U形管采样技术研究

Research on the Sampling Technique with U-tube

深部流体样品是深井工程的重要组成部分,介绍了获取深部流体样品的一种方法——U形管采样技术。通过对U形管采样技术原理进行研究分析,设计研制U形管取样器具并进行野外试验,取样深度达到井深500 m,最大流量达到40 L/h,取得了较好的效果。

Fluid samples from deep boreholes can provide a variety of information, which is an important part of deep drill-ing engineering.This paper introduces a technology for borehole fluid sampling-U-tube sampling technology.By the re-search and analysis on the principles of U-tube technique, U-tube sampler was designed and developed with field tests;the sampling depth reaches 500m and the maximum flow is up to 40L/h.
