济阳拗陷孔店组烃源岩的地震预测方法
|
摘要
烃源岩的分布研究与生烃量的计算是含油气盆地勘探的重要内容。在没有钻井直接钻遇烃源岩的情况下,如何研究其分布甚至计算生烃量非常困难。本文利用地震资料,通过地震相和地震速度特征的分析,较准确地预测了东营凹陷孔店组二段潜在的烃源岩,并提出了资源系数的概念,计算了该套烃源岩的生烃量。预测结果经随后的钻井证实,说明利用地震资料预测烃源岩的方法是可行的、有效的,从而使得困扰济阳拗陷深层勘探几十年的油源问题得以初步解决,证实济阳拗陷深层同样具有较大的勘探潜力。此法可用于无探井区和低勘探程度区,具有较高的推广应用价值。
The study of distribution of source rock and computation of hydrocarbon-produced capacity are the important contents of exploration of hydrocarbon-bearing basins, It is very difficult to study its distribution and even to compute the hydrocarbon-produced capacity in a situation of without directly drilling into source rock. Using seismic data and through analysis of feature of seismic facies and seismic velocity, the paper correctly predicted the potential source rock in Kongdian Group second Segment of Dongying sag, presented a conception of resource factor and computed the hydrocarbon-produced capacity of the set of source rock. The predicted results have been proved by following drilling results,which illustrated that using seismic data to predict source rock is feasibility and effectiveness , thus the source issue that had troubled the deep exploration of Jiyang depression for some dozens of years has been preliminary solved,which proved that the deep of Jiyang depression has also the large potential of exploration. The method can be used in the areas without drilling and lower exploration degree,having higher popularized value.
