1. Product introduction
This product is a kind of yellowish brown solid or powder with high hardness, acid and alkali resistance and immersion resistance. It will not carbonize at high temperature after film forming to protect its special performance. It can significantly reduce the filtration of drilling fluid without affecting the rheological properties of drilling fluid, has excellent temperature resistance, is not affected by electrolyte pollution, and is non-toxic and harmless.
Due to the difference of particle size, plugging should be used for leakage of different formations. It can be used alone or in conjunction with other granular materials and active gel materials. It is an indispensable plugging material for drilling operations.
