低信噪比地区地震采集激发技术探讨
摘要
由于受地表、近地表、地下复杂条件的影响,低信噪比地区干扰波发育,地震资料品质差。该类地区地震资料信噪比的提高和改善面临着诸多技术难题。地震激发技术是提高低信噪比地区地震资料信噪比的一项关键技术。为此,对地震激发技术进行了理论与实际相结合的探讨与分析。首先,通过多种方法综合的表层结构调查弄清复杂地表的表层结构,以帮助选取合适的激发岩性和激发参数;其次,利用基于地形与表层结构的动态设计技术设计井深;再次,依据地震波的能量、频率和信噪比的好坏优选激发药量;然后,利用基于能量和观测属性的激发点位选择方法选择激发点位;最后,采用组合激发和闷井技术提高激发效果。上述地震激发技术和配套工艺的应用,有助于提高低信噪比地区的地震资料品质。
