Glass Bubbles for Low Density Drilling Fluids

Hollow Glass Microspheres is a Free Flowing White Powder and showed to be hollow sealed sphere under microscope. Application Hollow glass microspheres have a significant effect to reduce weight and noise insulation, make the products have good anti-cracking performance and re-processing performance, is widely used in glass, steel, artificial marble, artificial agate and other composite materials, and the oil industry, aerospace , new high-speed train, car ferry, insulation coatings and other fields.

Low density drilling fluids made with hollow glass microspheres:

1) Adjustable density in a wide range

2) Incompressible and uniform in density

3) Good lubricity, Reduce drilling tool wear

4) No pollution for reservoir

5) Good stability at high temperature and pressure

6) No loss of MWD signal

7) Mud cake quality improved





Low density cement slurries made with hollow glass microspheres:

1) Density can be decreased to as low as 0.90g/cm³

2) Low porosity

3) High compressive strength

4) Good stability at high temperature and pressure

5) Low fluid loss rate

6) Adjustable thickening time
