构造建模是储层建模的基础，对于构造面貌极其复杂的断块群油气藏，它所建立的构造模型不仅提高了对断块群构造展布特征描述的精度，同时也为储层的相建模和储层参数建模提供了良好的地层格架模型，从而有利于研究断块群油藏的分布特征及断层对其的影响作用。应用构造建模的基本原理和步骤，获得了江家店油田夏502断块沙三下和夏509断块沙四段砂层组的构造模型，为后续油藏特征的研究提供了良好的模型基础。

Structure modeling is the basis of reservoir modeling. For the fault-block group whose structural features are extremely
complex袁the established structural models not only improve the descriptive accuracy of the structural characteristics of fault-block袁
but also provide the formation framework model for facies modeling and reservoir parameters modeling袁which is helpful to study the
distribution of fault-block group and the influence of faults on it. The sands structure models of the lower Es3 member of Block Xia
502 and the Es4 member of Block Xia 509 have been obtained through the basic structural modeling principles and steps袁which
provides a good modeling basis for the following research of reservoir characteristics.
