Abstract

Drilling is a crucial operation in mining and construction, and optimizing it can significantly impact costs and operation time. Therefore, it is necessary to determine the parameters affecting the drilling and the correct understanding of these relationships can help to optimize the drilling operation. In the meantime, the relationships between the parameters of the drilling machine and the rock can be considered as a decisive operational condition. One of the effective parameters in drilling is the rock texture, which is measured based on the image analysis of thin sections. Additionally, the vibration caused by drilling can assist in determining the type of rock and its characteristics, guiding further operations. In this study, we utilized a laboratory-scale drilling machine to measure the vibration it caused during drilling and examined its relationship with the microfabric parameters of 10 different rocks. Statistical analysis indicated the highest and lowest correlation coefficient between vibration with aspect ratio and the equivalent diameter, respectively. These relationships can provide a good view of the impact of rock texture parameters on the vibration of the drilling rig on a laboratory scale. Also, by using the 3D surface plot and considering the combination of rock microfabric parameters, the drilling vibration can be predicted with much higher accuracy. This result shows that the drilling vibration is affected by a combination of rock microfabric parameters.

岩石微组构参数对钻机振动影响的室内研究

钻井是采矿和建设中的关键作业，优化钻井可以显著影响成本和作业时间。因此，有必要确定影响钻井的参数，正确认识这些关系有助于优化钻井作业。同时，钻机参数与岩石之间的关系可以被认为是一个决定性的运行条件。岩石纹理是钻井中的有效参数之一，它是基于薄片图像分析来测量的。此外，钻井产生的振动可以帮助确定岩石的类型及其特征，指导进一步的作业。在这项研究中，我们利用实验室规模的钻孔机测量了它在钻孔过程中引起的振动，并研究了它与10种不同岩石的微组构参数的关系。统计分析表明，振动与长径比和等效直径的相关系数分别最高和最低。这些关系可以在实验室规模上很好地了解岩石结构参数对钻机振动的影响。此外，利用三维曲面图，结合岩石微组构参数，可以提高钻井振动的预测精度。结果表明，岩石微组构参数的组合对钻井振动产生影响。

期刊介绍： Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces: • the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations; • the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change; • the assessment of the mechanical and hydrological behaviour of soil and rock masses; • the prediction of changes to the above properties with time; • the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
