一种处于地层压力下流体除砂装置的应用

摘要

介绍了一种专门用在海上探井地层测试中转样时的除砂装置,连接于取样器与样瓶之间,通过使用该装置,有效的避免了地层流体中的砂粒堵塞样瓶的针阀,保护了地层流体的顺利转样.该装置已多次应用于出砂地层的地层流体样品转样过程中,均取得良好效果.%This paper describes a fluid sand removal device connecting the sampling bottle and sampler used for formation tests of offshore exploration.The application of the device can avoid the sand in formation fluid blocking the needle valve of the sampling bottle so as to ensure the sample transferring.It has been used in many cases of transferring for sand formation with good results.
