该文通过结合机械比能理论和钻速方程提出了一种新的钻头磨损监测方法，该方法综合考虑了机械比能模型和钻速方程模型，能有效地确定钻头在井下的磨损状况。该文通过中石化国际工程有限公司在阿尔及利亚打钻的MKT-1井进行了钻头磨损分级的计算，计算结果与实测数据基本一致，证明该方法的科学性，对提高钻井效率具有一定的指导意义。

China deploys its oil exploration and development so widely that the safety risk from quality gets higher,contradictions caused by fast growth looms larger,and quality control becomes more difficult.Therefore,how to take special advantages of ideological and political work of state-owned petroleum enterprise and how to improve business quality management are the new issues for its quality controllers to explore.This paper presents broadly relations between business quality control and ideological and political work,analyzes the current dilemma the management is facing and puts forth the management idea in line with innovative ideological and political work.
