摘要: 简要介绍了辽河大平房火山岩发育区的地质情况。在分析低频信号有利于火山岩下伏地层成像的理论基础上,以现有的地质认识为基础构建正演模型,模拟了不同频率的地震子波激发得到的单炮记录及偏移剖面。模拟结果表明,低频信号有利于辽河大平房火山岩发育区中深层成像,在下一步的勘探中应加强低频信号的保护。

Abstract: The geology of Dapingfang volcanic area in Liaohe depression is introduced briefly. Based on the analysis of the theory of low frequency signal which is beneficial to the image of underlying strata of volcanic rock, integrated with the present geologic knowledge, the forward model is developed for shot record and migration section obtained from different seismic wavelet. The modeling results indicate that low frequency signal is beneficial to the image of middle and deep strata, which should be protected in the further exploration in this area.

Key words: Liaohe oil field, volcanic rock, forward modeling, low frequency
