【摘要】 真联地区具有良好的生、储、盖条件和组合关系,但地下断块破碎、构造复杂,地震资料难以准确成像。通过建立复杂断块模型进行适应性分析,并在叠前精细处理的基础上,开展了偏移速度建模及逆时偏移处理技术应用等方面的研究,在真联高精度三维等多块三维上实施取得了比较明显的效果。更多还原

【Abstract】 There are good conditions on sources,reservoirs,and cap rocks and combination relationship in Zhenlian area. Because of fractured block and complex structure,it is difficult to obtain exact images by seismic data. By building up a complex fault- block model,it was carried out the adaptation of RTM( reverse- time migration) technology. On the basis of the prestack fine processing,the studies were mainly focused on several aspects such as migration velocity modeling,RTM processing technology,and so on. The RTM technology was applied in several high- precision 3D seismic areas represented by Zhenlian area and obvious effects were obtained.更多还原
