| Abstract: | Changqing oilfield is a typical low permeability or extremely low permeability oilfield. Water injection capacity is one of the important factors affecting waterflooding response. The factors of formation plugging are comprehensively analyzed, including the influence factor of injected water quality, the compatibility and sensitivity of injected water and formation water. |
| |
| Keywords: | low permeability oilfield plugging mechanism water quality scaling sensitivity compatibility Ansai oilfield |
