2024-06-10 10:00High temperature salt and filtrate reducing agent is used for drilling fluidR-12（Sulfonated material）
It can significantly improve the ability of the drilling fluid to resist paste salt and reduce filtration loss at high temperature.Used for filtration reduction of all kinds of fSulfonated materialresh water and 30% brine drilling fluid;Resistance temperature of 150 ℃ or more;Both have a certain dilution effect, especially in the high density drilling fluid in the basic viscosity.
Project | Index |
Appearance | Black brown powder |
Water content，% | ≤15 |
Reduction rate of high temperature and high pressure filtration loss of fresh water base slurry, % | ≥35 |
Apparent viscosity of fresh water base slurry after aging, mpa.s | ≤25 |
Reduction rate of high temperature and high pressure filtration of 15% salt water base slurry, % | ≥50 |
Apparent viscosity of 15% saline water base slurry after aging, mpa.s | ≤35 |
Add R-12 directly or into the drilling fluid as glue.The recommended dosage (dry agent) is 3 ~ 8%.
