SUMMARY
1、 Spacer additive, which can remove drilling fluid effectively, is able to prevent cement slurry from blending with it.
2、 Used below temperature of 120℃ (248℉, BHCT).
3、 Remarkable thickening effect and high viscosity with low-concentration. Good suspension effect on the weighing agents, insoluble solids and oil drops.
4、 Good synergy performance can be used with other thickening agents.
5、 Good thickening effect, suspending ability and stability. Easy to be dissolved and applied in water
6、 Compatibility test should be done before use.
7、 Has thickening effect on cement slurry under certain conditions, therefore, appropriate amount of chemical inert spacing agents should be applied to separate from the cement slurry. Fresh water or mixing water can be applied as chemical inert spacing agent.
