Application of hollow glass microspheres in the exploitation of oil and gas fields
Appearance: White fine powde
Particle shape: Hollow spheres 
Composition: Soda lime borosilicate quality
True density: 0.20-0.60g/cm³
Average particle size: about 2-120μm
Compressive strength: about 4-69MPa
Thermal conductivity: 0.03-0.06w/m.k
1.Hollow glass ball itself is inert without pollution. As a continuous medium, low density drilling fluid with addition of hollow glass microspheres was incompressible, and all wells are
uniform in density. Sludge cakes formed have good lubrication, reducing the risk of sticking. It is technically infeasible for drilling large deviated wells and horizontal wells since the
recycled micro-foam and air drilling technology can not deliver MWD signal. However, hollow glass microspheres have an irreplaceable advantage for it can not affect the system signal.
2.Hollow glass microspheres has a good rolling performance, and it can increase the drilling rate, and significantly improve the drilling efficiency.
3.Drilling fluid with hollow glass microspheres has feature of high temperature resistance, high pressure resistance, stability, durability, and can be recycled.
4.With the increase of low middle pressure layer, low-density slurry cementing with hollow glass microspheres were adopted to consolidate the wells to prevent or reduce leakage, increase the cement top. It plays a significant role in increasing the exploration reserves, improving single well production, and effectively developing underground oil and gas resources so as to solve complex problems.
Application in the oil drilling fluid
1）Obvious effects on reduce the density,wide range of adjustable density,to prevent the formation breakdown,reservoir protection,enhanced oil recovery.
2）Good stability at high pressure and high temperature.
3）Good lubricity, Reduce drilling tool wear and enhance drilling speed.
4) Mud cake quality improved.
5) Good compatibility, no influence on rheological parameter.
6) No damage on the reservoir.
7) No loss of MWD signal.
8) Simple to use、easy pump、recyclable, low cost on equipment.
Application in the well cementing slurries
1)Obvious effects on reduce the density,wide range of adjustable density,to prevent the formation breakdown,reservoir protection.
2)High crush strength, good stability under high pressure and high temperature.
3)Low water loss rate.
4)Adjustable thickening time, a right Angle thickening.
5)Good rheological characteristic.
6)High filling rate.
Sealed oil and gas layers, excellent performance on anti gas channeling properties.
