摘要
塔里木英买2区块裂缝型油藏具有孔隙空间结构复杂、非均质性强等特征,为储层描述和地质建模带来极大的不确定性。为增加稳定性,在裂缝预测方面,采用全局优化扫描算法计算高精度曲率属性,完成裂缝定性预测,并以此为约束,综合静态解释成果和生产动态信息,首次实现裂缝叠后定量预测;引入离散裂缝网格建模技术,利用Petrel地质建模软件最终建立反映裂缝型油藏特征的双孔介质模型,为油藏数值模拟和开发评价提供了依据。
The Yingmai- 2 fractured oil reservoir in Tarim has the features of complicated porous spaces and strong heterogeneity, imposing extreme uncertainty to reservoir description and geologic modeling. To increase the stability of fracture prediction,high accuracy curvature attributes are calculated by use of global optimization scanning algorithm to deliver the qualitative prediction of fracture,as constrained by which,qualitative post- stack prediction of fracture is realized for the first time in combination with the static interpretation results and production performance information. By introduction of modeling of discrete fracture network and use of Petrel geological modeling software,the dual porosity medium model has been modeled finally along with the fractured oil reservoir characterized,providing basis for oil reservoir numerical simulation and development evaluation.
