摘要
超低渗透油藏之所以能够实现经济、有效开发与储层中天然裂缝发育这一本质特征密切相关。常规的地质建模忽略了天然裂缝的影响，降低了开发预测和方案优化结果的可靠性。本次研究以构造曲率法为主体，结合有限元法所得到的构造裂缝分布规律以及综合地质分析所得到的天然裂缝特征参数．利用RMS软件中的裂缝模块定量化加载天然裂缝的方法建立裂缝性地质模型。在应用数值模拟进行历史拟合时，应用调整裂缝几何参数与平面分布规律等方法．改变了过去对基质属性调整的一些不合理做法，较好地解决了传统方法对含水率和注水量拟合效果不好的历史难题．
The ultra-low permeability reservoir has been able to achieve economic, efficient development and reservoir development of the essential characteristics of natural fractures is closely related. Conventional geological modeling ignores the impact of natural cracks and reduce the development program of forecasting and optimization of reliability of the resuhs. This study to construct the curvature method as the main body, combined with finite element method, the resulting distribution of structural cracks, as well as comprehensive geological analysis of natural fracture characteristic parameters obtained using the RMS software, cracks in the module loaded quantitative methods of natural cracks in the establishment of cracks geological model. In the application of numerical simulation history matching, when applied to adjust the geometric parameters and the crack plane distribution methods, changing the matrix properties of the past to adjust some of the unreasonable practices, a better solution of the traditional methods of moisture content and water injection fitting results bad historical problems.
