摘　　要：钻井液固相控制是钻井液处理的主要工作,传统固控设备对于200目以下的超细岩粉处理效果并不明显。受到电吸附技术在污水处理广泛应用的启发,通过对实验室配置的含砂率4%的无固相钻井液在不添加化学处理剂的情况下,进行单因素影响吸附实验,分析吸附时间、吸附电压、电极板间距以及钻井液黏度对吸附效果影响的规律,得到最佳吸附参数:吸附时间为15min,吸附电压为36v,电极板间距为5cm,达到高效经济地清除钻井液中超细岩粉的效果,为后续科学设计金刚石钻进超细岩粉吸附器提供了借鉴。Drilling fluid solid phase control is the main task of drilling fluid treatment.Traditional solid control equipment has no obvious effect on ultrafine rock powder under 200 mesh.Inspired by the widespread application of electroadsorption technology in sewage treatment,the laboratory is equipped with a solid-free drilling fluid with a sand content of 4%and without the addition of chemical treatment agents for this study in order to conduct adsorption experiment with a single-factor influence and analyze the influence of time,voltage,electrode spacing and drilling fluid viscosity on the adsorption.The results indicate the optimal adsorption parameters such as adsorption time of 15 min,adsorption voltage of 36 v and distance between electrodes of 5 cm.
