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
