【摘要】 介绍了智能井的结构和优化控制方法,分类介绍了智能井井内监测技术和井外储层成像技术。在井内监测技术中,回顾了基于石英晶体谐振的永久井下测量仪以及基于拉曼背向散射和布拉格光栅技术的井下光纤传感器的工作原理、检测参数及油田应用;在井外成像技术中,详述了四维地震、连续电法测量、四维重力和井下雷达监测技术的原理、方法及研究进展。建议从技术层面和经济层面上综合考虑智能井传感器技术的发展。更多还原

【Abstract】 This paper introduces the structure and production control strategies of smart well technology,and reviews the in-well monitoring technology and reservoir imaging technology of smart well.In the in-well monitoring,we illustrate the operating principles,monitoring parameters,and field applications of Permanent Downhole Gauge based on resonant quartz crystals,and downhole permanent optic-fiber sensors based on backscattered Raman-band and Bragg-grating.In the reservoir imaging,we illustrate the operating principles,methods and research advances of 4D seismic,Dynamic Reservoir Drainage Imaging,4D gravity,and borehole radar.We suggest that both technological evolution and economic evaluation should be considered when developing smart well sensing technology.更多还原
