【摘要】 准噶尔盆地石西凸起侏罗系八道湾组具很大勘探潜力,现有地震资料对低幅度构造背斜圈闭不能进行有效识别.为满足圈闭识别需要,在不同解释方案基础上,利用SeisModTM波动方程正演模拟软件构建3种地质模型,正演模拟出不同地层构造模式下地震响应特征.通过对正演模拟结果对比分析,为背斜圈闭解释方案提供理论依据,对该区侏罗系八道湾组油气勘探提供有效技术手段.更多还原

【Abstract】 The Badaowan formation of Jurassic is high potential for exporation in shixi uplift,Junggar Basin.The bad quality of now available seismic data has some negative effect on identification of low amplitude anticlinal trap.For meeting the need of identification of trap,the SeisModTM software is used to building there geologic models,and obtains different seismic response of the forward modeling based on wave equation.The results of the forward modeling provide theoretical base of interpretation scheme,which provides an effective technical method for exploration activity of the Badaowan formation of Jurassic in the area.更多还原
