摘　　要：以视频图像作为可视化测井技术 ,通过对高温、高压、密封防护和视频信号无中继地远距离传输等技术难题的解决 ,成功开发了深井井底摄像测井系统 ,生动地显示了井底状况。详细分析了该系统实现的关键技术和解决方案。现场试验获得了井底状况 ,图像清晰。该系统性能稳定 ,在温度 110℃、2 5MPa压力下正常工作长达 5h ,总体性能指标达到了设计要求。By solving the key technical problems such as high-temperature resistance,high-pressure resistance,sealing,and long-distance video signal transmission, we have developed a down-hole optical imaging logging system that can display the situation of the down-hole clearly. The key techniques and solutions of the system are analyzed. The field log test indicates that the video pictures of the down-hole are visual. The system worked for 5 hours in the borehole with 110 ℃ and 25 MPa , showing its general performances meet the designed requirements.
