胡七南断块构造的确认及构造模型研究

Conformation and Its Structural Model of Southern Fault Block Hu7

为了真实地再现胡状集油田胡七南断块的地下地质模型,在三维地震资料分析构造特征的基础上,利用较密井网资料,绘制主要断层的断面等值线图,对主断层的断层面形态及局部构造高点进行构造的确认,使构造更加精确。在此基础上,利用合理的模拟方法建立断层三维模型,并以5m等高距编制构造等高线图。最后应用确定性建模方法,建立了胡七南断块的三维构造模型。可以看出,在构造重新研究的基础上,新发现了一些局部构造高点,所构建的断层模型和构造模型为下一步建立精确的地质模型奠定了坚实的基础。

To truly reproduce the underground geologic model of the southern Fault Block Hu7 in Huzhuangji Oilfield,on the basis of structural characteristic analysis with 3D seismic data,a fault section contour map of main faults was plotted by using more dense well pattern data,by which the fault sectional style and its structural high points of the main fault were proven for the purpose of making more precise structures.On the basis stated above,a 3D model was established with rational simulating methods,a contour map was drawn by 5m vertical interval.The determined modeling method is used to establish a 3D structural model of the southern Fault Block Hu7.it can be seen that on the basis of restudy of structures,local structural high points are newly found,the established fault model and structural model provide a solid basis for establishing a precise geologic model.
