摘要:

着重介绍了一种新型抗高温降滤失稳定剂SPNH(改进型)及其室内实验情况。结果表明,SPNH(改进型)具有降失水、降粘作用,抗温能力强,抗盐性好,热稳定性好,成本低,其效果明显优于同类磺化系列处理剂。

Abstract:

This paper describes the experimental study of improved filtration reducer SPNH at high temperature. Experimental results show that the improved SPNH is capable of reducing filtration and viscosity, is anti-temperature and antisalt, and has high thermal stability and low cost. Its performances are remarkably better than other cognate sulphonated additives.
