摘要： A method and apparatus for maintaining the single phase integrity of a deep well formation sample that is removed to the surface comprises a vacuum jacket insulated single working cylinder divided by two free pistons into three variable volume chambers. The intermediate chamber is pre-charged with a fixed quantity of high pressure gas. Wellbore fluid freely admitted to one end chamber bears against one free piston to further compress the gas. The formation sample is pumped into the other end chamber to first, displace the wellbore fluid from the first end chamber and, sequentially, to further compress the gas to preserve the sample phase state upon removal to the surface.

摘要翻译： 用于维持去除到表面的深井形成样品的单相完整性的方法和装置包括由两个自由活塞分成三个可变容积室的真空套绝缘单工作缸。 中间室预先装有一定数量的高压气体。 自由进入一端室的井眼液体抵靠一个自由活塞，以进一步压缩气体。 地层样品被泵送到另一端室中，以首先从第一端室移位井眼流体，并且依次地将气体进一步压缩以在去除表面时保持样品相状态。
