摘要
十万山盆地位于广西壮族自治区西南部,靠近中越边界。受多期构造活动的影响,该盆地深层地震地质条件复杂,断裂发育,地层产状高陡,资料品质低,成像效果差。近年来,随着对该区认识和研究的不断深入,以往采集资料品质已不能满足当前勘探任务的需要。应用宽线采集技术,可以优选激发炮点,同时利用相邻道的面元叠加信息,达到压制干扰的目的,从而提高叠加剖面的质量。宽线剖面与常规二维叠加剖面相比,表现出了有效反射信息更清晰,地质现象丰富,资料信噪比高的特点。
Shiwanshan Basin is located in the southwest of the Guangxi Zhuang Autonomous Region, close to Sino-- Vietnamese border. Influenced by multi--phase tectonic activities, its deep seismic geological condition is complex, its fault well--developed, its formation occurrence steep, its data of low quality and its imaging bad. With the con- tinuous understanding and research of the basin, former gathered data quality is not available for current exploration. Adopting wide line acquisition technology can optimize shot point and suppress disturbance by means of adjacent trace surface stacking information so as to improve the quality of stacked section. Compared with conventional 2D stacked section, wide line section presents the advantages of clearer effective reflecting information, more abundant geological appearance and better SNR data.
