对松辽盆地可容空间变化规律的研究 ,有助于认识其生储盖组合特征和勘探潜力 .利用地震剖面解释并配合钻井和岩心等资料的分析 ,在松辽盆地中生代地层中识别出水下可容空间、陆上可容空间、盆地可容空间和潜在可容空间等 4种可容空间类型 .不同的可容空间其增加方式不同 :气候的由干→潮湿转变 ,湖海短期沟通增加水下可容空间 ;河流平衡剖面的迁移产生陆上可容空间 ;边界断层的活动或盆地整体坳陷产生盆地可容空间 .不同类型可容空间之间的对比关系 ,控制了盆地中生油层、储集层、盖层的发育情况及生储盖组合特征 .
The study on the spatial variation of accommodation space in Songliao Basin is helpful to understand the characteristics of the reservoir-cap assemblage and the exploration potential.Using the interpretation of seismic sections and the analysis of drilling and core data, the submarine formation in the Songliao Basin Tolerant space, land-tolerant space, basin-tolerant space and potential-tolerant space, etc. The different ways of adding space are different: the change of climate from dry to wet and the short-term communication between lake and sea increase Underwater can accommodate space; the balance of the river migration section produces land-tolerant space; the boundary fault activity or basin depression as a whole can produce the basin capacity space. The contrast between the different types of accommodation space, , The development of reservoirs and cap rocks, and the characteristics of reservoir-cap combination.
