| 摘 要： | 阿克1井是在塔里木盆地喀什凹陷获得工业气流的第一口探井,与该盆地其他地区相比,其天然气地球化学特征有着独特性:干燥系数大,非烃气体含量较高,甲烷碳同位素异常重(居塔里木盆地已发现的天然气之首),稀有气体3He/4He、40Ar/36Ar比值较大。根据区域烃源岩发育特征、源岩地球化学特征和热演化史,初步确定阿克1井的气源岩以石炭系为主。

| Abstract: | Well Ake 1 is the first exploratory well where commercial gas stream was found in Kashi sag in the west of Tarim basin.Geochemical features of its natural gas have idiographic properties with the contrast of ones of the others in Tarim basin:high desiccation coefficient, high content of CO2 and N2;heavy carbon isotope of CH4, which is the heaviest in Tarim basin;high value of rare gas 3 He/4 He and 40Ar/36 Ar.We elementarily ascertain the prime source rock of gas of well Ake 1 is Carboniferous by growing feature of regional source rock ,combining geochemicalfeatures of source rock and history of heat evolving. |
