摘要
运用层序地层学原理和地震储集层预测技术相结合的方法,对大民屯凹陷西斜坡古近系岩性油藏进行预测,结果表明,边界断层在古近纪控制了大民屯凹陷西斜坡的形成,对体系域的空间展布也有重要的控制作用;大民屯凹陷古近纪可划分为3个二级层序,其中沉积层序SQ1生、储、盖配置关系好,具有优越的油气成藏条件;西斜坡沉积层序SQ1的低位体系域砂砾岩体是近年来岩性油藏勘探的重点目标;在层序研究的基础上,运用地震储集层预测技术预测砂砾岩体的空间分布,在勘探实践中获得了良好的效果。对同类岩性油藏的勘探具有一定的指导意义。
Sequence stratigraphy and seismic reservoir prediction technology are used to predict Paleogene-Neogene lithologic reservoirs in the western slope of Damintun depression.The result shows that,fault boundary controlled the forming of the western slope of Damintun in Paleogene-Neogene and also controlled the spatial distribution of system tract;the Paleogene-Neogene in Damintun can be divided into 3 secondary sequences,among which SQ1 has the best source-reservoir-caprock relation and advantageous oil and gas accumulation condition;the glutenite of SQ1 low-stand system tract is the main target of lithologic reservoir exploration in recent years;good exploration result has been achieved by using seismic prediction on the basis of sequence stratigraphy study.This method has a guiding sense to similar lithologic reservoir exploration.
