摘要
在综合考虑模拟区几何模型的形状及大小、区域构造格架、边界条件的情况下,选择与地质构造相适应的力学模型,并以实测地应力(压裂法、声发射法)为约束条件,利用有限元现今地应力场模拟方法计算了模拟区地应力场的平面和剖面展布及其特征,模拟结果可为生产单位科学开发管理油气藏提供参考。
Considering the shape and size of simulation geometric model, regional tectonic framework and boundary conditions, the dynamic model which is fit to the geological structure were selected. Using the measured stress data (fracturing method, AE method) as constrained conditions, the plane and profiles of stress distribution and characteristics of the simulated area was calculated using finite element in-situ stress field simulation. The results provide scientific reference to reservoir development and management.
