Volume equivalent-based oil and gas upward moving average speed calculation method for oil well

The invention discloses a volume equivalent-based oil and gas channeling average speed calculation method for an oil well, which comprehensively considers factors such as a well body structure, a drilling tool replacement effect, pump displacement change, gas logging pipeline delay time, booster pump use and the like. The oil and gas channeling height is represented according to the difference between the oil layer depth and the empty well volume equivalent homing depth (or volume equivalent homing depth), and the oil and gas channeling speed is obtained by dividing the oil and gas channeling height by the total oil and gas channeling time. The volume equivalent refers to the sum of the volumes of the calculation parts. The method is suitable for calculating the average oil and gas channeling speed during drilling and completion of different well types (vertical wells, directional wells and horizontal wells) of land oil fields and offshore oil fields. 本发明公开了一种基于体积当量的油井用油气上窜平均速度计算方法，该方法综合考虑了井身结构、钻具替代作用、泵排量变化、气
