The acoustic anisotropy measurement of cores in these reservoirs can guide drilling, well logging, and exploitation. However, almost all core holders are designed for cylinder cores, which are not suitable for all-directional measurements. A three-dimensional measurement device was designed on the basis of the cross-hole sonic logging method. This device mainly consisted of two pairs of transducers, a signal generator, an oscillograph, an omnidirectional positioning system, and a computer control system. By adjusting the measurement latitude and longitude circle automatically, this device scanned spherical sample rocks and obtained full-wave waveforms in all directions. Experiments were performed taking granite from the Jiaodong Peninsula, China, as an example, and the arrival times and velocities of the longitudinal and shear waves were calculated based on the full-wave waveforms. Thereafter, anisotropic physical characterizations were carried out on the basis of these velocities. These data play an important role in guiding formation fracturing and analyzing the stability of borehole walls.<\/jats:p>","DOI":"10.3390\/s22239473","type":"journal-article","created":{"date-parts":[[2022,12,5]],"date-time":"2022-12-05T08:10:57Z","timestamp":1670227857000},"page":"9473","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Three-Dimensional Acoustic Device for Testing the All-Directional Anisotropic Characteristics of Rock Samples"],"prefix":"10.3390","volume":"22","author":[{"given":"Kai","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Geosciences and Technology, China University of Petroleum, Qingdao 266555, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6720-4978","authenticated-orcid":false,"given":"Shengqing","family":"Li","sequence":"additional","affiliation":[{"name":"School of Geosciences and Technology, China University of Petroleum, Qingdao 266555, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuanda","family":"Su","sequence":"additional","affiliation":[{"name":"School of Geosciences and Technology, China University of Petroleum, Qingdao 266555, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9744-4817","authenticated-orcid":false,"given":"Baohai","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Geosciences and Technology, China University of Petroleum, Qingdao 266555, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjie","family":"Wu","sequence":"additional","affiliation":[{"name":"Yichang Chengfa Gezhouba Gas Development Corporation, Yichang 443000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shoutao","family":"Xin","sequence":"additional","affiliation":[{"name":"ChangQing Branch of CNPC Logging, Xi\u2019an 710200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,4]]},"reference":[{"key":"ref_1","first-page":"156","article-title":"Dissociation behavior of hydrate core sample using thermodynamic inhibitor\u2013Part 2: Experimental investigation using long core samples","volume":"18","author":"Kawamura","year":"2008","journal-title":"Int.
