PDC 钻头作为一种高效破岩工具，在石油工业中的应用越来越广泛。复合片的磨损直接影响着钻头的钻速和使用寿命。在目前研究的基础上，分析了 PDC 钻头复合片研磨性磨损、热磨损和冲击磨损三种磨损形式的磨损机理；研究了钻井参数、地层特性及复合片自身结构性能参数对复合片磨损的影响规律。建立了一个比较完善的复合片磨损速度模型，为进一步的研究提供了理论依据。

PDC bit,as an effective tool for breaking rocks,is applied in a wider range of oil industry.The composite cutter wear will directly affect drilling rate and service life of the PDC bit.Based on the current research,the paper analy-zes three wear mechanism including abrasive wear,thermal wear,and shock wear,and discusses the impact of drilling pa-rameters,formation characteristics and intrinsic structural performance on wears.A better swear rate model of PDC compos-ite cutters is established to provide the theoretical foundation for further study.
