SYSTEM AND METHOD FOR COLLECTING A REPRESENTATIVE FORMATION FLUID DURING DOWNHOLE TESTING OPERATIONS |
摘要 |
A method for collecting a formation fluid for testing includes introducing a formation sample tool having a first port and a second port into a wellbore. A first fluid is injected through the first port into the formation to clear a sample passage and allow access to uncontaminated formation fluid. A second fluid is injected through the second port into the formation to provide a barrier adjacent to or around the sample passage. A sample of the uncontaminated formation fluid is removed from the formation through the first port. |
