Effective reservoirs in this region are relatively thin, and seismic responses between gas-bearing layers and dry layers differ only slightly. These geological complexities create substantial challenges for predicting tight sandstone reservoirs and gas-rich zones, which necessitate targeted and effective geological and geophysical prediction research. Therefore, taking the Second Member of the Qianfoya Formation (Qian-2 Member) as the research object, this study utilizes multiwell logging, mud logging, and 3D seismic data sets. We first analyze the geological characteristics of the target interval to clarify the primary controlling factors of tight sandstone gas reservoir enrichment. Based on these factors, we establish an effective geophysical prediction workflow tailored for gas-bearing tight sandstone reservoirs. This method is further applied to predict gas-rich zones within the Qian-2 Member. The study concludes that (1) the main controlling factors for tight gas reservoir enrichment in the Qian-2 Member are sedimentary facies distribution, reservoir-cap rock conditions, and fracture distribution. (2) Prestack simultaneous inversion integrated with rock physics analysis enables effective sand-body identification. Rock physics analysis identifies P-wave impedance (Zp) and S-wave impedance (Zs) as the sensitive parameter pair for sand bodies. A sand-body factor prediction model is then constructed via coordinate rotation. Sensitive parameters are derived from prestack simultaneous inversion, and the sand-body factor is calculated from the prediction model. High positive values of the sand-body factor are used to predict sand-body distribution. (3) Based on near- and far-offset seismic comparison, the dominant amplitude\u2013frequency method is used to extract the gas-bearing prediction attributes, whose positive anomalies effectively identify gas-bearing intervals. (4) A multifactor prediction framework combining sand bodies, gas-bearing properties, and fractures is adopted for gas-rich zones prediction. The results show that gas-rich zones in the Qian-2 Member are concentrated in the middle and upper submembers, and the predicted favorable zones are mainly distributed around faults. (5) This study establishes a workflow for predicting gas-rich zones of tight sandstone gas reservoirs via multifactor geological superposition analysis. Well-seismic calibration verifies its applicability, providing a methodological foundation and practical reference for the comprehensive prediction of favorable targets in similar tight sandstone gas reservoirs.<\/jats:p>","DOI":"10.1021\/acsomega.6c07726","type":"journal-article","created":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T12:01:48Z","timestamp":1790942508000},"page":"61823-61845","source":"Crossref","is-referenced-by-count":0,"title":["Analysis of Enrichment-Controlling\nFactors and Seismic\nPrediction of Gas-Rich Zones in Tight Sandstone Gas Reservoirs: A\nCase Study from the Second Member of the Qianfoya Formation in Bazhong\nArea, Sichuan Basin"],"prefix":"10.1021","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8713-0219","authenticated-orcid":true,"given":"Yuxuan","family":"Liao","sequence":"first","affiliation":[{"name":"Yangtze University , , ,","place":["Wuhan, China, 430100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jineng","family":"Jin","sequence":"additional","affiliation":[{"name":"Yangtze University , , ,","place":["Wuhan, China, 430100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1427-3096","authenticated-orcid":true,"given":"Jinxiong","family":"Shi","sequence":"additional","affiliation":[{"name":"Yangtze University , , ,","place":["Wuhan, China, 430100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ce","family":"Wang","sequence":"additional","affiliation":[{"name":"No.10 Oil Production Plant of Changqing Oilfield , ,","place":["Qingyang, China, 745100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6696-7068","authenticated-orcid":true,"given":"Shiqi","family":"Zhang","sequence":"additional","affiliation":[{"name":"China University of Petroleum (East China) , , ,","place":["Qingdao, China, 266580"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Yan","sequence":"additional","affiliation":[{"name":"Sinopec Exploration Company , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Wang","sequence":"additional","affiliation":[{"name":"Sinopec Exploration Company , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,2]]},"reference":[{"issue":"4","key":"2026101315072439300_cit1","doi-asserted-by":"publisher","first-page":"667","DOI":"10.1016\/S1876-3804(24)60505-7","article-title":"Distribution patterns of tight sandstone gas and shale\ngas","volume":"51","author":"Dai","year":"2024","journal-title":"Petroleum Exploration Development"},{"issue":"19","key":"2026101315072439300_cit2","doi-asserted-by":"publisher","first-page":"55034","DOI":"10.1007\/s11356-023-26279-9","article-title":"Effect\nof reservoir characteristics and chemicals on filtration property\nof water-based drilling fluid in unconventional reservoir and mechanism\ndisclosure","volume":"30","author":"Li","year":"2023","journal-title":"Environ.
