二叠纪特拉华盆地是一个复杂的系统,其中有机质的成熟受到二叠纪后可用数据中不明显的事件的影响。在这项研究中,作者旨在通过恢复区域横截面并进行有机质成熟度模拟来确定特拉华盆地各种地质控制对碳氢化合物成熟度的影响。将这些数据与盆地中地层层段的地震解释相结合,用于完善所得到的二维热模型的结构恢复和校准。

方法

作为对后二叠纪地层进行初步评估的直接信息来源,我们对地表地质图、残余厚度图和从文献中收集的结构信息进行了检查。接下来,为此目标选择了四个区域横截面并进行了重新研究。

2D Restorations and Basin Modeling Provide Insight Into Formation Maturation

The authors of this paper aim to identify the effect of various geologic controls on hydrocarbon maturation in the Delaware Basin by restoring regional cross sections and performing simulations of organic-matter maturity.

The Permian Delaware Basin is a complex system in which the maturation of organic matter is affected by events not evident in the post-Permian available data. In this study, the authors aim to identify the effect of various geologic controls on hydrocarbon maturation in the Delaware Basin by restoring regional cross sections and performing simulations of organic-matter maturity. Integration of these data with seismic interpretation of the stratigraphic intervals present in the basin is used to refine the structural restorations and calibration of resulting 2D thermal models.

Methods

As a direct source of information for the initial evaluation of the post-Permian layers, surface geological maps, residual thickness maps, and structural information collected from the literature were examined. Next, four regional cross sections were selected and restudied with this objective.
