Abstract—Using actual examples, we have studied the abilities of seismic-gravity modeling for territories that differ in the features of their physical and geological structure, scope of study, and level of data. It is shown that it is impossible to formalize a unified approach to developing a seismic-density model since the modeling technique is inevitably changed according to the physical and geological situation, as well as the completeness and the quality of a priori data. The degree of effectiveness of seismic-gravity modeling depends on the geological features of the cross-section, that is, the extent of compartmentalization of the geometry of the reflector horizons, the contrast and depth of the density boundaries, the complexity of the geological development of the region, and the acquisition parameters for the modeling.

摘要——通过实例，我们研究了物理地质结构特征、研究范围和数据水平不同的地区的地震-重力模拟能力。结果表明，建立地震密度模型的统一方法是不可能的，因为建模技术不可避免地会根据物理和地质情况以及先验数据的完整性和质量而改变。地震-重力模拟的有效性程度取决于横截面的地质特征，即反射层几何的划分程度、密度边界的对比度和深度、地质发育的复杂性区域，以及建模的采集参数。
