摘要
从俄罗斯引进的ECOS-31-7M过套管电阻率测井仪,由于没有伽马磁定位短节,给仪器组合测井校深作业带来诸多不便。文章针对这些问题,采用成熟的生产测井遥传技术,研制了配套的遥测伽马磁定位短节,同时下井及分别测量,较好地解决仪器校深问题,提高采集资料质量,缩短测井施工时间。
ECOS-31-7 M through casing resistivity logging tool,imported from Russia,has not GR/CCL sub,which brings much inconvenience to depth correction and well logging operation.The paper introduces a telemetry GR/CCL sub which is developed to go with the logging tool.The two tools can be run simultaneously and controlled by voltages to make required downhole measurement.The problem of depth correction with ECOS-31-7 is well solved,and logging data quality and well logging efficiency are improved.
