NOTE: The data processing procedures include: synthetic seismogram calculation, synthetic-real seismic trace correlation, and geo-body extraction. Below are the step-by-step details of each procedure.
1. Calculation of Synthetic Seismogram

	<li>Calculate the acoustic impedance at each interval of the down-well logging curve. 
	NOTE: Acoustic impedance is the product of &#39;seismic wave velocities&#39; and &#39;density&#39; (&#961;*&#957;)). The data are often averaged to sampling ...

在这里我们展示 2 种方法说明埋的玄武质火山; 水暖系统的结构与形态一个是不透明度渲染，其他时间是切片。
不透明度渲染方法是适合有连续和包围地层水平界面附近的土力工程处机构。使用此方法，可以提取三维形态的岩浆裂片。通常情况下，流向应沿长轴的岩浆裂片。它也是重要的表面的视野有高反射系数 (R0)。如果R0在界面太低，口译员?...

大多数工业沉积盆地地震成像项目旨在探讨油气藏。近年来，油气勘探已扩展到包含大量的火成岩，因为许多火山盆地有可观的油、 气藏的盆地。然而，由于火山盆地火成岩的接口，地震数据处理提出了一系列的挑战各种入侵，如减少的能量传输、 固有衰减、 干扰效应、 折射和散射1所致。因此，油田公司正在努力减少这类"负面影响"地震成像2，，34。
火成岩体沉积盆地内的方便地识别所包围的岩石1，，56大的声阻抗对比两个二维或三维地震反射成像。这种方法可以提供纵向和横向结构的火山水暖系统7，8，9，10，，1112，13的壮观画面。然而，成像地下火山的策略是非常不同于石油和天然气勘探8，，1415。这限制了工业中的地震资料研究地下火山，除了几个成功的案例10，，1516使用。在本文中，我们报告地震数据处理中，这定制的地下火山解释的详细的的过程。我们处理两个地震的多维数据集，TZ47 和 YM2 (图 1)，以显示如何可视化隐伏火成岩体在塔里木洪水玄武岩17。

管道系统的结构与形态可以提供关键信息的爆发率和风格的玄武岩熔岩。最有力的方式来研究地下地质机构是使用工业 3D 反射地震成像。然而，图像地下火山的战略是非常不同于石油和天然气储层。在此研究中，我们处理地震数据多维数据集从塔里木盆地，中国北方，来说明如何可视化窗台通过不透明度渲染技术以及如何通过时间切片图像的管道。在第一种情况下，我们分离探针由地震层位标记之间窗台联系人和装箱地层，应用不透明度渲染技术来提取门槛从地震的多维数据集。由此产生的详细的窗台形态显示流动方向是从穹顶中心到边缘。在第二次地震多维数据集，我们使用时间切片图像的管道，对应于标记内包围的岩石的不连续性。时间片在不同深度获得一套表明塔里木溢流玄武岩喷发从中央的火山喷发，美联储通过单独的管样管道。

我们演示技术通过将它们应用到 2 种类型的火成岩体、 水平梁和垂直火山管道上文所述的用途。采用不透明的渲染技术，进行萃取的窗台，利用切片技术进行解释的火山通道。
