摘　　要：MSC MARC的高度非线性有限元分析能力与强大的二次开发接口为复杂三维地质数值模型的建立与三维构造应力模拟与非线性分析提供了有力工具;并可以通过二次开放子程序建立复杂的岩石本构与破裂准则。本文基于MSC MARC建立了新疆焉耆盆地宝浪油田宝北区块背斜构造三维有限元模型并进行了构造应力模拟分析和裂缝预测。裂缝预测结果与实际动态资料十分吻合。MSC MARC is a nonlinear FEA program. Its ability of highly nonlinear finite element analysis and good secondary development interface enable us to construct a complicated 3D geological numerical model and perform 3D tectonic stress modeling and nonlinear analysis, and complex constitutive equations and fracture critera of rocks can be established by secondary open subroutines. Based on the finite element analysis software MSC MARC. a 3D finite elemant model of the Baobei anticline the Yanqi basin, Xinjiang, is established, and the simulation analysis of the tectonic stress field and fracture forecasting are performed. The predicted regions with high-density fractures are in agreement to the real case.
