I.Properties and specificity

HR glass beads solid drilling fluid lubricant has suitable hardness, strength, density and granule size distribution, according to the requirement of the job site, the granule size of this product can be adjusted, through the suspension property, the glass beads are uniformly dispersed or adsorbed on the wall surface of the whole annular space, countless coil rolls are formed between the drilling tools and the walls, turning the sliding friction into rolling friction.
The main characteristics and purposes of this product:
1.Can effectively improve the lubricity of drilling fluids, reduce the torque of drilling tools and prevent the occurrence of sticking accidents.
2.Temperature resistance is the best (not less than500℃), suitable for large angle inclined wells, horizontal wells, complex wells, deep wells and exploration wells.
3.The surface of this product is smooth, when friction with other materials plays the role of automatic lubrication.
4.The balls themselves have suitable strength, can take on a lot of pressure.
5.Its skinned density is adjustable, and is suitable for different areas of the trunk.
6.Due to the abnormality of the walls and the incompatibility of the balls, uniform and smooth walls are formed.
7. Does not fluoresce, which facilitates identification and detection of oil and gas reservoirs.
8.The technology of using in the field is simple, can directly add them into the drilling mud, and the care and operation are simple.

II. Technical indicators

Technical requirements of the product "Solid lubricant for drilling mud-glass balls"

Ⅲ. Method of use

According to the actual situation in the wells by proportion to add this product into the drilling mud, by high-speed rotation to hammer them into the walls, and can greatly reduce or decrease the friction obstacle coefficient. According to the diameters of vibrating screen mesh select glass balls, which can freely pass the vibrating screen, add by proportion into the drilling mud, play the accompanying lubricating role, thus lubricate the walls。

1.When lowering the case, glass balls of 2-0.9 mm can be used to prevent the case from jamming;
2.Glass spheres of 0.9-0.2mm diameter can solve the problem of depressurisation when drilling directional and horizontal wells, cable jamming during electrical testing and are usually used in the middle of drilling and closing the well to improve mud lubrication。
