First, the use of products
Because the product contains sulfonic acid group, hydration is very strong, when the adsorption on the shale interface, can prevent the hydration of shale particles dispersed to play the role of anti collapse. At the same time, it is not soluble in water and can fill the pores and cracks, and can cover the shale interface, improve the quality of mud cake. In the drilling fluid also play a role of lubrication and reduce the high temperature and high pressure filtration is a kind of plugging, anti sloughing, lubrication, reducing resistance, inhibition of multifunctional drilling fluid treating agent, can reduce the drilling tool lifting capacity and torque, extends bit period, to prevent and relieve sticking and formation of thin and tenacity of mud cake reinforced wall. Control the high temperature water loss, control the high temperature shear strength of mud; can be used in combination with other mud treatment agent.

Three, the use of methods
Recommended dosage 1-6%.

Four, storage and transportation
1 products are stored in a dry and ventilated place, avoid direct sunlight and rain, away from fire, kept separate from acid.

2 transport and handling should be light light unloading, packaging to prevent breakage. Transport should be covered.

five, matters needing attention
1 avoid contact with acids.
2 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.
