| 摘 要： | 经过大量学者多年的研究总结，川西坳陷中段新场地区具备良好的生、储、盖等成藏组合。结合地质背景及碳同位素、轻烃的研究，认为新场地区天然气主要是Ⅲ型干酪根的煤型气，气藏主要分布在上三叠系的须二段和须四段，以及中侏罗系、上侏罗系地层中。

| Abstract: | Previous study indicates that there is good source-reservoir-caprock association in the Xinchang area, middle section of west Sichuan depression. Study of geological setting, carbon isotope composition and light hydrocarbon shows that natural gas in the Xinchang area consists mainly of coal-type gas of Ⅲ-type kerogen. The most of gas reservoirs occur in the second and forth Members of the Upper Triassic Xujiahe Formation and the Middle and Upper Jurassic. |
