This standard specifies the calibration methods, requirements and cementing quality evaluation methods for cement bonded logging tools (CBL/VDL) (abbreviated as instruments) in calibrated wells. This standard is applicable to cement bonding logging tools (CBL/VDK,) and similar instruments for the evaluation of gradation and cementing quality in calibrated wells. Other related instruments such as SBT, UCT (CBET) and CET (or PET) and other logging instruments The calibration methods and requirements should be formulated with reference to this standard.
