First, the use of products
The composite plugging agent KD-68 is mainly composed of plant hard shell, mica and plant fiber. Suitable for drilling holes, large pores, porous formation of plugging, reduce the loss of formation. The sealing effect is good, the compatibility is good, and the performance of the slurry is not affected.

Three, the use of methods
This product can be directly added to various water-based drilling fluid system, used to block the formation of cracks, to prevent leakage of drilling fluid, while protecting oil and gas reservoirs. The general dosage is 3 ~ 5%.

Four, storage and transportation
1 products are stored in a dry and ventilated place, prevent rain, no direct sunlight, away from fire and heat.
2 transport and handling should be handled gently. To prevent damage to the packing, transportation should be covered.

Five, matters needing attention
