TG—2油井水泥降滤失剂的研究与应用

Research and Application of TG-2 Fluid Loss Control Agent for Cement Slurry.

摘要: 叙述了固井用降滤失剂ＴＧ－２的室内研究和现场试验情况，ＴＧ－２是由多溶性高聚物ＳＰＶＴ和ＳＶＴ与分散剂ＰＮＳ按一定比例复配而成的，具有降滤失效果好，改善流变性，降低自由水，对稠化时间和水泥石强度影响小，并与其它外加剂配伍良好等特点。

Abstract: This paper introduces the laboratory test and field experiment of TG-2 fluid loss control agent for well cementing. TG-2, formulated with two water soluble polymers (SPVT and SVT) and a dispersant PNS, can provide excellent fluid loss control performance,
