Embodiment Construction
[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0015] The present invention refers to the attached figure 1 , 2 Be explained. Use the transmitting probe 1 (XMIT), the sector receiving probe 2 18 inches away from the transmitting probe, the SEC R (S1~SN), and 5 receiving probes R1~R5 equally spaced between 3 feet and 5 feet away from the transmitting probe. (3-foot receiving probe 3, 3.5-foot receiving probe 4, 4-foot receiving probe 5, 4.5-foot receiving probe 6, 5-foot receiving probe 7) and temperature probe 8 (TEMP) constitute the sound system. The special sound system composition of this design well solves various problems that may arise during the evaluation of cement bonding quality. At the same time, it can provide high-resolution acoustic signals with depth-shifting borehole compensation for exploration wells.
[0016] When this design is used for engineering logging, in addition to detecting ...
