温度对HSG冻胶体系流变性的影响

The influence of temperature on the rheological properties of profile modification gel HSG

测量了HSG冻胶体系的屈服应力,蠕变-回复和粘弹性参数,研究了温度对其流变性的影响．结果表明,HSG冻胶体系的屈服应力随着温度的升高而明显下降,超过冻肢体系屈服应力之后很快达到稳定的平衡应力值,温度对其影响很小．温度越高,冻胶的柔量越大,越易变形．HSG冻胶体系具有高弹低粘特性,随着温度的升高,冻胶弹性明显下降,但粘性下降不大．温度越高,冻胶线性粘弹性区域越小．

The rheological parameters of profile modification agent gel HSG was measured and the influence of temperature on the rheological properties was investigated. The results showed that HSG＇s yield stress point decreases significantly with increased temperature, the compliance increases with increased temperature, the linear visco-elastic area of HSG narrowed down with increased temperature. HSG has the property of high elastic and low viscous. The elastic property decreases significantly with increased temperature while the viscous property ＇s almost not affected by temperature.
