利用地震亮点反射进行气藏直接检测在国内外天然气勘探中有许多成功的实例并且带来了良好的勘探效益。但由于地下地质情况非常复杂,即使在墨西哥湾“亮点”勘探成熟地区“亮点”勘探也曾遭受过失败。纵向序列岩石物理学特点、产层埋深和地震资料质量等是能否对油气藏进行地震直接检测的影响因素。在充分研究了北大港浅层纵向序列岩石物理特点的基础上,以地震地质模型为指导,利用地震亮点反射进行了气藏直接检测并在具有高质量地震资料的地区取得了较好的应用效果。

There are many successful examples on applying the seismic bright spot reflection to make a direct detection for the gas reservoir both domestic and abroad, and this has really brought good exploration benefit. However, with the complicated underground situation the bright spot exploration once failed even in such a mature area for bright spot exploration like Gulf Mexico. In the author’s opinion whether an oil and gas field can be conducted with reservoir seismic detection mainly dues to the vertical sequelea.
