Manufacturer for Hollow Glass Microsphere - Glass Bubbles as a Density Reducing Agent in an Oil Base Drilling Fluid for MarginalLow-Permeability Low Pressure Reservoirs – Kehui

Hollow glass spheres, also known as glass bubbles, as a density reducing agent in a drilling fluid. In the field application, a proprietary oil-in-water emulsion fluid which contained hollow glass bubbles was used during the drilling of a producing interval. The oil-in-water emulsion provided a suitable fluid base, whereas the glass bubbles, by virtue of their low density, imparted a lower finished density than that of the corresponding base fluid. The density lowering capacity of the glass bubbles is proportional to the concentration of bubbles incorporated in the fluid.

In the field application, the fluid-glass bubble pair is stable, homogenous, and compatible through conventional mud motors, bits, surface cleaning equipment, and of such rheological and filtrate properties, as to lend itself to be used in low pressure reservoirs and in producing zones of high permeability.
Glass beads spherical structure, which has high hardness, smooth surface, such as features, rolling performance is good. Use it as drilling fluid additives, can play a role similar to the bearing in the ball, greatly reduce the frictional resistance of drill pipe, drilling fluid, fast bit drilling, improve the rate of penetration, and reduce the bit wear.
Now, in the exploration and development is difficult, purpose layer under the condition of buried depth, low formation pressure with application of glass beads in underbalance drilling has many advantages, one of the biggest advantages is the glass beads can improve drilling speed; From the shaft to the differential fluid pressure of formation fluid in the range of 0 ~ 6.9 Mpa, the common drilling method in sandstone, limestone, shale drilling efficiency would lower 70 ~ 80%, and the glass beads can reduce wellbore pressure significantly improve drilling efficiency.
