地震岩石物理是油藏储层描述和地下孔隙流体检测的重要技术之一。在岩石物理模型中,通常将速度与孔隙度和黏土含量等矿物成分结合起来,形成了用孔隙度和岩相地震分析的关键部分,甚至在地震孔隙流体分析中也需要速度。然而黏土含量对速度的影响又非常大,因此本文就油气储层中的砂岩、泥质砂岩和砂质泥岩中黏土含量对速度影响做出分析。
Seismic rock physics is one of the most important technologies for reservoir reservoir description and underground pore fluid testing. In petrophysical models, velocity and mineral composition such as porosity and clay content are often combined to form the key part of porosity and facies seismic analyzes, even where seismic pore fluid analysis requires velocity. However, the influence of clay content on the velocity is very large. Therefore, this paper analyzes the influence of the clay content on the velocity in the sandstone, shaly sandstone and sandy mudstone of oil and gas reservoirs.
