摘　　要：在长期观测中,川32井经常出现不明原因的变化,经现场调查分析发现流沙堵塞和模拟观测取水是干扰川32井观测质量的主要因素。经过对比实验后进行了井口装置改造。改造后5个月的观测结果表明:流沙堵塞、模拟观测取水对数字化观测的干扰问题得到解决。There are always some unexplained abnormal data changes of No. 32 well during our past long-term observation. Field investigation and analysis indicate that sand jams and manual water taking for the analogue observation are two main reasons which effect the quality of the fluid observation. After experiments, we rebuilt the wellhead. After 5 months observing, the data shows that the problem of sand jams and manual water taking has been resolved.
