First, the use of products
Low fluorescent solid lubricant is a kind of low fluorescent and high efficient lubricant, which is made of natural graphite as the main raw material, with appropriate coating agent and surface active agent. It can effectively reduce the friction between drill pipe and borehole wall, drill pipe and casing pipe, drill pipe and mud in the process of drilling. Lubrication is especially suitable for horizontal wells, large displacement wells, wells and wells of some difficult window. Graphite has special layered structure itself has a good lubrication, this as basic materials, together with the appropriate fatty acid and glyceride and surface active agent, through a certain process treatment, increase the lubricity of graphite, its performance was better play.

Two, technical requirements

Three, the use of methods
This product can be directly added to a variety of water-based drilling fluid, completion fluid, the general increase of 1% ~ 1.5%.

Four, storage and transportation
1 products are stored in a dry and ventilated place, avoid direct sunlight and rain.
2 transport and handling should be handled gently. To prevent damage to the packing, transportation should be covered.

Five, matters needing attention
In the use of the process, the staff should wear a dust mask, wear chemical safety glasses, wear anti-static work clothes. Avoid producing dust. Prevent products from entering the eyes or in contact with the skin, once the occurrence of the above situation, with water or saline flush, the situation is serious and timely medical treatment.
