【摘要】 准噶尔盆地腹部莫索湾沙漠区侏罗系煤下储层三工河组是主要油气高产层系之一,主要发育构造-岩性复合圈闭,目的层受地表沙漠和西山窑强煤层影响,地震资料信噪比、分辨率低,反射能量弱,储层薄、横向变化快.将地质与地球物理技术有机结合,采用面向目标识别处理技术、岩石物理分析技术、叠前储层预测和流体检测技术,取得了丰富的地震地质结果,为该地区的储量升级提供了保障.更多还原

【Abstract】 Sangonghe Formation below Jurassic coal in Mosuowan desert of central Junggar Basin is one of high production strata,in which structure-lithology composite traps develop.Because of influence of surface desert and Jurassic coal on seismic data near the target layer,signal-to-noise ratio and resolution are low,and reflection energy is weak.The reservoir is thin and its thickness changes quickly in lateral.Rich seismic and geology data are achieved for pre-stack reservoir prediction and fluid identification by combining geology with geophysics and using object identification oriented processing technique and rock physics analysis technique,which provide support for reserves upgrade in this area.更多还原
