摘要
就无荧光降滤失剂GT - 6 8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 - 6 8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FA36 7、XY2 7、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 - 6 8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。
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-fluorescence. It can be compatible with some amphoteric polymers FA367, XY27, JT888 et al, which greatly improved the characteristics of drilling fluids in its fluid loss and wall building as well as inhibition. GT-68 can completely replace the sulfonated asphalt without side effects.
