Organosilicon Deformer PD-100, as an effective deformer, is refined from organ silicon agent, dispersing agent and various active agents after high temperature. It has a strong adhesive property, and deforms by forming new liquid film on the surface of foam. PD-100 is used for eliminating foam existed in all kinds of water-based drilling fluids. It can be added to all kinds of water-based drilling fluids.
Defoamer is a kind of polyether additive. It has good properties of foam breaking and anti-foaming property. Defoamer is a liquid defoaming agent to control foaming in all water-based drilling fluid including freshwater, seawater, saltwater, and saturated saltwater, as well as completion fluids.
