摘要
本文介绍一种新型油井水泥降滤失剂G402．评价了它的性能及与其它外加剂配伍性。该外加剂具有降滤失效果好，稠化时间易调，流变性好，析水率低，适用的温度范围广等优点。经20余口井的固井试用，固井合格率达100％，优质率达75％，取得了满意的效果。
This article introduce a new filtrate bo reduction additive-G402 for oil well cementing and evaluating its properties and compatibility with other additives. This new additive have advantage with a gnd effect of filtrate las reduction, easy adjusting thickening time, good rheological property, low water abeorption rate and suit for large temperature range. The test results have shown the gnd effect with qualification rate of cementing abtained is 100%, and high quality rate is 75%, through applications in cementing jobs about 20 wells
