1. Product introduction
The main component of this product is borosilicate, a hollow sphere with particle size of 10-250 microns and wall thickness of 1-2 microns. The product has the advantages of light weight, low thermal conductivity, high strength and good chemical stability.
It is mainly used as a lubricant in oil drilling fluid, which can improve the lubricity of all types of drilling fluid, reduce torque and friction, prevent differential pressure sticking, and especially change the lubricity of horizontal wells.
