摘要

摘要: 规范钻井液处理剂产品的使用范围，使处理剂达到更好的使用效果，是当前需要重视的问题。以SMP-Ⅰ和SMP-Ⅱ为例，从其组构特征、生产工艺及其在钻井液中降低滤失量和抗盐的作用机理等方面分析，讨论了磺甲基酚醛树脂SMP-Ⅰ和SMP-Ⅱ的应用范围，并比较了不同生产工艺的产品其抗盐抗温性能的差别。实验结果表明，在含盐量低于2%的钻井液中、井温不大于180℃的情况下，SMP-Ⅰ比SMP-Ⅱ的使用效果好；在井温为120℃与150℃时，SMP-Ⅰ可用于不同含盐量直至饱和的盐水钻井液，而SMP-Ⅱ只适用于含盐量高于25%的近饱和/饱和盐水钻井液；在井温为180℃下，SMP-Ⅰ可用于含盐量低于20%的盐水钻井液，而SMP-Ⅱ适用于含盐量高于20%的近饱和/饱和盐水钻井液。

Abstract: Drilling fluid additives should have their range of use clearly defined to make the best use of them, and great attention should be paid on this issue. Take the SMP-Ⅰ and SMP-Ⅱ as examples, the application characteristics, production technology, and the mechanisms of reducing filtration rate and resisting salt contamination are analyzed in this paper. The ranges of use of SMP-Ⅰ and SMP-Ⅱ are discussed and the differences in high temperature and salt-resistant performances of the two additives manufactured by different production technologies are compared. Laboratory experiment has shown that in drilling fluids with salinity less than 2%, and borehole temperature below 180℃, the performance of SMP-Ⅰ was better than SMP-Ⅱ. At 120℃ and 150℃, SMP-Ⅰ worked well in different salinities up to saturation, while SMP-Ⅱ only functioned in drilling fluids containing 25% salts or in under-saturated and saturated drilling fluids. At 180℃, SMP-I can be used in saltwater drilling fluids with salinities less than 20%, while SMP-Ⅱ can be used in saltwater drilling fluids with salinities greater than 20% to saturation.
