| titleOfInvention | Well killing and leakage blocking slurry for well completion and oil testing and leakage blocking method thereof |
| abstract | The invention discloses a well killing and leakage blocking slurry for well completion and oil testing and a leakage blocking method thereof, which relate to the technical field of petroleum and natural gas well completion test engineering, wherein the leakage blocking slurry is based on conventional well completion and well killing fluid, and compared with the conventional well completion and well killing fluid, the leakage blocking slurry comprises the following components in percentage by mass: A. plugging agent while drilling SDL: 4.5% -5.0%; B. temporary plugging agent PCC for drilling fluid: 4.0% -5.0%; C. composite plugging agent FDJ-I: 3.0% -5.5%; D. flexible reticular fiber plugging agent AT-FB: 0.2% -0.5%; adjusting the density of the leakage-stopping slurry to 1.85g/cm 3 ‑1.93g/cm 3 And the concentration is 15.4% -16.4%, and the packer is circularly injected into the deblocking packer for plugging. By adopting the leakage blocking slurry, the phenomena that the packer and the sleeve are blocked to cause unsmooth setting or deblocking can be prevented, and the blocking accident of the perforating test tubular column caused by the blocking of the gap between the perforating gun detonation impact rod and the oil pipe can be prevented. |
