陕西渭河盆地氦气资源赋存状态及其意义

氦气资源是一种稀有紧缺性战略资源。渭河盆地具有良好的氦气资源显示，前人认为区内氦气及伴生气资源为水溶气。通过已有石油井、地热井录井、样品测试、动态监测等资料分析，认为渭河盆地不仅存在水溶气资源，也存在游离态氦及伴生气资源，即具有富氦天然气层（藏），这一认识对进一步的氦气资源评价与开发利用具有重要意义。

Mode of occurrence of helium in Weihe Basin, Shaanxi Province and its significance

Helium (He), a kind of rare and strategic resource, occurs well in Weihe Basin. According to previous views, the resource of He and its associated gas may belong to water soluble gas, and the further evaluation and development are restricted by its hard development and low interest. Therefore, it is significant to identify the mode of occurrence of He resource. Based on the data analysis of dynamic monitoring, logging and samples from petroleum wells and geothermal wells, it can be inferred that not only water soluble gas resource but also resource of free state He and its associated gas are developed in Weihe Basin. In other words, abundant He reservoirs may exist in Weihe Basin. This new opinion is important for further evaluation and development of the resource.
