【摘要】：伊通盆地位于郯廬斷裂帶北段西半支的佳伊斷裂帶內(nèi),斷陷面積3500km2。幾輪油氣地質(zhì)綜合研究揭示了岔路河斷陷暗泥厚度最大,但探明儲量卻不高,鹿鄉(xiāng)斷陷五星構(gòu)造帶原油來源不明,這影響了該區(qū)的深入勘探開發(fā)。伊通盆地在縱向上發(fā)育始新統(tǒng)雙陽組、奢嶺組和永吉組三大烴源巖系,本文通過對不同層位烴源巖的平面發(fā)育情況、有機(jī)質(zhì)豐度、有機(jī)質(zhì)類型、有機(jī)質(zhì)成熟度研究表明,它們有很大差別,反映烴源巖對油氣的生成貢獻(xiàn)不同。從縱向上看,研究區(qū)內(nèi)烴源巖顯示出隨著層位由老到新其生烴能力由好到差的規(guī)律,其中雙陽組有機(jī)質(zhì)發(fā)育程度高,有機(jī)質(zhì)豐度高,成熟度適中,是伊通盆地的主要烴源層。在橫向?qū)Ρ戎胁砺泛訑嘞轃N源巖有效生烴能力強(qiáng)的層位最多,鹿鄉(xiāng)斷陷次之,莫里青斷陷相對最少。伊通盆地原油地球化學(xué)特征相似,從油源對比上來看不同源,但可以說明伊通盆地原油母質(zhì)類型相似,在物性上岔路河斷陷與鹿鄉(xiāng)斷陷和莫里青斷陷有所差異,可能是由于岔路河斷陷埋深大,成熟度高造成的。
[Abstract]:The Yitong basin is located in the west half branch of the Tan-Lu fault zone with an area of 3500km2. Several comprehensive studies of oil and gas geology reveal that the thickness of dark mud in Chailuhe fault depression is the largest, but the proven reserves are not high, and the source of crude oil in Wuxing structural belt of Luxiang fault depression is unknown, which affects the further exploration and development in this area. The Eocene Shuangyang formation, Ailing formation and Yongji formation are developed longitudinally in the Yitong Basin. The study on the plane development of the source rocks, the abundance of organic matter, the types of organic matter, and the maturity of organic matter in different layers of Yitong Basin show that: They differ greatly, reflecting the different contribution of source rocks to oil and gas generation. From the longitudinal point of view, the hydrocarbon source rocks in the study area show the regularity of hydrocarbon generation ability from old to new with the horizon from good to bad. The Shuangyang formation has a high degree of organic matter development, high organic matter abundance and moderate maturity, and is the main hydrocarbon source bed in Yitong Basin. In the horizontal correlation, the strata with strong effective hydrocarbon generation ability of source rocks in Chailuhe fault depression are the most, Luxiang fault depression is the second, and Morri Qinqing fault depression is relatively least. The geochemical characteristics of crude oil in Yitong basin are similar, which are different from oil source correlation, but it can be concluded that the oil source material types in Yitong basin are similar, and the physical properties of Chailuhe fault depression are different from those of Luxiang fault depression and Morri Qing fault depression. This may be due to the deep burial and high maturity of the Chalu River fault depression.
