Abstract EN
After synthesis of mixed fatty acid triethanolamine ester surfactant based on animal and vegetable mixed oils, the reaction solution was added into 4% (wt/wt) liquid nitric acid or 9% (wt/wt) solid nitric acid as eliminating fluorescent agent continuing to react from 1 to 2 hours.
The low fluorescence lubricant named E167 for drilling fluid was prepared, in which maximum fluorescence intensity (Fmax) was less than 10 in three-dimensional fluorescence spectra of excitation wavelength range.
When the E167 was added into fresh water based drilling fluid at the dosage of 0.5% (wt/wt), the sticking coefficient reduced rate (ΔKf) is 78% and the extreme pressure (E-P) friction coefficient reduced rate (Δf) is 79%.
In the case of 4% brine mud with 0.5% (wt/wt) E167 in it, the ΔKf and Δf are 75% and 62%, respectively.
After the hot rolling ageing test 180°C × 16 h with the E167 was added into fresh water based drilling fluid at the dosage of 1% (wt/wt), the ΔKf and Δf are greater than 70%, which shows a much better lubrication properties of strong resistance to high temperature.
The fresh water based drilling fluid which contains 1% (wt/wt) E167 is almost nonfoaming even after hot rolling ageing 120°C × 16 h.
