As a strategic and scarce resource, the assessment of helium accumulation potential holds significant importance for unconventional petroleum exploration. This study systematically evaluates helium resources in Ordovician formations of the Gucheng area, Tarim Basin, by integrating uranium (U) and thorium (Th) concentration analysis with natural gamma-ray spectrometry (NGS) logging, based on radioactive element decay theory. Key findings include: (1) Trace element analysis of 49 rock samples reveals notable differences in U and Th enrichment among various lithologies, with U content decreasing from shale (12.8±3.2 ppm) > high-U dolomite (8.5±1.6 ppm) > argillaceous limestone (5.2±0.9 ppm) > dolomite (3.1±0.7 ppm) > limestone (2.3±0.5 ppm), and Th content from shale (24.6±5.4 ppm) > argillaceous limestone (16.3±3.1 ppm) > dolomite (9.8±2.3 ppm) ≈ high-U dolomite (9.5±2.1 ppm) > limestone (7.2±1.8 ppm). (2) NGS data from 15 wells indicate a total helium generation of 13.91 km³ (standard conditions), with the Qierqieke Formation contributing 83.5% (11.62 km³) as the primary helium source rock. Secondary contributors include the Lower Yingshan (1.29 km³, 9.3%), Upper Yingshan (0.41 km³, 2.9%), and Penglaiba (0.35 km³, 2.5%) formations, while the Yijianfang and Tumuxiuke formations show minimal contributions (
