摘    要:根据控制裂缝发育的内外因素,提出了定量预测低渗透油气储集层裂缝空间分布的三维有限元数值模拟方法。从岩石的脆性破裂理论出发,在建立合理的地质模型、力学模型和数学模型的基础上,通过构造应力场的数值模拟计算,并结合实际的岩石破裂准则,可定量地预测裂缝的空间分布规律。经过多个油田应用和实践证明,该方法具有较高的符合率,对指导隐蔽性油田的勘探具有重要的意义。

关 键 词:低渗透储集层  裂缝  定量  预测  数值模拟  空间分布

Abstract:Based on internal and external factors controlling the fracture development in low-permeability reservoir, a 3D-infinite mathematical modeling technique which can quantitatively predict the spatial distribution of fractures is proposed. Starting from the rock brittle fracturing theory, the space distribution regularity of fractures can be quantitatively predicted through numerical simulation of tectonic stress field combining with the actual rock cracking criterion, based on establishment of proper geological model, mechanical model and numerical model. A series of application to many fields-shows that this method has a high coincidence rate, and is of great importance to guide the exploration of subtle oil-gas reservoir.
Keywords:Low-permeability reservoir  fracture  quantitative  prediction  numerical simulation  spatial distribution
