Abstract: Keeping injection water well compatiable with rocks and fluids in sandstone oil bears(especially for mid-and low-permeability is very important for reservoir pressure maintenance during waterflooding, and the extend of com-patibility is directly involving with the well injectivity. The water quality specifications must be limeted in a rea-sonable range to control formation damage, the specification evauation and determing strategy has been atudied in
this paper, a useful software has also been made to strenously manage the water injection system.

Key words: Water flooding, Water quality, Water quality criteria, Oilfield development, Sandstone, Forma-tion damage
