压缩天然气地下储气井缺陷标定样管的研制

The Development of Defect Calibration Sample Tube on Compressed Natural Gas Underground Gas Storage Well

摘要: 通过分析CNG（压缩天然气）地下储气井常见缺陷，确定人工标定缺陷的形式、尺寸和分布，研制出一套CNG地下储气井缺陷标定样管，用于储气井的检测和相关研究，以解决储气井检测行业面临的缺少缺陷标定样管和参考标定信号的问题，为后期评价标准的制定奠定基础。

Abstract: This paper analyzes common defects of CNG underground gas storage well, determines manual calibration defect form, the size and distribution of the related defect in an attempt to develop a set of defect calibration sample tubes, which are to be used in gas storage well testing and research to solve the lack of defect calibration sample tubes, to provide reference calibration signal, and to lay the foundation for the establishment of the evaluation standard in the later stage.
