摘　　要：多频声波测井技术可打破常规找漏找窜测井技术的局限性,探测深度较远且灵敏度高,对于多层管柱微小渗漏检测优势明显;与PLT技术组合测井可在常规分层合采井中获得套后各个射孔层精细产出贡献。该技术应用于海上油气田以来,在工程作业和生产井评价等方面取得了较好效果。解决了由管柱损伤漏失、完井工具失效和管外窜槽等造成井筒环空带压问题,可指导修井作业、提高作业时效、降低井控风险;弥补了单一产出剖面测试技术的不足,实现了分层合采井产液剖面的精细评价,可为生产井措施作业和区域油藏潜能分析提供有力依据。The multi-frequency acoustic logging technology breaks through the limitations of conventional leak and channeling logging technology,with a long detection depth and high sensitivity.It has obvious advantages in detecting small leaks in multi-layer pipe strings.With the combination of PLT technology,fine production contributions of each perforated layer after casing in conventional layered combined production wells can be obtained.Since its application in offshore oil and gas fields,good results have been achieved in engineering operations and production wells.The problems of wellbore annulus pressure caused by string damage and leakage,failure of completion tools and channeling outside the string are solved,which provides a guidance for well repair operations,improves operation efficiency,and reduces well control risks.Besides,it has made up for the shortage of single production profile testing technology and achieved fine evaluation of liquid production profiles in layered combined production wells,providing a good basis for production well measures and regional reservoir potential analysis.
