摘　　要：随着塔里木油田勘探开发的深入,老井数量逐年增多,其中,低效和无效的老井数量也在增加,因此,对老井的综合治理的需求日益迫切。在老井修井作业、开窗侧钻以及老井酸化压裂改造等综合治理作业前,获取准确的套管损伤信息尤为重要。多功能超声成像测井仪(MUIL)利用超声脉冲回波信号实现套损检测、固井质量及套外介质相态评价,提供套管变形、套管壁厚变化、套管穿孔、套管错位、套管回接等准确的套管信息。通过对比MUIL和60臂的多臂井径成像测井仪(MIT)在塔里木油田套管验漏以及开窗侧钻选层方面的测井应用结果,发现两者的套损检测结果基本一致,验证了MUIL具有较强的套损检测能力。此外,MUIL在塔里木油田储层改造选层和射孔层位验证方面的测井应用结果表明,MUIL能够为储层改造提供准确的套管信息以及验证射孔层位的有效性,为工程作业提供技术数据支持。根据MUIL在塔里木油田作业井的测井结果,建立了6类典型特征成像图版,可以快速识别套管损伤类型,为后续工程作业提供指导与帮助。With the deepening of the exploration and development of Tarim oilfield,the number of old wells has increased year by year,and the number of inefficient and ineffective old wells are increasing.Therefore,the comprehensive treatment needs of old wells has become urgent.It is particularly important to obtain accurate casing damage information before comprehensive treatment operations such as old well workover operations,window side drilling,and acid fracturing transformation of old wells.The multi-functiongal ultrasonic imaging logging tool(MUIL) uses ultrasonic pulse echo signal to realize casing loss detection,cementing quality and external medium phase evaluation,and provides accurate casing information such as casing deformation,change of casing wall thickness,casing perforation,casing misalignment,casing backconnection,etc.By comparing the logging application results of MUIL and 60-fingers multi-finger imaging tool(MIT) in casing leak detection and window side drilling and selection in Tarim oilfield,it is found that the casing loss detection results of the two are basically consistent,which verifies MUIL has a strong casing loss detection ability.In addition,the logging application results show that,MUIL in the selection of reservoir reconstruction and perforation level verification in Tarim oilfield can provide accurate casing information for reservoir transformation and verify the effectiveness of perforation position,and provide technical data support for engineering operations.Based on the MUIL logging results of workover wells in Tarim oilfield,6 types of typical imagine characteristics are established to quickly identify the type of casing damage and provide guidance and assistance for subsequent engineering operations.
