有机硅降粘剂不仅具有优良的降粘特性，而且还具有一定的护壁防塌功能，对钻井液体系有分散、润滑、消泡等作用，并可消除钻井过程中钻井液侵入地层引起的泥页岩水化膨胀以提高井壁的稳定性，钻井液处理后维护期长，是一种无毒、无污染的环保型产品，可直接加入各种水基钻井完井液，一般加量为0.5%~2%。
       Silicone viscosity reducer has not only excellent viscosity reducing function, but also has some anti-collapse function. It has functions of dispersion, lubrication, defoaming, and can reduce the mud invasion during drilling, and inhibit formation shale hydration and expansion, which can improve the stability of the wellbore. It can maintain a long stable period after mud treatment. It is a non-toxic, pollution-free and environment-friendly products. It can be directly added to a variety of water-based drilling and completion fluids. The dosage is generally 0.5% to 2%.
