智能流体作为一种物理性能“可控”的智能材料，在航天、生物、医疗以及微电子等行业得到了广泛应用。根据智能流体响应条件，将智能流体分为了外场可控智能流体(以磁流变流体和电流变流体为代表)和刺激响应可控智能流体(以智能水凝胶为代表)，系统总结了智能流体的流变机理、研究现状，指出将纳米材料引入智能流体是目前研究热点。在此基础上，介绍了可应用于钻井液中的智能流体室内研究进展，分析了智能流体应用于钻井液的可行性。最后结合智慧油田发展需求，提出了开发智能钻井液、研发智能钻井设备以及智能钻井液操控系统是未来智能钻井发展新方向。

Intelligent fluid, as a smart material with “controllable” physical properties, has extensive industrial applications in aerospace, bio-engineering, the medical industry, and micro-electronics. By response conditions, intelligent fluids were divided into the external-field controllable intelligent fluid (represented by magneto- and electro- rheological fluids) and stimuli-driven controllable intelligent fluid (represented by the smart hydrogel). The rheological mechanism and research progress of intelligent fluids were systematically reviewed and it was pointed out that the current hot spot of relevant research is to introduce nano-materials into intelligent fluids. Furthermore, the laboratory research progress of intelligent fluids applicable to drilling fluids was summarized to demonstrate the feasibility of intelligent fluids as drilling fluids. At last, given the development requirement of smart oilfields, it was proposed that inventing intelligent drilling fluids and developing smart drilling equipment, in particular, smart drilling fluid operation systems, are the development orientations of future smart drilling.
