilfield.
