套管磨损估计
摘要：
套管磨损估计。说明性实施方案中的至少一些是包括以下项的方法：计算指示钻井操作的静止套管磨损的值，所述静止套管磨损是通过钻柱抵着套管的内径的相互作用而引起；计算指示所述钻井操作的冲击套管磨损的值，所述冲击套管磨损是通过所述钻柱抵着套管的所述内径的相互作用而引起；和组合指示静止套管磨损的所述值和指示冲击套管磨损的所述值以确定指示总计套管磨损的值。
摘要（英）：

The invention relates to casing wear estimation. At least some of the illustrative embodiments are methods including: calculating a value indicative of static casing wear of the drilling operation, the static casing wear caused by interaction of a drill string against an inside diameter of a casing; calculating a value indicative of impact casing wear of the drilling operation, the impact casing wear caused by interaction of the drill string against the inside diameter of a casing; and combining the value indicative of static casing wear and the value indicative of impact casing wear to determine the value indicative of aggregate casing wear.
