过去采用精密的资料采集系统已经对地面钻井数据进行了监测和采集,但是随着这种系统的改进,详细地研究各项钻井参数,已经证明了地面监测能够对正在钻进的岩层提供精确的评价。本文检验并阐明了地层孔隙度、孔隙压力、岩性、胶结强度和其他岩石物性的各种不同解释与抗钻强度的关系。在井场,为了提高地面评价的能力和提供所需要的资料,已经采用了小型计算机,终 Ground drilling data has been monitored and acquired using sophisticated data acquisition systems in the past, but as such systems have been refined, detailed studies of various drilling parameters have proven that surface monitoring can provide accurate Evaluation. This paper examines and clarifies the relationships between the various interpretations of formation porosity, pore pressure, lithology, cementation strength, and other petrophysical properties and the resistance to drilling. In the well site, in order to improve the capacity of ground evaluation and provide the required information, a small computer has been used,
