摘要:
 海拉尔盆地呼南次凹南一段储层岩性复杂，开发难度大。为明确地应力分布情况，以区块地质、构造、沉积特征为基础，结合室内实验结果，采用非均质连续介质力学模型处理断层，建立了基于有限元的复杂岩性储层三维地应力模型，模拟了该区块地应力分布情况，分析了区块地应力场空间分布规律。研究结果表明，深度、断层是影响地层水平主应力分布的重要因素，深度增加，地层水平主应力增加；断层附近存在应力集中区域，极大影响水平主应力。应用三维地应力数值模型计算不同井相应深度处的地应力大小，与实例井测试压裂解释应力结果符合率90%以上。该研究可为海拉尔盆地复杂岩性储层压裂设计提供指导，为区块高效开发奠定基础。
Abstract:
 Reservoirs in the southern member 1 in the Hunan secondary sag in the Hailar Basin are complex and difficult to be developed. Based on the regional geology, structure and sedimentation and laboratory experimental results, and using a mechanical model of heterogeneous continuous media to deal with faults, a 3D geostress model was established to simulate the geostress and analyze its spatial distribution in the complex lithologic reservoirs. The results show that depth and faults are important factors that affect the distribution of the horizontal principal stress; as the depth increases, the horizontal principal stress increases; the stress is concentrated near the faults, and greatly affects the horizontal principal stress. The geostresses modeled by the 3D numerical model at different depths in different wells are consistent with the geostresses from fracturing interpretation by over 90%. This study is helpful to designing reservoir fracturing stimulation for complex lithologic reservoirs in Hailar Basin. It lays a foundation for efficient regional development.
