摘　　要：取提地震“三高”资料的新方法包括两个方面:采集方面,采用井下检波器在20m深的井中接收,所获记录明显提高了分辨率、保真度和同相轴的连续性;资料处理方面,采用“高分辨率高信噪比处理技术”,使井下接收记录经处理后的剖面主频高达80～100Hz。获得了高分辨率、高信噪比、高保真度的“三高”地震时间剖面。The new method for gaining 'Three High 'data in seismic exploration includes two aspects: One is the acquisition that resolution factor and fidelity as well as the continuity of lineups are obviously raised in the records obtained with the downhole detectors and received in the wells with depth of 20m The other is the data processing which seismic time section with 'Three High ',i. e. high resolution, high fidelity and high signal-to-noise ratio, has been obtained by use of 'The processing technigue with high resolution factor and high signal-to-noise ratio,' making the main frequency high up to 80～100Hz in the section after processing the records received in downhole.
