摘　　要：指重表是钻井工程中的常用仪器仪表,在整个钻井工程中占有不可替代的位置,发挥着及其重要的作用。然而,钻井指重表作为仪表类设备,它内部构件的强度是有限的,且作为指示类仪表,钻井指重表的精确度直接关系到操作人员是否能对井下情况做出准确判断。所以钻井指重表的日常维护和保养工作就成了井队施工作业过程中的重要一环。Weight indicator is a common instrument in drilling engineering, and it＇s occupies an irreplaceable position in the whole drilling engineering. However, as a instrument equipment, the strength of the internal component in the weight indicator is limited and as a indicating instrument, the accuracy is directly influence the judgment of the operating personnel. Thus, the daily maintenance of weight indicator is an important ring of the operation of the well drilling team.
