摘　　要：数值模拟技术是对储层构造裂缝进行定量预测及确定构造缝缝空间分布的一种有效方法。该项技术是根据构造变形反演研究区域的边界条件及根据地质模型用有限元方法进行正演计算，确定出研究区的应力场，再结合岩石破裂准则确定裂缝的空间分布。储层构造裂缝数值模拟技术中有若干项关键技术，包括模型的建立、断层的处理、反演标准的确定和裂缝密度的计算等。文中针对不同油田的实际情况，对各个技术关键制订出了合理的解决方案。该项技术通过在若干油田的应用研究，形成了一整套定量预测储层构造裂缝的技术方法。经实践证明，该项技术对裂缝性油气藏的勘探、开发是一种可行而实用的方法。Numerical simulation technique is a valid way to quantitatively predict parameters of structural fractures in a reservoir.This technique first inverts boudary conditions of a study area based on structural deformation characters,then completes forward modelling for a geological model using the Finite Element Method to determine the stress field of the area,which are combined with rupture criterion of rocks to determine parameters of structural fractures. Numerical simulation technique for structural fractures in a reservoir includes some key methods,such as establishment of a model,treatment of faults in the model,determination of inversion criterion and calculation of fracture density.In accordance with the situation of different oilfields,this paper provides suitable schemes for implementation of these methods. The technique is tested by application in several oilfields,and formed as a complete series of methods to predict parameters of structural fractures in a reservoir.The result proves that it is a practicle technique for exploration and development for fracture type hydrocarbon reservoirs.
