天然气中~4He丰度分析及应用
ANALYSIS AND APPLICATION OF ~4He ABUNDANCE IN NATURAL GAS
摘要
Abstract
A rare gas purification and accumulation system is designed and used in analysis of ~4He abundance in natural gas together with mass spectrograph. Sensitivity of ~4He is calculated. The system is proved reproductive. Data from natural gas analysis are compared with those from Mat271 mass spectrograph, and deviation is less than 10%. Natural gas from the Puguang and Jiannan gas fields in the Sichuan Basin is analyzed, indicating that, studies of ~4He abundance in natural gas is significant for age research of natural gas source rocks and accumulation formation.关键词
