摘　　要：针对油田日益严重的套损问题,准确了解井下套损情况,制定有针对性的治理方案迫在眉睫。应用超声成像技术的小直径井壁超声成像测井仪,在套损检测中,能准确判断套管腐蚀、穿孔、破裂、错断、变形、丝扣脱落等情况,所反映的套损类型及程度清晰、明显、直观,在特殊井取证和报废井的决策中起到了一定作用。Facing the increasingly serious casing damage problem,it is important to formulate targeted governance scheme based on understanding the situation of the underground casing damage. In the casing damage detection,the minor diameter shaft wall ultrasonic imaging logging instrument is used which adopts the ultrasonic imaging technique. It can judge the situation about casing damage such as corrosion,perforation,damage,offset,distortion,screw off and so on exactly. And it also can play an important role to obtain information in special well and make the decision to the abandon well.
