Plugging Agent While Drilling

Plugging Agent While Drilling

Plugging agent while drilling is a special additive used to prevent leakage in drilling fluid. During the drilling process, due to the continuous rotation of the drill to cut the formation, the surrounding earth and stone will be squeezed into the drilling hole by liquid pressure, resulting in a drop in the mud level, resulting in leakage. When the drilling plugging agent is added to the drilling fluid, it can prevent soil and rock penetration, improve the density of drilling fluid, and avoid leakage .

The drilling plugging agent used in oil-based drilling fluid has a good effect of reducing filtration, can form a dense mud cake in the well wall to prevent the occurrence of permeability loss, and can effectively prevent the recurrence of leakage of plugging materials and induce cracks during the process of tripping.
