三维构造模拟方法──体平衡技术研究

THREE DIMENSIONAL STRUCTURAL MODELING: VOLUME-BALANCE TECHNIQUE

为了实现三维构造史模拟，在二维平衡剖面技术的基础上，提出了适用于三维构造模拟的方法──体平衡技术，其核心是通过分析断层演化及地层变形在三维空间中的特殊性，建立三维复杂构造的数学模型和三维物质平衡方法，它简化了平衡时三维的体积计算和对不平衡体积构造体的适应性，从而减小了三维构造模拟的实现难度。

This paper presents, on the basis of the 2-D profile technique, the volume-balance technique that is appropriate for the 3-D structural medeling in order to actualize the simulation of the 3-D structural history. The core of this technique is to establish the mathematical medel of the 3-D complex structure and the method for the 3-D material balance, using the specificity of the fault evolution and the strata deformation in 3-D space instead of in 2-D space. This technique simplifies the calculation process of the 3-D volume in balance and increases its adaptability to the non-balance volume structural body, thus reducing the difficulty in the actualization of the simulation of the 3-D structure medeling.
