基于岩石物理模型和谱分解的储层描述技术

摘要
横波品质因子的倒数与剪切模量一频散有关,由此可以建立横波衰减的估算方法。非固结砂岩的地震响应研究表明泊松比参数与低有效应力的砂岩模型参数有关。不同压力下岩石的弹性参数变化研究证实随着有效压力的增加,孔隙之间的喉道缩小。这使得纵横比小的柔顺孔隙关闭。从而降低孔隙度。借助模型技术,可以利用孔隙介质中粘滞流体对地震波传播速度的影响预测地震波传播速度,降低反演结果的不确定性。利用岩石物性研究地震振幅响应,提供了一种更可靠的岩性、孔隙度、岩石纹理、孔隙流体和厚度地震预测,岩石物理模型驱动的地震反演技术可以实现直接反演孔隙度。地震波衰减机制和测量方法研究表明,在孔隙和渗透性碎屑岩中,流体运动是衰减的主要机制。深水环境下的流体模型可以通过地震和井资料的地质统计反演方法来建立。地震资料谱分解技术已在裂缝发育方向和裂缝间距的检测中得到了实际应用。
S-wave inverse quality factor is related to the shear-modulus versus frequency dispersion, which can be used to develop method for estimation of S-wave attenuation. Seismic responses of unconsolidated sands indicate that Poisson's ratio is related to the parameters of sand with low effective stress. An increasing effective pressure gradually reduces the throats between pore. It forces closure of compliant pores with low aspect ratio and reduces porosity. With the help of model techniques, we can determine seismic velocity in porous media by accounting for viscous fluid effects on wave propagation. The calibration of rock properties from well logs and core information to the seismic response provides a more reliable seismic prediction in terms of lithology. porosity, texture, pore fluid, and thickness. Porosity can be inverted directly by rock physics model-driven seismic inversion. Direct measurement of seismic attenuation ascertains that fluid motion is a primary mechanism in porous, permeable elastics. Flow simulation model can be determined using geostatistical inversion of seismic and borehole data Spectral decomposition has been successfully applied in i-dentification of fracture spacing and orientation.
