黄骅坳陷孔南地区是我国较早发现未熟-低熟油地区之一,为了进一步研究其烃源岩生、排烃特征,为未熟-低熟油的研究和资源评价提供支持,对该区主要生油层孔二段泥岩和次要生油层沙一下段页岩进行了热压模拟试验,并在此基础上编制了二类烃源岩生、排烃模式。模拟研究表明:这二类烃源岩都有明显的早期生、排烃的特征,且生排、烃潜力大,说明该区烃源岩具备形成未熟-低熟油的能力,具有良好地勘探前景。
The Kongnan area in Huanghua Depression is one of the earliest immature-low mature oil areas discovered in China. In order to further study its characteristics of source rock exudation and hydrocarbon expulsion and provide support for the research and resource evaluation of immature-low mature oil, In the second member of the second member of the second member of Shahejie Formation, the second member of Shahekou Formation, the second member of Konggoushan Formation and the second member of Shahejie Formation, the second member of Shahejie Formation is formed. The simulation results show that these two types of source rocks have obvious characteristics of early generation and hydrocarbon expulsion, and the potential of raw hydrocarbon generation and hydrocarbon generation is large, indicating that the source rocks in this area have the ability to form immature-low mature oil and have good prospecting prospect.
