摘　　要：针对三维抗钻特性参数难以确定的问题,基于岩性特征优选了适合顺北地区的抗钻特性参数预测模型.通过对测井资料的分析和计算,获取了22口井的抗钻特性参数.根据井位和地层信息建立了三维几何模型,通过赋值、井的粗化以及纵横向高斯插值得到三维抗钻特性参数模型.结合现场需求得到了新近系—奥陶系的抗钻特性参数纵向分布规律,以及二叠系地层的横向分布规律.研究结果显示,二叠系中浅地层的研磨性较小,而二叠系以下的地层研磨性显著增加.从新近系到奥陶系,岩石抗钻特性参数呈增加趋势,其中,古近系和二叠系地层相较于相邻地层具有更大的抗钻特性参数,同时表现出较为明显的软硬交错.在顺北地区,二叠系北部地层的抗钻特性整体上高于南部地层,而东西部之间的抗钻特性参数差异并不明显.建立的三维岩石抗钻特性参数模型为进一步研究提供了基础,应用二叠系和石炭系—志留系地层抗钻特性的预测结果进行钻头选型和钻井参数的优化,二叠系和石炭系—志留系的机械钻速分别提高了53.80%和35.10%.该方法不仅有效提高了钻头与目标地层的匹配程度,而且为顺北地区的钻井提速提供了重要的理论依据.Based on the characteristics such as lithology,a predictive model for anti-drilling characteristic parameters suitable for the Shunbei block was selected.By analyzing and calculating logging data,anti-drilling characteristic parameters for 22 wells were successfully obtained.Subsequently,a three-dimensional geometric model was established based on well locations and stratigraphic information,and a three-dimensional anti-drilling characteristic parameter model was obtained through assignment,well roughening,and longitudinal and transverse Gaussian interpolation.A detailed analysis based on the model revealed the longitudinal distribution characteristics of anti-drilling characteristic parameters from the Neogene to Ordovician and the lateral distribution characteristics of Permian strata.The results showed that the abrasiveness of shallow layers in the Permian is relatively low,while the abrasiveness of layers below the Permian significantly increases.From the Neogene to the Ordovician,the anti-drilling characteristic parameters of rocks show an increasing trend,with the Permian and Neogene strata having larger anti-drilling characteristic parameters compared to adjacent strata,and showing a more obvious alternation between soft and hard layers.In the Shunbei block,the overall anti-drilling characteristic parameters of northern Permian strata are higher than those of southern strata,while the difference in anti-drilling characteristic parameters between eastern and western parts is not significant.The successfully established three-dimensional rock anti-drilling characteristic parameter model provides a basis for further research.Finally,the predicted results of anti-drilling characteristic parameters for Permian and Carboniferous-Silurian formations were applied to optimize drilling bit selection and drilling parameters,The mechanical drilling rate(ROP)in the Permian formations increased by 53.80%,and that in the Carboniferous-Silurian formations increased by 35.10%.This method not only effectively improves the m
