钻井液被认为是任何钻探活动的支柱。因此，这一要素的适当配方是任何成功钻井作业的关键因素。如果做不到这一点，将导致灾难性的事件，如井涌、漏失、井喷，甚至放弃油井。在本研究中，配制了一种水基钻井液(WBDF)，并对其滤失性能进行了测试。其次，对加入1个纳米颗粒和2个聚合物后的泥浆体系进行了2^n析因敏感性分析。这些添加剂是纳米颗粒、氧化石墨烯和聚合物、纯孔和海藻酸钠，在泥浆体系中以不同的浓度使用。在实验室内进行了加入颗粒后的8次实验运行，统计分析了颗粒浓度对滤失量的影响。结果表明，这两种聚合物在控制滤失量方面都起到了重要作用。聚合物浓度的增加减少了泥浆体系的滤失量。这些聚合物堵塞了滤纸上的毛孔，最终减少了滤液量。另一方面，GO浓度在本研究中并不显著。在较高浓度下，GO形成团聚，这对降滤失量没有显著影响。然而，当GO与聚合物一起使用时，其性能会提高。建立了减少滤液体积的渗透界面。此外，聚合物之间的相互作用也不是很大。这两种聚合物相互缠绕在一起，降低了它们对过滤损失的影响。所有这些分析都有助于设计更大规模的泥浆系统。全析因设计在泥浆体系配方中的应用大大减少了总体工程成本、时间和实验次数。
Drilling fluid is considered to be the backbone of any drilling activity. Therefore, proper formulation of this element is the key factor for any successful drilling operations. Failure to do so will result in catastrophic events such as kick, loss circulation, blowout, or even abandonment of the well. During this study, a water-based drilling fluid (WBDF) was formulated and was tested for filtration properties. Next a 2^ n factorial sensitivity analysis was executed on the mud systems after the addition of one nanoparticle and two polymers. These additives were nanoparticles graphene oxide and polymers pure-bore and sodium alginate that were used in varying concentration in the mud system. A total of 8 experimental runs after the addition of the particles were conducted in the laboratory, and the influence of the particle concentration on the filtrate loss volume was statistically examined. It was observed that both the polymers played a significant role in controlling the loss of filtrate volume. An increase in concentrations of the polymers reduces the loss of filtrate volume from the mud system. These polymers block the pores in the filter paper, which eventually decreases the filtrate volume. On the other hand, GO concentration was not significant in this study. At higher concentration, GO forms agglomeration; this had no significant influence on the filtrate reduction. However, when GO is used in conjunction with polymers, its performance increases. An infiltrate interphase is established that reduces the filtrate volume. Additionally, the interaction between the polymers was also not substantial. Both polymers tangled around one another and decrease their impact on filtration loss. All these analysis helped in designing the mud system on larger scale. The application of full factorial design in formulation of the mud system drastically reduces the overall project cost, time, and number of runs of experiment.
