摘要
为了实现嵌入式离散裂缝模型(EDFM)的维度升级,使EDFM能够有效处理任意形状的倾斜裂缝面,提出一个适用于任意形状裂缝面的三维EDFM前处理算法,提供了解决EDFM维度升级关键困难的一种具体思路,继而依据该前处理算法实现了能够适用于任意形状倾斜裂缝面的三维EDFM,并在本文中给出了具体的数值案例,说明了所提前处理算法的有效性。
In order to realize the dimension upgrade of embedded discrete fracture model(EDFM),and make EDFM effective for arbitrary-shape inclined fractures,a 3D EDFM pre-processing algorithm for arbitrary-shape fractures was presented,a specific idea to solve the key difficulty of dimension upgrade of EDFM was provided.Subsequently,according to the pre-processing algorithm,a 3D EDFM adaptive to arbitrary-shape inclined fractures was realized,and a corresponding numerical example was implemented to illustrate the validness of proposed algorithm.
