METHOD OF WELL TESTING BY OBTAINING A NON-FLASHING FLUID SAMPLE |
摘要 |
Apparatus and method for testing a well and obtaining a fluid sample therefrom. The apparatus comprises a housing connectable to a tubing string and having a packer at the lower end thereof. The packer is set, and fluid is flowed from a formation or zone of interest into the chamber and then into a sampler in a controlled manner such that the fluid in the housing or sampler does not flash. In one embodiment, a pump is used to flow formation fluid; plugs are used in the housing to first flow dirty fluid and then flow clean fluid into the housing. In another embodiment, a nitrogen cushion is bled slowly to flow fluid into the housing.
