【摘要】 选用频率、振幅、连续性及内部反射结构 4个地震参数 ,对吐鲁番—哈密盆地SB(胜北 )地区中上侏罗统主要层系进行了地震相分析 ,作出了地震相平面分布图。经过综合解释 ,把地震相转换成了沉积相。该区中晚侏罗世主要发育冲积扇、泛滥平原、扇三角洲、辫状河三角洲及湖泊沉积。更多还原

【Abstract】 Seismic facies analysis of the Middle and Upper Jurassic formations in the Shengbei (SB)area of the Turpan-Hami basin was made on the four seismic parameters-frequency, amplitude, continuity and reflection structure. The map illustrating the seismic facies of the area was also drawn. The seismic facies has been transferred into the sedimentary facies after a comprehensive interpretation. It is shown that alluvial fan, flood plain, fan delta, braid river delta and lake were the main sedimentary facies in the SB area of the Turpan-Hami basin during middle and late Jurassic times.更多还原
