| 摘 要： | 揭示伊通盆地岔路河断陷复杂的油气成藏历史,对指导伊通盆地油气勘探具有十分重要的意义.一维数值模拟结果显示:岔路河断陷主要烃源岩在始新世中、晚期进入生烃门限;渐新世早、中期达到生烃高峰.通过对岔路河断陷双阳组-永吉组砂岩储层流体包裹体样品中有机包裹体的荧光特征、均一温度以及共生盐水包裹体均一温度等分析,结果表明,岔路河断陷至少经历过3期油气充注;结合埋藏史热史分析,确定出油气充注分别发生在距今38.1～27 Ma、19.5～10 Ma和1～0 Ma,与生排烃史模拟结果有很好的一致性.结合盆地构造演化认为古近纪末期和新近纪晚期两期构造抬升两度中止了油气充注过程,最终形成了该断陷始新世晚期-渐新世中期、中新世早-中期和第四纪3个重要的油气成藏时期.

| Abstract: | It is very significant to probe the complex charging history in Chaluhe depression of Yitong basin.1D numeric modelling of hydrocarbon generation and expulsion history of source rocks in 4 wells confirms that the major source rocks had entered their threshold of maturity at the Middle-Late Eocene and reached the peak generation stage at the Early-Middle Oligocene.For this study,145 fluid inclusion samples from 19 wells have been employed to systematically obtain information on fluorescent colors of hydrocar... |
