九江二井汞观测对比试验研究

Contrast Experiment on Mercury Observation at Jiujiang No.2 Well

针对九江二井测汞仪老化、观测效率下降的现象,引进新型高精度ATG-6138M测汞仪并对井口装置进行改进,数字化汞观测质量得到显著提升。通过对九江二井汞观测系统改进过程的介绍及改进前后汞观测数据的对比分析,认为井口装置与观测仪器良好耦合是取得连续、稳定汞观测资料的关键。

According to the aging and observation efficiency falling of measuring mercury instrument at Jiujiang No.2 well. High precision ATG-6138M measuring mercury instrument was introduced and well-head equipment was reformed, digital observation of mercury got promoted significantly. This paper introduces process of improvement about mercury observation system and compares mercury observation data before and after. The results show that good coupling between well-head equipment and observation instrument is the key of continuous and stable mercury observation data.
