| 摘 要： | 地震反演是当今最广泛应用于含油气储层预测的技术之一,取得了很多很好的预测效果,但也有失败的例子,达不到区分岩性和识别流体的目的。而本文介绍的建立在岩石物理建模和分析基础上的地震弹性反演,可将含油气储层预测由定性向(半)定量推进一步。根据岩石物理建模和正演扰动分析,可深刻理解岩石物性参数与地震弹性参数之间的内在关系,进而寻找储层岩性、物性和含油气性的敏感地震弹性参数,建立起理论岩石物理解释图版。岩石物理分析结果和所建立的岩石物理解释图版分别用以指导地震反演和反演结果的解释,实现油气储层分布预测和流体检测的目的。文中的含气砂岩分布预测实例研究应用结果表明,这种方法较叠后地震反演储层预测技术具有无可比拟的优越性,效果更佳,效率更高。

| Abstract: | Seismic inversion is one of the most widely used technologies for reservoir prediction.Many good results have been obtained but sometimes it fails to differentiate the lithologies and identify the fluids.However,seismic prestack elastic inversion based on rock physics modeling and analysis introduced in this paper is a significant method that can help seismic inversion and interpretation reach a new quantitative (or semi-quantitative) level from traditional qualitative interpretation.By doing rock physics m... |
