通过模拟井试验、水泥石强度与声波相对幅度关系试验、最佳测井时间选择试验及验窜等一系列试验。作者认为用声波幅度测井检查固井封固质量是可靠的,并提出用声波幅度检查固井封固质量的标准。但作者也认为,仅用这种方法是不全面的,应尽快采用声波幅度、声波变密度、井温和y-y测井四种方法来综合解释固井封固质量。
Through a series of experiments such as simulating well test, the relation between the strength of cement stone and the relative amplitude of acoustic wave, the selection of the best logging time and the test of channeling. The author thinks it is reliable to use acoustic amplitude logging to check the cementing quality of cementing, and put forward the standard of checking the cementing quality by acoustic amplitude. However, the author also believes that this method alone is not comprehensive. As soon as possible, four methods of acoustic amplitude, acoustic densification, well temperature and y-y logging should be used to comprehensively explain cementing quality.
