SJC-2B小井眼变密度测井仪及其应用

SJC-2B Slim-hole Variable Density Logging Tool and Its Application

介绍了SJC-2B小井眼(43mm)变密度测井仪的结构、原理、技术指标及信号流程。对仪器信号的影响因素及其测井应用进行了分析。总结了仪器的适用条件和在小井眼、生产井及水平井固井质量评价中的作用。但该仪器在大井眼、煤层等慢速地层、低密度固井井段,声幅及变密度曲线有失真现象。

Introduces the configuration, principle and specification of SJC2B slim-hole variable density logging tool; Describes its log application and affected factors on its signals; Summarizes its adaptive conditions and role in cementing quality of slim-holes, production wells and horizontal wells. But, SJC2B tool′s acoustic amplitude and variable density signals become distortional in large boreholes, slow formation such as coal beds, and so on.
