摘　　要：裂缝识别在碳酸盐岩储层研究中具有非常重要的现实意义。文章在探讨裂缝识别方法及构造应力场模拟原理的基础上,以珠江口盆地东沙隆起的流花11-1生物礁油田为靶区,通过叠前三维地震反演,得到空变的弹性参数,构建精细的非均质力学模型,密切结合应力场数值模拟技术和地震反演技术。与常规构造应力场模拟相比,叠前构造应力场模拟更加合理地考虑到叠前弹性参数,从而能更精确地进行碳酸盐岩储层构造裂缝的检测,有较好的应用效果。It is important to identify fractures in carbonate reservoir. Based on the method to identify fracture and the mathematic principle of numerical simulation, the algorithm and process of fracture detection applied in pre-stack 3D seismic data were designed and realized using numerical simulation of tectonic stress field. For target areas in LHll-1 reef reservoir oilfield in the Dongsha Uplift, Pearl River Mouth Basin, the parameters of pre-stack 3D seismic inversion were closely combined with numerical simulation of tectonic stress field and seismic inversion to construct fine heterogeneous mechanical model. Because of the pre-stack elastic parameter was considered in heterogeneous model, so it is more reasonable and more accurate than homogenous model in detecting fracture in carbonate reservoir
