摘  要:在开发油气田进入生产末期时为了节约成本会将未被水泥固结的套管进行回收,为了确定回收套管的起始深度需要进行相应的测量得到套后水泥的分布情况。以往常常采用外方的测井仪器作业,导致费用高昂。中海油服在近年推出了具有完全自主知识产权的超声兰姆波成像测井仪(简称UCCS),首次在东海区域成功作业帮助油公司判断了套后水泥环分布状态,进一步指导了套管切割作业。When the oil and gas field is in the end of production,the casing that is not consolidated by cement will be recovered in order to save costs.In order to determine the initial depth of the recovered casing,it is necessary to measure the distribution of cement after the casing.In the past,foreign logging tools were often used for operations,which led to high costs.In recent years,COSL has launched an ultrasonic Lamb wave imaging logging tool(UCCS)with completely independent intellectual property rights.Its successful operation in the East China Sea region for thefirst time has helped oil companies judge the distribution of cement sheath behind the casing,further guiding casing cutting operations.
