| titleOfInvention | A kind of pipeline, which moves, changes engineering oil recovery systems |
| abstract | It is moved the invention discloses a kind of pipeline and changes engineering oil recovery systems, belonged to oil pipeline and move and change engineering Oil Recovery technical field.The system comprises new pipeline of relocating, old pipeline of relocating, nitrogen vehicle, fast exploitation ball cylinder, combined spheres, Oil Recovery boosting controller, fast exploitation ball cylinder and stopple plugging machines.System injects nitrogen and high-pressure oil pump as power source using nitrogen vehicle, nitrogen pushes combined spheres to advance, combined spheres push the oil product relocated in old pipeline to flow into Oil Recovery boosting controller, it is rapidly injected in new pipeline by high-pressure oil pump pressurization, overcome that traditional high point air inlet low spot oil extraction security risk is more, and risk is big, and return period is long, it is costly, the shortcomings that oil quality cannot be guaranteed. |
