本文主要介绍了通过理论分析和实际测定数据的综合,得出:1、校正大气压变化的气压计不应安放在井底车场附近,必须安放在地面井口附近,同时气压计安放处一定要避开任何外界的干扰及避开阳光的直晒;2、在测定过程中,为了保持容器小的温度恒定,不得把保温瓶中冰融化的水抽出,为了使容器中的煤油和空气与保温瓶中的温度平衡后再进行测定,应提前一天把冰装入保温瓶,测定前再更换新冰块。
This paper mainly introduces the theoretical analysis and the actual measured data synthesis, drawn: 1, barometric pressure gauge to correct the barometer should not be placed near the bottom of the well, must be placed near the wellhead in the ground, while the barometer place to be sure to avoid Any external interference and avoid direct sunlight; 2, in the determination of the process, in order to maintain a small container temperature constant, not to melt the ice in the thermos flask out of water, in order to make the container of kerosene and air and thermos After the determination of the temperature balance, the ice should be placed in a thermos flask one day in advance, before measuring the replacement of new ice.
