以松辽盆地西斜坡月亮泡地区姚家组萨尔图油层和长垣安达地区青山口组高台子油层为例,针对不同地质条件下砂体识别与岩性油气藏勘探问题,采用薄储层识别的频谱分解技术和楔状、非平卧地层储层识别的地层切片技术,很好地刻画了西斜坡三角洲前缘水下分流河道砂体及长垣地区三角洲前缘席状砂和河口坝等砂体的展布,指导了这2个地区沉积微相研究及岩性油气藏勘探。研究表明,地震沉积学相关技术是解决松辽盆地不同地质条件下砂体识别及岩性油气藏勘探的有效技术手段。该思路和方法也可借鉴到类似盆地、类似地质背景下的岩性油气藏勘探中。

In order to identify the sand bodies and find lithologic reservoirs under different geological settings in the western slope and placanticline area of Songliao Basin, the study was taken based on the data of Saertuoil layer of Yaojia I;ormalion in Yueliangpao area in lhe western slope and Gaotaizi oil layer of Qingshankou Formation in Anda area in the plaeantieline. The lechniques of spectrum decomposilion and strata slice were adopted to describe tile dislribulion of subaqueous distribulary channel sand bodies in della front in the western slope and the geometry of sand bodies of sheet sand and river moulh bar in de, ha front in the plaeantieline area. The results practieally guide the study on sedimentary, microfacies and lithologic reservoir exploration. The research shows that the techniques correlated with seismic sedimentology are, reliable methods to solve the identifieation of sand bodies and prediction of lithologic reservoirs in different geological settings in Songliao Basin.
