摘要: 就无荧光降滤失剂GT-68对钻井液性能的各种影响进行了较系统的评价,并与磺化沥青FT-1、FH-1作了对比实验。实验结果表明:GT-68具有良好的降失水、悬浮、抑制(防塌)、润滑、抗温(80℃以上)、无荧光等性能,并能与两性聚合物FA367、XY27、JT888或NPAN、MMH等很好配伍,且复配后钻井液体系的失水造壁性及抑制能力变得更佳;无荧光降滤失剂GT-68完全可替代磺化沥青,它消除了磺化沥青普遍存在的负面影响,其总体效能优于磺化沥青FT-1、FH-1。

Abstract: The effect of GT-68 on the performances of drilling fluid has been investigated and compared with sulfonated asphalt products like FT-1 andFH-1. Results have showed that GT-68 has such good properties as filtration control, suspension,inhibition, lubrication, anti- temperature and non- fluores-
cence. It can be compatible with some amphoteric polymers FA367, XY27, JT888 et al, which greatly improved the char-acteristics of drilling fluids in its fluid loss and wall building as well as inhibition. GT-68 can completely replace the sulfonat-ed asphalt without side effects.

Key words: drilling fluid treating, multifunction, fluid loss additive, non-fluorescence, environmental protection
