There are various formation damage in the exploitation of shale oil, for example water blocking, water sensitive and incompatibility, and so on, which will influence the recovery period and recovery rate of oil well. In this paper, an Anti-Scale technology for high density brine killing fluid was researched. The result show that the brine killing fluid can withstand high salinity (Ca 2+ <180000mg/l, NaHCO 3 <10000mg/l), and has well compatibility with common formation water. The puzzle for the scaling of high density brine kill fluid has been resolved.
