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

The advantages of low density drilling fluid prepared by hollow glass beads:

● Hollow Glass Sphere are inorganic non-metallic oxides, which are weakly alkaline and very stable in nature. They can be added to various existing mud systems without reacting with various chemicals in the mud, which can ensure the chemical stability of drilling fluid;

● Low density, high compressive strength, easy to deploy low density drilling fluid, can be widely used in deep wells, to ensure the stability of drilling fluid density;

● Spherical, excellent fluidity, excellent lubrication, can reduce friction in the drilling process, can extend the service life of drill pipe and drill bit and other equipment, can greatly improve the drilling speed, improve operation efficiency;

● The particle size state is easy to use with existing drilling equipment, no need to add special equipment, and the Hollow Glass Sphere in the drilling fluid can be recycled and reused, reducing production costs;

The low density and high strength slurry system prepared by adding hollow glass microspheres is one of the main ways to solve the low leakage and low return of cement slurry in low pressure and easy leakage wells. Advantages of cementing slurry prepared by Hollow Glass Sphere:

● Excellent fluidity, easy to mix and pump;

● Inorganic composition, high temperature resistance and high pressure resistance make the mud performance stable;

● The thickening time can be adjusted according to the construction needs, which is convenient for operation;

● Effectively control the water loss rate and prevent pollution;

● The density of the slurry is low, the compressive strength is high, and the 24h compressive strength can reach more than 14MPa;

● Improve cementing quality and prolong oil well life;
