| 摘 要： | 经测试,南盘江盆地秧1井天然气可分为2类:一类为高含N2天然气,N2含量为54.92%~73.89%;另一类为高含CO2天然气,CO2含量大于96%。认为高N2天然气是秧1井乃至南盘江地区具有地质意义的天然气。指出该类天然气甲烷含量一般小于2.5%,几乎不含大于乙烷的烃类组分,CO2含量2.2 7%~9.5 4%;1δ3C1值为-3 3.1 9‰~-3 3.9‰,CO2的1δ3C值为-2 9.3‰~-30.93‰。认为该类天然气不是原油裂解气,也不是源自上二叠统龙潭组的煤成气,而主要是源自中泥盆统泥质烃源岩的干酪根裂解气;中泥盆统泥质烃源岩的“晚期阶段聚气”是造成该地区天然气高含N2、烃类组分碳同位素偏重的主要原因。 |

| Abstract: | The gases can mainly be divided into two groups being with high N_2 and high CO_2 in the gas shows of Well Yang1.But,according to the gas analysis and the fact that all gases shows in Nanpangjiang area are with high N_2,the high N_2 gas in Well Yang1 is actual geological significant.The kind of the gas is featured with high N_2 content and heavier isotopic values,the N_2 content is from 54.92% to 73.89%,the δ~(13)C_1 values are from-33.19‰ to-33.9‰.The gas in Well Yang1,not being the cracked gas from crude ... |
