渤海油田储层黏土含量高,钻井过程中造浆严重,导致钻井液流变性控制较为困难,通过室内实验研究优选出胺基硅醇抑制剂,并对胺基硅醇的作用机理及JFC钻井液的作用原理进行了系统的实验分析。实验结果表明,现有的JFC钻井液体系加入胺基硅醇后具有良好的疏水性，能够有效抑制黏土水化造浆，可以容纳较高含量的黏土矿物,并在应用过程中不会出现黏度上升和滤失量上涨等问题,对其流变性和滤失性影响不大。实验结果对于井壁稳定和储层保护具有参考意义。
The high content of clay in Bohai Oilfield reservoir and the serious mud-making in drilling process make it difficult to control the rheology of drilling fluid.The amidocyanogen silicone inhibitor is optimized through laboratory experiments, and the mechanisms of amidocyanogen silicone and effect on JFC drilling fluid principle are analyzed by a series of experiments.The experimental results show that the existing JFC drilling fluid added with amidocyanogen silicone has good hydrophobicity,which can effectively inhibit the clay hydration slurry, and improve clay mineral tolerance.In the process of application, there will be no issues such as the rise of viscosity and the increase of filtration loss.So, it has little effect on its rheological property and filtration property. The results provide reference for wellbore stability and reservoir protection.
