摘要

现场录井过程中，准确计算油气上窜速度为指导钻井安全、检验地层压力提供了重要依据。新计算方法考虑了下钻过程中钻具的排替作用对油气上窜高度的影响和其它影响因素，在一定程度上提高了油气上窜速度的精度。

Abstract

In the process of logging, the accuracy of gas upward flow velocity calculated is very important because it serves as the important basis for safely drilling and formation pressure surveying. The new calculation method in this paper takes into consideration of the influence of displacement of drilling tool on the gas channeling height during running in the hole as well as other influence factors. To a certain extent, this method can improve the accuracy of calculation.
