摘　　要：在青藏盆地油气勘探中采用宽线观测方式,压制噪声,提高资料信噪比,所得剖面较以往剖面的成像品质、可解释性有很大提升。特别是高覆盖、宽线观测方式有利于提高弱反射信号的信噪比,改善叠加剖面的成像效果;宽线观测和横向大组合接收,有助于提高叠加成像效果。宽线观测方式成为整体把握青藏盆地构造格架,评价构造保存条件的重要依据。The application of broad line observation method in oil-gas exploration of Qinghai-Tibet Basin has a better result in suppressing noise,improving imaging quality and enhancing interpretability.High covering and broad line observation method helps to lift signal-to-noise ratio of the weak reflected signal and improve image effect of the stacked section.Broad line observation and big horizontal combination receiving are conducive to improving stack imaging result.Therefore,broad line observation method is important in grasping wholly the tectonic framework of Qinghai-Tibet Basin and evaluating structure preservation condition.
