摘　　要：为了解胜利油田坨 2 1断块套管损坏情况 ,利用方位井径、超声成像、声波变密度等测井技术对套管技术状况进行了监测 ,并对该断块套损成因进行了初步探讨 ,总结出该断块套管损坏的原因主要为断层影响、注采不平衡及腐蚀。在取得正确认识的基础上 ,对所监测井采取了相应措施 ,取得了一定的效果 ,确立了该类断块油田套管技术状况监测的手段及方法。Azimuth caliperlog, supersonic imaging log and sonic variable density log are used in inspecting the casing status to know the casing damages in Tuo-21 Block, Shengtuo Oilfield. After casing inspections, we came to know that faultage, voidage-injection imbalance and casing corrosion are the major causes of the casing damages there. Based on the above knowledge, corresponding measures such as casing patch, etc. are adopted in the monitored wells, which displays ideal results. A set of monitoring means of casing states in this kind of blocks has been worked out.
