【摘要】 基于南海北部中生界勘探面临的复杂地震地质条件,为改善该海域地震勘探难点区的资料质量,本文设计出6400in3的Bolt长寿枪震源,其特点是震源子波输出峰值和低频段能量得到加强,低频端由8Hz拓展到6Hz。通过对野外试验及实际海上地震勘探数据采集的效果的分析、对比,证实所设计的震源适用于南海北部中生界的油气资源探测。更多还原

【Abstract】 Based on the exploration of Mesozoic group in the northern South China Sea facing complex seismic geological condition,in order to improve the marine seismic exploration difficulty area data quality,this paper designs the 6400in3 Bolt long-life air-gun array,its characteristic is the source wavelet output peak and low frequency energy are strengthened,also the low frequency direction edge is expanded from 8Hz to 6Hz.After the field test and actual marine seismic exploration data acquisition effect analysis and contrast,It confirms the designed source applied to the Mesozoic group in the northern South China Sea oil and gas resources exploration.更多还原
