2024-06-12 10:00Salt resistant polymer filtration reducer for drilling fluid R-23（EPMC）Salt resistant polymer filtration reducer
The product is made of modified natural polymer and synthetic polymer, which react under certain temperature and pressure. It can significantly improve the salt resistance and filtration loss reduction performance of drilling fluid, maintain the rheological property of mud during drilling, and have certain temperature resistance effect. It is a kind of broad spectrum filtration loss reduction agent.
1, suitable for all kinds of fresh water, salt water, saturated salt water drilling fluid filtration;
2. Suitable for filtration loss reduction of various low-density, medium-high density and ultra-high density drilling fluids and completion fluids;
3, both have a certain dilution effect, especially in ultra-high density drilling fluid viscosity;
4. Strong salt resistance.
