Abstract: Well log has two main technological responsibilities. One is to make rapid and accurate identification of the complicated rock characters at the oil and gas drilling site while the other is to make real-time and detailed appraisal of the oil, gas and water formations underground. This article briefs about the spectral log technology that is currently under research and application in the well log sector. It also overviews the advantages of spectral log technology, such as direct inspection of rock characters and oil bearing properties, quickness, precision and stability of inspection, and high digitalization. The article also focuses on some key technological points, such as spectrum information processing, geological calibration, spectrum analysis and spectrum geological appraisal, while analyzing the bottlenecks for on-the-field application of spectral log technology and the prospect for the future application and pointing out that this technology will become the main orientation for development of new well log technology in the future. This is of great importance to promote application of spectral log technology on the operational site.

Key words: well log technology, spectral log, research and application
