Product Description

Filler Bubbles Hollow Glass Microspheres used in oilfield exploration


Description of hollow glass microspheres:


Hollow glass microspheres is pure white powders, which is hollow and transparent spheres under the microscope, hollow and contain thin air.

With a smooth surface of micron scale. The main component is borosilicate. It is known as the "21st century space material", it brings innovative

application solutions to cost reduction and efficiency increase in production and manufacturing for many industries.


The most wide application of hollow glass microspheres is as a filler for Low density drilling fluid and cementing cement in oilfields exploration.

Application of hollow glass microspheres


Application of Hollow Glass Sphere in Low Density Drilling Fluid and Cementing Slurry

Because of low density and high compressive strength, Hollow Glass Sphere is very suitable in preparing low-density drilling fluids. It is widely used in deep oil wells to keep the constant stability of the density of drilling fluids;

Round spherical shape, very good fluidity, perfect lubrication function, these characteristics of Hollow Glass Sphere can reduce friction during drilling process, extend the service life of drill pipes and drill bits, and greatly improve drilling effect as well as drilling performance;


The low-density and high-strength slurry system prepared by Hollow Glass Sphere is one of the main ways to resolve the low pressure and the loss of cementing slurry which is easy to leak.
