技术领域 technical field
本实用新型属于井下微生物取样技术领域，具体涉及一种井下微生物取样装置。 The utility model belongs to the technical field of downhole microbial sampling, in particular to an downhole microbial sampling device.
背景技术 Background technique
目前，煤层气井、水井、石油井液体中的微生物采样主要是通过井口排出液获得。这种采样方法通常是将井口排出液收集起来直接获得微生物样品。但是在外界环境比较恶劣如大风、扬尘等的条件下，很容易造成样品污染。当液体中微生物数量较少时，所采样品不经过过滤很难满足要求。而且有时候如果厌氧要求比较高，传统的取液和过滤方式就很容易造成微生物接触空气而死亡，取样质量就不能达到要求。 At present, microbial sampling in coalbed methane wells, water wells, and oil well fluids is mainly obtained through wellhead effluent. This sampling method usually collects the wellhead effluent to obtain microbial samples directly. However, under harsh external conditions such as strong winds and dust, it is easy to cause sample contamination. When the number of microorganisms in the liquid is small, it is difficult for the sampled product to meet the requirements without filtering. And sometimes if the anaerobic requirements are relatively high, the traditional methods of liquid extraction and filtration can easily cause the death of microorganisms in contact with the air, and the sampling quality cannot meet the requirements.
