Progress and Achievements of Helium Gas Resources Survey in Weihe Basin

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.
