Chemical description
RHEOLOGICAL SPACER SYSTEM - A COMPOSITION DEVELOPED FOR PREPARING WATER-BASED BUFFER FLUID, DESIGNED TO PREPARE THE WELLBORE FOR CEMENTING, WHICH CAN BE APPLIED WITH DRILLING FLUIDS BOTH ON WATER AND HYDROCARBON BASES.
Physical properties
Appearance: solid powder, ranging from gray to dark brown color
Properties of cement stone
Bulk density: 500-900 kg/m3
Advantages
- Effective displacement of drilling fluid;
- Presence of abrasive particles allows for better cleaning of the wellbore;
- Ability to retain solid phase in suspended state.
Application
- All types of well cementing;
- Can be used at temperatures up to 140°C;
- Designed to prepare buffer fluids in the range of 1.2 – 1.75 g/cm³;
- Sealing in both fresh and saltwater.
Compatibility
The ready-made RBS™ buffer composition is compatible with most cement slurries and water-based drilling fluids. This buffer fluid can also be used with hydrocarbon-based drilling fluids when special surfactants are added for more effective displacement during wellbore preparation.
Packaging and storage conditions
