Product Description

Solid (Graphite lubricant)Lubricant

Performance and Function: The solid lubricant is made from high-quality 
graphite powder modified and activated by various surfactants, exhibiting a high reduction rate in coefficient of friction. This product can strengthen the wellbore, lubricate the drill string, prevent collapse, and increase drilling speed. It has excellent lubricity, temporary plugging, and temperature resistance, and it is compatible with drilling fluids without adverse effects on their performance. It is non-toxic, non-polluting, and has the additional ability to reduce the fluid loss of drilling fluids, seal leaking formations, and can be used in drilling fluids within a wide density range.
Performance Characteristics
1. Lamellar crystalline structure (layered structure)
2. Good high-temperature resistance,Adjustable size range
3. Chemically inert and highly compatible
Product application:Oil and gas drilling fluids

Main Functions

1. Significantly Reduces Friction Coefficient (Drag & Torque Reduction)

Effectively reduces drill string torque and friction, minimizing the risk of stuck pipe.

Generally, friction can be reduced by 20-40%, depending on the system.

2. Improves Wellbore Quality and Reduces Adhesion

The graphite lubricating film reduces the adhesion between the drill string and the wellbore.Especially effective in preventing stuck pipe adhesion in shale wells, horizontal wells, and long open-hole wells.

3. Stable Performance in High-Temperature Wells

Not easily oxidized or decomposed under high-temperature (HPHT) conditions.

Suitable for high-temperature drilling systems such as deep wells, ultra-deep wells, and geothermal wells.

4. Minimal Impact on Drilling Fluid Properties

Does not affect key parameters of the drilling fluid such as density, rheology, and filtration loss.

Especially refined graphite products offer better dispersibility and do not increase plastic viscosity.

5. Good Environmental Friendliness

Graphite is a natural mineral, environmentally friendly and pollution-free.

It can be used for drilling in environmentally sensitive areas (such as freshwater and marine areas).

6. Forms a durable mechanical lubricating film

Graphite forms a thin "dry lubrication" layer on the wellbore and drill string surfaces, improving mechanical transmission efficiency.

It provides good protection for drill pipe threads, directional tools, and drilling instruments.

7. Can be used in conjunction with oil-based lubricants

The lubrication performance is further enhanced when graphite is combined with oil-based lubricants (esters, fatty alcohols, etc.) (some combinations can achieve a friction reduction of over 50%).

Typical Application Scenarios

As an auxiliary lubricant when water-based drilling fluids have high friction.

Horizontal wells, directional wells, long-reach wells

Formations prone to sticking in open-hole sections (shale, sandstone, etc.)

Ultra-deep wells, high-temperature wells, high-angle wells

Replacing oil-based agents in projects with high environmental protection requirements.
