【摘要】 中古生界地震资料一直是地震采集的难点,多年来一直在进行中古生界地震资料采集方法研究和攻关。中古生界勘探由于地下复杂,且激发和接收条件较差,导致资料信噪比低,品质较差。在分析影响资料品质原因的基础上,对中古生界野外采集方法进行了研究,分析了炮间距、排列长度、覆盖次数和宽线采集方法对中古生界成像和信噪比的影响。更多还原

【Abstract】 It was very difficult for collecting Mesozoic-Paleozoic seismic data,methods for Mesozoic- Paleozoic seismic data acquisition have been researched and developed for years. Because in Mesozoic-Paleozoic strata there existed complex downhole conditions,excitation and receiving conditions were poor,therefore signal-noise ratio was low in data acquisition with poor quality. On the basis of analyzing causes of influencing the data quality,the effects of the methods for Mesozoic-Paleozoic seismic data acquisition are studied,shot intervals its array length,coverage and way of wide-line data acquisition on the imaging and signal-noise ratio in Mesozoic-Paleozoic strata are analyzed.更多还原
