The currently used methods for calculating gas injection rate during gas drilling all take the temperature of natural formation at the same depth as the temperature of the annulus fluid,without considering the heat exchange occurred between the wellbore fluid and the formation.
目前关于气体钻井时所需注气量的计算方法均是将环空流体的温度取同一深度的自然地层温度来进行计算,没有考虑井眼内流体与地层进行换热的影响,这必然会带来误差。
6) well bore
井眼
