松辽盆地火山岩发育区数值模拟参数设计
|
摘要
松辽盆地火山岩埋藏较深,构造复杂,地震资料信噪比偏低,且成像精度低,因此很难进行火山岩储层预测。为了提高火山岩预测精度,本文利用波动方程的数值模拟技术,对观测系统相关参数进行分析和论证。文中从排列长度、炮间距、观测方式、偏移孔径等参数的优化入手,设计出合理观测系统,并通过实际火山岩正演模型的数值模拟,清楚地识别出火山岩发育带,从而为实际火山岩分布区的波场特征研究提供了佐证。
The volcanic rock in Songliao Basin is characteristics of deep buried depth and complex structure, resulted in poorer S/N ratio of seismic data and lower imaging precision, which bought about difficulty in prediction of volcanic rock reservoir. In order to improve the predicting precision of volcanic rock, we used numeric modeling technique of wave equation to analyze and demonstrate the relevant parameters of geometry. The paper highlighted the optimizing the spread length, offset, surveying pattern and migration aperture, which designed reasonable geometry and clearly recognized development zone of volcanic rock by numeric simulation of forward model of practical volcanic rock, gave proof of study on wavefield characters in practical volcanic rock zone.
