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.
