The geothermal mining of HDR faces major challenges in the drilling and construction of wells, fracturing to create storage, and flowing to extract heat. Vibration impacts help improve the rock-breaking efficiency, where the axial\u2013torsional coupled vibration impact technology can increase the bit penetration depth and reduce the stick\u2013slip effect. To study the feasibility and efficiency of the axial\u2013torsional-coupled vibration impact-assisted Polycrystalline Diamond Compact (PDC) bit to break high-temperature and high-pressure rocks, a new experimental setup was designed. The system includes a drilling fluid circulation system, an axial\u2013torsional coupled impact drilling system, a formation simulation system, and a data acquisition and control system. This setup can produce a rock-breaking torque of 2000 N\u00b7m, a drilling speed of 200\u00a0rpm, a weight on bit of 100\u00a0kN, an axial vibration frequency of 100\u00a0Hz, and a torsional vibration frequency of 50\u00a0Hz. It can simulate the formation pressure of 70 MPa and the rock temperature of 400\u2009\u00b0C. A series of rock-breaking drilling experiments were successfully conducted using this setup. The results show that the axial\u2013torsional coupled vibration-impact assisted PDC bit has a good performance in breaking high-temperature and hard rocks, which can accelerate the application of this new technology in deep formation drilling.<\/jats:p>","DOI":"10.1063\/5.0174337","type":"journal-article","created":{"date-parts":[[2024,1,10]],"date-time":"2024-01-10T13:44:23Z","timestamp":1704894263000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["A novel experimental setup for axial\u2013torsional coupled vibration impact-assisted PDC drill bit drilling"],"prefix":"10.1063","volume":"95","author":[{"given":"Ran","family":"Ji","sequence":"first","affiliation":[{"name":"National Key Laboratory of Petroleum Resources and Engineering, China University of Petroleum (Beijing) 1 , Beijing 102249, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4662-7816","authenticated-orcid":false,"given":"Huaizhong","family":"Shi","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Petroleum Resources and Engineering, China University of Petroleum (Beijing) 1 , Beijing 102249, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8741-0832","authenticated-orcid":false,"given":"Zhongwei","family":"Huang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Petroleum Resources and Engineering, China University of Petroleum (Beijing) 1 , Beijing 102249, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3281-3295","authenticated-orcid":false,"given":"Wenhao","family":"He","sequence":"additional","affiliation":[{"name":"Beijing Key Laboratory of Optical Detection Technology for Oil and Gas, China University of Petroleum (Beijing) 2 , Beijing 102249, China"},{"name":"Basic Research Center for Energy Interdisciplinary, College of Science, China University of Petroleum (Beijing) 3 , Beijing 102249, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoguang","family":"Wu","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Petroleum Resources and Engineering, China University of Petroleum (Beijing) 1 , Beijing 102249, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinkang","family":"Fu","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Petroleum Resources and Engineering, China University of Petroleum (Beijing) 1 , Beijing 102249, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaowei","family":"Sun","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Petroleum Resources and Engineering, China University of Petroleum (Beijing) 1 , Beijing 102249, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Xiong","sequence":"additional","affiliation":[{"name":"College of Mechanical and Storage and Transportation Engineering, China University of Petroleum (Beijing) 4 , Beijing 102249, China"},{"name":"Center of Advanced Oil and Gas Equipment, China University of Petroleum (Beijing) 5 , Beijing 102249, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2024,1,10]]},"reference":[{"key":"2024011013440981500_c1","doi-asserted-by":"publisher","first-page":"134","DOI":"10.13745\/j.esf.2020.1.15","article-title":"Evaluation of geologic conditions for deep geothermal energy exploitation in China","volume":"27","author":"Pang","year":"2020","journal-title":"Earth Science Frontiers"},{"key":"2024011013440981500_c2","author":"National Energy Administration","year":"2018"},{"key":"2024011013440981500_c3","doi-asserted-by":"publisher","first-page":"111","DOI":"10.1016\/j.geothermics.2013.05.001","article-title":"Drilling into magma and the implications of the iceland deep drilling project (IDDP) for high-temperature geothermal systems worldwide","volume":"49","author":"Elders","year":"2014","journal-title":"Geothermics"},{"key":"2024011013440981500_c4","doi-asserted-by":"publisher","first-page":"11","DOI":"10.16082\/j.cnki.isn.1001-4578.2015.08.003","article-title":"Drilling difficulties and solutions for hot dry rock geothermal development","volume":"43","author":"Liu","year":"2015","journal-title":"China Petroleum Machinery"},{"key":"2024011013440981500_c5","doi-asserted-by":"publisher","first-page":"124505","DOI":"10.1063\/1.5125794","article-title":"Design of experimental setup for liquid nitrogen assisted polycrystalline diamond compact bit drilling","volume":"90","author":"Xiong","year":"2019","journal-title":"Rev.
