An increase in trip gas due to the above condition 由于上述情况，起下钻后效增大。
Then comes the main event , the full round trip 然后进入主题时刻，即进行整个起下钻作业。
We test trip gas at every trip 每次起下钻我们都要进行后效测量。
Number stands on trip out and trip in 起下钻时给立柱编号

Any increase in the background , connection , and / or trip gas trend ( s ) 钻井液含气量、井内气侵量、起下钻后效有任何增加趋势。
Make a short trip 进行短途起下钻
Control trip gas 控制起下钻气
Perhaps there will be a short trip to test the possibility of a blowout - in case the will is acting up 当井的情况不好时，也许要进行为时较短的起下钻作业来试验井喷的可能性。
Lagged indicators such as background , connection , and trip gas ; cuttings size and shape ; flowline temperature changes 后效判断法，钻井液含气量、井内气侵量、起下钻后效、岩屑形状与大小、出口温度变化。
