地震正演模型应用(Ⅰ):用叠后地震正演模拟方法精确解释东河砂岩尖灭点OA北大核心CSCD
Applied seismic forward modeling (part Ⅰ ): Accurate interpretation of the Donghe sandstone pinchout by post-stack seismic forward modeling
叠后正演模拟不仅能更好地解释平缓构造背景下的地震数据,而且有助于描述地震资料无法分辨的地质体.东河砂岩是塔里木盆地已知的储集层,横向展布不均匀,由于地震分辨率的限制,很难准确描述东河砂岩的空间展布.用叠后地震正演模拟方法研究东河砂岩尖灭点分布,发现合成地震振幅能量首先增强,然后衰减,其中还存在地层上拉和假倾角现象.这些特征有助于对东河砂岩尖灭点进行地震解释.
Post-stack seismic forward modeling can be used to better interpret seismic data in gently dipping geologies andcharacterize geological body of even sub-seismic resolution by revealing the characteristic seismic responses. The Donghesandstone of the Tarim Basin is a known oil reservoir with widespread but irregular lateral distribution. Because of the limitof the seismic resolution, it is difficult to delineate the spatial distribution of the sandstone. Post…查看全部>>
