滩海地区地震数据驱动的油藏评价及实践
|
摘要
针对滩海地区油藏评价的特殊性和资料的局限性,提出以地震数据为依托的油藏评价一体化研究方法与流程。以地震数据为约束,综合应用层序地层格架厘定、三维构造精细解释、地震属性分析、随机模拟地震反演、地质建模、数值模拟等技术,将构造解释和随机模拟地震反演结果作为三维定量地质模型的输入,通过动态数据的修正,建立一体化预测模型。在大港滩海张东开发区的应用实践取得了较好的效果,可为类似地区的油藏评价提供借鉴。
According to characteristics and request of reservoir evaluation, as well as the limitation of information in beach area, the method and workflow of integrated reservoir evaluation driven by seismic data is put forward in this paper. Taking the seismic data as restriction, this method makes combination of a set of technology including setting sequence stratigraphic frame, 3D fine structure interpretation, seismic attribute analysis, stochastic simulation seismic inversion, geological modeling based on seismic data, and numerical simulation. The results of structure interpretation and stochastic simulation seismic inversion are the input of 3D quantitative geological model. The integrated predictive model is set through revising by dynamical data. The application to Zhangdong development zone in beach area of Dagang Oilfield generates a better effect. It also provides the reference for the analogical area in reservoir evaluation.
