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。
In order to carry out oil-gas exploration and reservoir description for non-core and out-of-area, seismic facies analysis was carried out on the upper strata of Xishanyao formation in S B area of Turpan-Hami basin by selecting four seismic parameters such as frequency, amplitude, continuity and internal reflection structure , And made a seismic facies plane distribution. After seismic interpretation, the seismic facies was transformed into sedimentary facies. The results show that the braided river delta and shallow lacustrine to deep lacustrine facies are mainly developed during the Xishanyao Formation.
