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。新851井、新2井等气井的发现,更加坚定了大家对新场地区天然气资源的信心。结合地质背景以及碳同位素和轻烃的研究发现,新场地区天然气主要是Ⅲ型干酪根的煤型气,天然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(J2q、J2s+x)、上侏罗系(J3p)地层中。因此,此次研究的重点落实在以上层位气藏的天然气研究上。
With the many-years' research by lots of scholars,it is concluded that XiChang of the middle member of western Sichuan Depression area possesses unique play of source,storage and cover.The discovery of Well X851#,X2# and other wells gives us firm belief about the resource of Xichang.Based ong the geology background and the research about carbon isotope and light hydrocarbon,we find that the natural gas in Xinchang is mainly coal related gas from type-Ⅲ kerogen.The gas pools mainly are in Xu-2 and Xu-4 of the upper Triassic,the middle Jurassic(J2q,J2s+x)and the upper Jurassic(J3p).Therefore,the our research concentrate on the gas pools in the above mentioned formations.
