During the drilling process,due to the effect of pressure difference,the water in the drilling fluid will inevitably filter through the well wall into the ormation,causing the drilling fluid to lose water.This series of products is added to the drilling fluid to make the clay particles adhere to the well wall to form a "filter cake",which not only prevents the further loss of water in the
drilling fluid,but also protects the well wall.It is an important mud treatment agent to stabilize the well wall and ensure the regularity of the well diameter.
