One of the inevitable problems encountered during the petroleum well drilling process is "lost circulation" in which part of the drilling fluid is lost into the formation. A combination of nanoparticles with their unique properties and cost-effective biodegradable materials can play an effective role in treating fluid loss. In this study, our aim was to formulate drilling fluids modified with nanoparticles, pomegranate peel powder, and plant powder. The drilling fluids were identified and recognized using scanning electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy techniques. Furthermore, experimental tests were conducted in order to investigate the performance of the newly formulated drilling fluid in improving fluid loss characteristics. The obtaining results have shown that adding 0.3 wt % of pomegranate peel powder to the reference (base) drilling fluid reduces the filter loss volume to 7.9 mL compared to the reference fluid (11.6 mL). As the optimal concentration of TiO was mixed with 0.3 wt % of pomegranate peel powder then added to the reference fluid, the filter loss volume was reduced to 8.6 mL.
石油钻井过程中不可避免会遇到的问题之一是“漏失循环”，即部分钻井液漏入地层。具有独特性能的纳米颗粒与经济高效的可生物降解材料相结合，可在处理滤失方面发挥有效作用。在本研究中，我们的目标是配制用纳米颗粒、石榴皮粉和植物粉改性的钻井液。使用扫描电子显微镜、X射线衍射和傅里叶变换红外光谱技术对钻井液进行识别和表征。此外，还进行了实验测试，以研究新配制的钻井液在改善滤失特性方面的性能。所得结果表明，与参考（基础）钻井液（11.6 mL）相比，向参考钻井液中添加0.3 wt%的石榴皮粉可将滤失量降低至7.9 mL。当将最佳浓度的TiO与0.3 wt%的石榴皮粉混合后添加到参考流体中时，滤失量降低至8.6 mL。
