摘　　要：传统生产测井工艺的井下测试仪器易被塔里木东河油田注气受效井井筒内沥青质糊死,不能完成涡轮流量曲线测量,流体密度测量也受到较大影响。引进的连续油管光纤测井技术将光纤穿入连续油管内,随着连续油管下入井中,实现全井段的温度和声波等参数实时测量。测井过程中不需要来回移动光缆,消除了传统测试工具必须在井中来回移动测量扰动井内环境平衡造成的数据偏差,使测井结果更高效、更准确。结合油藏、地质工程数据,对解释成果进行分析,结果与实际生产情况相符,验证了连续油管分布式光纤测井的适用性和技术优势。该技术在××1-10H井成功应用,为油田油气井动态监测提供了新的技术手段。In the Donghe oilfield,the Tarim Basin,the downhole testing instrument used in traditional production logging process is easily smeared by asphaltene in wellbores affected by gas injection,which disables the measurement of turbine flow curve and also impedes the measurement of fluid density.The imported coiled tubing optical fiber logging technology can realize the real-time measurement of parameters such as temperature and sound waves in the entire wellbore,by penetrating the optical fiber into the coiled tubing to allow it run together with the coiled tubing into the wellbore.The logging results are more efficient and accurate,since this technology does not need to move the optical cable back and forth,as do as traditional testing tools which must be moved to realize measurement,which disturbs the environmental balance in the wellbore and thus leads to data deviation.Combined with reservoir and geological engineering data,the interpretation results were analyzed.The analysis results are consistent with the actual production situation,which verifies the applicability and advantages of the coiled tubing distributed optical fiber logging technology.This technology was successfully applied in Well××1-10H.It provides a new option for dynamic monitoring of wells.
