Nondestructive testing Underground metal component cement protective layer cemented sound wave Testing and evaluation of results

1 Scope

This standard specifies the sound wave detection method and results evaluation of the cement protective layer cementing of underground metal components. This standard applies to the cement quality of the external cement protective layer of the well tubular metal component vertically placed underground for storage of compressed gas. The sound wave detection method and the test result evaluation are applicable, and the applicable inner diameter of the member is 80 mm to 300 mm. Underground of other structures and specifications Metal components can also be referred to this standard.

Note. The transmitting sensor is used to continuously transmit acoustic signals, the short source receiving sensor is mainly used to receive well signals, and the long source receiving sensor is used to receive packets. Acoustic full wave trains including wellbore waves, formation waves and direct waves. ......
