塔河油田复杂构造地质模型及模拟数据集

本数据集针对塔里木盆地塔河地区的主要构造类型设计理论速度模型，并通过声波方程有限差分法数值模拟获得理论模拟数据。该数据集包括四个理论模型及相应的模拟数据。1个三维复杂构造模型，包括陆相断陷盆地、叠置的曲流河道，高速的灰岩，海相的走滑断层及低速填充物（断溶体）等特征，由于三维模型较大，采用10m的网格进行建模，并抽取局部进行数值模拟获得了两条炮线的理论共炮集记录。3个二维复杂构造模型，采用小网格建模，其中双复杂构造模型包含了剧烈起伏的地表及地下复杂的断层模型，含高速火成岩的模型包含了复杂断陷盆地、陆相河道对应的小尺度低速体以及海相溶蚀孔洞等构造特征，深部陡倾构造模型包含了断陷盆地、高速灰岩、陆相小尺度低速体、陡倾断裂及低速填充物、双层溶蚀孔洞等构造；对二维模型采用高精度声波方程数值模拟，获得了3套理论模型数据。生成的理论模型数据在项目研究过程中，用于研究方法理论正确性及适用性的验证。

This dataset develops theoretical velocity models targeting the main tectonic types in the Tahe region of the Tarim Basin, and generates theoretical simulated data via numerical simulation using the acoustic equation finite difference method. The dataset includes four theoretical models and their corresponding simulated data. One 3D complex tectonic model is included, which features continental rift basins, superimposed meandering river systems, high-velocity limestone, marine strike-slip faults and low-velocity fillings (fault-karst bodies) and other geological characteristics. Given the large scale of this 3D model, a grid spacing of 10 m was adopted for modeling, and a local sub-region was extracted for numerical simulation to obtain theoretical common shot gather records from two shot lines. There are three 2D complex tectonic models, which were constructed with fine grids. The dual complex tectonic model includes sharply undulating surface topography and complex underground fault structures; the high-velocity igneous rock-bearing model contains structural features such as complex rift basins, small-scale low-velocity bodies corresponding to continental river channels, and marine dissolution pores; the deep steep-dip tectonic model includes rift basins, high-velocity limestone, small-scale continental low-velocity bodies, steep-dip faults and low-velocity fillings, as well as double-layer dissolution pores and other structures. High-precision numerical simulation based on the acoustic equation was conducted on these 2D models to obtain three sets of theoretical model data. The generated theoretical model data was used to verify the theoretical correctness and applicability of the research methods during the project research process.
