Low Fluorescence Shale Inhibitor White Asphalt For Drilling Fluid (environmental Protection Type)
White asphalt is a product of fatty alcohol resin after water-soluble processing. It can emulsify with water and clay. Prevent formation collapse and protect oil and gas layers. Compared with asphalt, it has low fluorescence and will not interfere with geological logging. The application in complex formations shows that the low-fluorescence anti-slump agent has the function of reducing high-temperature and high-pressure fluid loss, is resistant to temperature, and can prevent the collapse of hard and brittle mud shale and inorganic salt formations. Degradable, non-toxic, and an environmentally friendly drilling fluid additive.
Our white asphalt is refined from non-fluorescent oil-soluble substances and surfactants through a special process. This product not only has the excellent plugging and anti-collapse performance of asphalt products, but also is non-toxic, low-fluorescence, non-polluting to the environment, and protects the environment. For oil and gas formations, it can be directly added to various water-based drilling and completion fluids, and the general dosage is 1%-3%.
