Embodiment 1
[0031] This example is used to illustrate the synthetic ester lubricant for water-based drilling fluid of the present invention.
[0032] (1) Mix 1 mol stearic acid, 0.5 mol ricinoleic acid, 0.8 mol xylitol and 0.7 mol triethanolamine and carry out esterification at 80°C for 4 hours;
[0033] (2) Add water (based on 100 parts by weight of the product of the above-mentioned esterification reaction, its consumption is 10 parts by weight) and γ-[(2,3)-glycidyloxy] to the product of the above-mentioned esterification reaction Propyltrimethoxysilane (10 parts by weight based on 100 parts by weight of the product of the above esterification reaction) was stirred and mixed for 2 hours, and the resulting mixture was synthetic ester lubricant L1.
Embodiment 2
[0035] This example is used to illustrate the synthetic ester lubricant for water-based drilling fluid of the present invention.
[0036] (1) Mix 0.8 mol of palmitic acid, 0.6 mol of linoleic acid, 0.4 mol of maltitol and 1 mol of n-butanol and carry out esterification reaction at 90°C for 3 hours;
[0037] (2) Add water (based on 100 parts by weight of the product of the above esterification reaction, the amount is 7 parts by weight) and γ-(methacryloyloxy) propyl trimethoxy base silane (based on 100 parts by weight of the product of the above-mentioned esterification reaction, the amount used is 13 parts by weight), stirred and mixed for 2 hours, and the resulting mixture is the synthetic ester lubricant L2.
Embodiment 3
[0039] This example is used to illustrate the synthetic ester lubricant for water-based drilling fluid of the present invention.
[0040] (1) Mix 1.5 mol of stearic acid, 0.5 mol of ricinoleic acid, 1 mol of xylitol and 1 mol of triethanolamine and carry out esterification at 100° C. for 4 hours;
[0041](2) Add water (based on 100 parts by weight of the above-mentioned esterification product, its consumption is 5 parts by weight) and vinyltriethoxysilane (based on 100 parts by weight of the above-mentioned The product of the esterification reaction was used as a reference, and the amount used was 15 parts by weight), stirred and mixed for 2 hours, and the resulting mixture was the synthetic ester lubricant L3.
