摘要
为了对无岩心和无露头地区进行油气勘探和油气藏描述，选用频率、振幅、连续性及内部反射结构等４ 个地震参数，对吐哈盆地 Ｓ Ｂ 地区西山窑组上部地层进行了地震相分析，并作出了地震相的平面分布图。经过地震解释，再把地震相转化为沉积相，结果表明：该区西山窑组时期主要发育辫状河三角洲及浅湖～深湖相沉积。
Seismic facies analysis of upper Xishanyao Fm. In SB area of Turpan-Hami basin was made on the four seismic parameters---frequency,amplitude, continuity and reflection structure.The map of seismic facies in the area was also drawn.The seismic facies has been transferred into sedimentary facies after interpretation.It is shown that braid river delta , mere and aphytal are main sedimentary facies in the study area during late Xishanyao period,Jurassic.
