有机硅抑制剂其主要组分为叫做硅油有机硅成分，硅油常温下是不挥发的油状液体，在水、动植物油及矿物油中不溶，或溶解度很小，既能耐高温，也能耐低温。化学性能惰性，物理性性能稳定，无生物活性。本品能抑制泥页岩的水化分散，起到稳固井壁的作用。
       本产品为油田化学品，主要由有机硅单体等化工原料多次分段聚合反应而成，无毒、无害。使泥浆具有憎水的毛细作用，有效地防止泥页岩的膨胀，改善泥饼摩阻，降低粘土颗粒之间的相互作用，具有稀释效应，体现了有机硅化合物具有的一贯优点，是石油钻井广泛使用的泥浆助剂。
       Silicone inhibitor its main component is called silicone oil silicone composition, silicone oil at room temperature is not volatile oily liquid, in water, animal and vegetable oils and mineral oil, insoluble, or very small solubility, both high temperature and low temperature. The chemical property is inert, the physical property is stable, and has no biological activity.
       This product can inhibit the hydration of shale dispersion, play a stable role in the borehole. This product is oil field chemical, mainly by organic silicon monomer and other chemical raw materials multi-stage polymerization, non-toxic, harmless. So that the mud has hydrophobic capillarity, effectively prevent the expansion of mud shale, improve mud cake friction, reduce the interaction between clay particles, with dilution effect, reflecting the consistent advantages of organosilicon compounds, it is a mud additive widely used in oil drilling.
