ajst-5921	Li, Jian; Liu, Zhidi	Research on Improvement Measures of Cementing Acoustic Amplitude Logging	2023	6	.pdf	application/pdf	4920	184	43	The sonic method of cementing quality logging currently includes sound amplitude-variable density logging, sector cement cementing logging, etc. The main advantages of SBT logging over variable density logging are the division of the equipment into six zones around the well perimeter to measure cement cementing conditions, the lesser influence of the formation, the acoustic volume directional format that highlights the cement-formation interface effects and minimizes casing effects, the ability to accommodate in-well logging of different fluids, including: heavy and gas-bearing muds, the ability to measure in horizontal wells, and other advantageous features.	cache/ajst-5921.pdf	txt/ajst-5921.txt
