气井关井井底压力计算,常用井筒气柱平均温度计算。对于部分气井,由于关井以后井筒气柱温度的改变,致使关井压力恢复资料无法处理。为了找出井筒气柱温度与关井时间的关系,中坝气田须二气藏中29井于1981年4月19日9:00～4月24日15:00关井实测不同深度井筒气柱温度(以下简称井温)资料24个点(见中29井实测井温资料表)。 Gas well shut-in bottom hole pressure calculation, common wellbore air column average temperature calculation. For some gas wells, due to the change of wellbore air column temperature after shut-in, the data of shut-in pressure recovery can not be processed. In order to find out the relationship between the wellbore gas column temperature and the time of shut-in, the 29 wells in the Zu-2 gas reservoir in Zhongba gas field were closed at 15:00 on April 19, 19:00, April 19, Temperature (hereinafter referred to as well temperature) data 24 points (see wells in 29 well measured temperature data sheet).
