| 摘 要： | 通过对塔里木盆地巴楚至塔中的12 s深反射地震资料的分析、处理表明,在南北方向上,由和3井经和田1井至和4井基底由北向南逐步抬升,和4井向南基底变深;东西向,巴楚隆起基底较浅,到塔中变深;通过处理可以发现,除了通常可以看到的T4-T9各层反射结构外,在基底以下的深层,还能看到有效的反射;经初步解释和地质分析认为,所处理剖面同相轴连续性好,信噪比较高,归位准确,深层反射信息可靠,剖面所反映的构造形态清楚,规模较大,基本落实了所部署测线工区的地下构造,而且还揭示了一些以前尚未认识到的构造或构造显示,丰富了该区构造特征和构造演化的认识。

| Abstract: | The analysis and processing of 12-second deep reflection seismic data obtained from Bachu to Tazhong in Tarim basin show that,in NS direction,the basement is gradually uplifted from He-3 well through Hetian-1 well to He-4 well,with the basement becoming deeper from He-4 well southwards;in EW direction,the basement of Bachu uplift is relatively shallow,and becomes deeper at Tazhong.Through processing,the authors have found that,besides commonly seen reflection structures of T4-T9 layers,effective reflection ... |
