摘要
济阳坳陷浅层气藏地震响应特征多样。由于真假亮点及非亮点气藏的存在,使得地震"亮点"技术存在局限,无法精确检测真亮点及非亮点气藏。为此,通过改进技术方法,探索了适合济阳坳陷浅层气藏勘探开发的地震识别技术。针对几种不同类型的含气层,以岩石物理分析为基础,进行正演模拟,分析不同类型含气层的叠前道集响应特征。以地震正演模拟为基础,计算弹性参数,筛选储层敏感参数。利用叠前地震直接反演方法,获取叠前地震敏感参数。应用叠前地震直接反演的敏感参数检测济阳坳陷浅层气藏,能够较好地检测出亮点气藏非亮点气藏,提高了浅层气藏的检测精度。
The seismic response of shallow gas reservoir in Jiyang Depression is variety. As the existence of true or false bright spot and non-bright spot gas reservoirs,the seismic "bright spot"technique has limitations,it can not accurately detect true bright spot and non-bright spot gas reservoirs. Consequently,through improving technology and methods,the seismic recognition technology suitable shallow gas reservoir in Jiyang Depression exploration was explored. For several different types of gas layer,based on petrophysical analysis,simulation analysis,analysised different types of gas layer prestack gathers response characteristics are carried out forward. On this base,calculating the elastic parameters,filtering reservoir sensitive parameters,the pre-stack seismic sensitive parameters were obtained using pre-stack seismic direct inversion method. Shallow gas reservoirs in Jiyang Depression using pre-stack seismic direct inversion sensitivity parameters are detected,the bright spot reservoir and non-bright spot reservoir can be better detected,improving the detection accuracy of shallow gas reservoirs.
