根据渤中34-2/4油田注入水与地层水特征，通过结垢软件预测了注入水与地层水的结垢趋势，静态结垢实验得到了注入水与地层水的结垢量，动态结垢实验评价了注入水结垢对岩心渗透率的伤害程度。结果表明，该油田注入水与地层水相容性较差，注入过程中会产生碳酸钙垢，最大结垢量为1199mg/L，结垢量为800mg/L时，岩心渗透率伤害程度较大，达到32％。对比了有机磷酸和聚合物两大类共6种阻垢剂的阻垢效果，确定了针对该油田阻垢效果较好的为PBTCA阻垢剂；加入该阻垢剂后，静态阻垢率达85％，动态实验中岩心渗透率的伤害程度降低到13％。

Comprehensive evaluation in Bozhong 34-2/4 oilfield has been made via software , static and dynamic scaling experiments .The results show that incompatibility between the injection water and formation water and calcium carbonate scale would produce during injection process ,it’s scaling reached 1 199 mg/L .When scaling of 800 mg/L ,core permeability damage up to 32% .Scale studies of the six kinds of inhibitors suggest that ,for this oilfield ,inhibitor PBTCA has better anti-scaling effect ,static-scaling reduced by 85% and core permeability damage reduced approximately by 13% .
