摘　　要：以评价渭河盆地氦等天然气远景为目的,2013年中国地质调查局启动了由西安地质调查中心实施的"渭河盆地氦气资源远景调查"计划项目,项目采取多单位联合攻关,多行业资料共享,物化探等多手段联合实施的工作方法,初步探索了氦气成藏模式和调查方法,总结了氦气富集成藏必须具备氦源岩、高效运移通道和载体气藏3大条件,得出渭河盆地具备良好的氦、甲烷等天然气成藏条件等成果,并提出渭河新生代盆地基底部分残存晚古生代煤系地层的新认识。The project of ＂helium gas resources survey in Weihe Basin＂ focusing on the prospect of helium gas resources in Weihe basin is a plan project approved by China Geological Survey in 2013, and organized by Xi＇an Center of Geological Survey. By multi units jointing, multi data sharing, and comprehensive geophysical and geochemical explorations, the helium gas accumulation models and survey methods have been preliminarily summarized. The resource rock, effective migration pathway, and reservoir of helium gas are the fundamental geological factors controlling helium gas accumulation, which have created the ideal conditions for helium and methane gas accumulation in Weihe basin. Furthermore, there are remnants of Upper Paleozoic coal measure strata at the basement of Cenozoic Weihe basin.
