吐哈盆地火焰山断层下盘高陡构造油气勘探技术
On Technologies for Hydrocarbon Exploration in Steep Structure in Downthrow of Huoyanshan Fault in Turpan-Hami Basin
【摘要】 高陡构造资料处理采用层速度时深转换技术和射线深度偏移技术,将得到比较准确的构造成像剖面。从形成机制上分析了火焰山断层下盘构造褶皱变形特征,并通过建立正确的地质物理模式,确定反映凹凸陡断反射波阻,进行地震精细解释,然后变速成图。
【Abstract】 Using time depth conversion and depth migration technologies for data processing, more proper structural imaging profiles in steep structure were obtained. The author analyzed the fold and transformation of structure in lower block of Huoyanshan fault in terms of shaping mechanism, and developed a geophysical model. Based on these,the reflected impedance on steep fault was determined, detailed seismic interpretation was made, and then mapped out after velocity corrections.
