Vented non-pressurized, uncontaminated well fluid sampler |
摘要 |
A method is disclosed for recovering a non-pressurized and uncontaminated fluid sample from deep in a well or the like in an elongated sampler having a sample chamber formed by valves at both ends thereof in a tubular housing for trapping the fluid sample therein comprising, (1) venting the trapped sample fluid from one of the end valves into the well having a vertical portion extending at a predetermined distance above the sample chamber for (1) preventing detrimental pressure to build-up and (2) contamination of the sample fluid during ascent to the surface. A mechanism for carrying out the above method is also disclosed.
