| titleOfInvention | A kind of content of wax viscous crude wax crystal dispersing agent and preparation method thereof |
| abstract | The invention discloses a kind of content of wax viscous crude wax crystal dispersing agents and preparation method thereof.The wax crystal dispersing agent by raw material of maleic anhydride and high fatty amine according to molar ratio be 1: 1~1.8 reacted after carry out dehydration again and be prepared, the high fatty amine is one of tetradecy lamine, cetylamine, octadecylamine and 20 amine.The raw material sources of wax crystal dispersing agent of the invention are extensive, and synthesis technology is simple, and process cleans are pollution-free, and product is easily obtained and transports preservation；Wax crystal dispersing agent anti-salt property of the invention is good, and resistance to salinity reaches 210000mg/L；Wax crystal dispersing agent of the invention simultaneously can be used in compounding with a variety of pour-point depressants, significant effect, under conditions of being compounded with pour-point depressant, when dosage is 100ppm, it can make the freezing point decreasing value of content of wax viscous crude more 4 DEG C or more compared with single pour-point depressant, to improve the depression effeCt of pour-point depressant.Therefore, wax crystal dispersing agent of the invention can be widely used in the pour point depression field test of high-content wax heavy oil wells. |
