陆相断陷盆地复杂地质模型建立与正演模拟
|
摘要
仿Marmousi模型论证地震方法的思路,本文以济阳断陷盆地多期构造运动形成的构造格局和六种典型构造模式为研究对象,把胜利油田典型的地质特点浓缩到一个模型中,即陆相断陷盆地复杂地质模型,简称“胜利油田典型模型”。文中论述了建立模型的具体过程和方法,即先建构造模型,再建地层、岩性模型;然后介绍了胜利油田典型模型的正演模拟及其数据体在研究叠前深度偏移方法和观测系统设计方面的应用。应用效果表明此方法具有良好的应用前景。
Using similar thought as Marmousi model for demonstration of seismic approach and taking structural configuration, formed by multi-period tectonic movement and 6 typical structural models in Jiyang fault depression basin as studied objects, the paper compressed the typical geologic feature of Shengli Oilfield into one model, i.e. complex geologic model in continental fault depression basin, simply called "Shengli Oilfield typical model". The paper expounded the concrete model-building process and method, i.e. first to create structural models and then to build up stratigraphic and lithologic models. The paper also introduced the forward simulation of Shenli Oilfield typical model and application of their data volume to study prestack depth migration and design of geometry. The application effects showed the method has good application prospect.
