摘要
基于构造层序与基准面分析原理,利用高分辨地震、测井、岩相等资料重点研究了白垩纪松辽湖盆各体系域的沉积特征。应用多种地球物理手段在体系域内进行的储集层预测、岩性地层圈闭分析及勘探实际表明,本区发育在湖扩展域和高位域的三角洲前缘河口坝、远砂坝以及湖底扇等各类砂体,对形成隐蔽油气藏最为有利。大布苏地区勘探实例可以作为隐蔽油藏勘探的典型,对广阔的松南西部斜坡区下步勘探具有借鉴意义。
On the basis of the principles of tectonic and base-level analysis, the depositional characteristics of the Cretaceous system tracts in Songliao Continental Basin was investigated by using high-resolution seismic sections, log curves and lithofacies data. The reservoir prediction, litho-stratigrophic trap analysis with several geophysical methods and the practical exploration show that the sandstones distributed in channel of delta, mouth bar, distal bar in the delta front belt and lake-floor fan are favorable for oil bearing. The exploration for oil and gas in Dabusu area is a typical example for exploration of subtle reservoir. It has a great significance for oil and gas exploration in the western slope of Songliao Basin.
