摘　　要：白音查干油田地层水具有高SO42-、Cl-、高矿化度的特征,水型大都为Na2SO4型。试验表明:油井产出水混合、混合水注入油井后均会产生结垢现象,配伍性较差。但经净化、絮凝、过滤及阻垢处理后,能够达到混合回注对水质的要求。Formation water of the Baiyinchagan Oilfield is the high S042- , Cl- and high salinity properties. Formation water mostly is Na2SO4 type. Testing has indicated that blend water which is produced from well after processing is injected back to the well, which always create a tendency of the incrustation forming with poor matching property. After the blend water is purified, flocculated, filtered and incrustation-blocking processed,it can meet the requirements of the water quality for injecting back to the well.
