摘　　要：针对塔中地区深井构造特征,利用综合资料法(包括地震、测井、钻井和实验室资料等)进行地层抗钻特性评价、岩性预测和地层可钻性剖面的研究,得出地层的抗压强度、抗剪强度、硬度、研磨性、牙轮和PDC钻头的可钻性级值等力学参数,建立塔中Ⅰ号断裂带可钻性剖面。对101口井实钻钻头使用情况进行分析,结合地层可钻性剖面优选钻头类型。现场试验取得良好效果,证明该措施经济实用,能够有效提高深井机械钻速。On the basis of characteristics of deep logs in TaZhong Area,the method of integrated information（including seismic,logging,drilling and laboratory information,etc.） is taken to study anti-drilling of formation,rock properties and drillability sections,and the mechanical parameters such as compressive strength,shear strength,hardness,abrasive,roller cone and drill-level of PDC bit are obtained,and drillability sections of the fault in Tower I are established.In this paper,a measure that the bit types are determined in combined with drillability sections is presented by analyzing practical log data in 101 wells,good field test results proves that the measure is economical and can improve the ROP in drilling deep wells.
