摘要
本文运用地层压实校正法恢复金湖凹陷不同区块的地层埋藏史、生油岩埋藏史。根据镜质体反射率与古地温的关系,恢复了凹陷的古地温和古地温梯度,计算出生油岩在各地史时期的TTI值。在上述方法研究的基础上,建立了生油岩热演化的地温地质模型,划分出金湖凹陷阜二、阜四段两套生油岩在地史时期的演化。
The Stratigraphic Compaction Correlation Method is used in this paper to restore the burial history of strata and oil source rocks for different blocks of the Jinhu Depression. According to the relationship of vitrinite reflectance to paleo geotemperature, the paleo geotemperature and paleo geothermal gradient of the Depression are restored, and the TTI value of oil source rocks during each period of geohistory is calculated. On the basis of above method research, the geotemperature geological model for the thermal evolution of oil source rocks is established, and the evolutionary and hydrocarbon generating stages and oil generating thresholds for Fu 2 and Fu 4 two sets of oil source rocks in the Jinhu Depression during the period of geohistory is classified.
