摘要
沧东凹陷作为黄骅坳陷的主要富油气凹陷之一,如何正确认识其孔二段烃源岩的分布,研究生烃特征是勘探部署和潜力评价的重要基础。通过对沧东凹陷孔二段的烃源岩分布特征、有机质丰度特征、有机质类型、有机质演化等进行系统的细化研究,研究表明孔二段是沧东凹陷的一套主力优质烃源岩,主要分布大段的油页岩和高丰度的泥岩,具有有机质丰度高,类型好,成熟度适中,并富含易于早期生烃的丛粒藻,生烃潜力巨大。
Cangdong sag is a major sag rich of petroleum in Huanghua depression,how to correctly understand the distribution of its Ek2 source rock characteristics is an important foundation graduate hydrocarbon exploration potential deployment and evaluation.As a systematic study of the distribution of the Ek2 source rocks in Cangdong Sag,characterized by the abundance of organic matter,organic matter type,organic evolution and other studies have shown that is the main quality of a hydrocarbon source rock,it mainly has oil shale and high abundance of large segments mudstone with high organic matter abundance,good organic type,moderate maturity and plenty of the earlier hydrocarbon generations of botryococcus braunii,huge hydrocarbon generating potential.
