吉林柳河盆地沉积特征与油气勘探前景
|
摘要
野外地质调查、地震剖面精细解释及取样测试分析结果显示,柳河盆地早期主要受控于西北边缘断裂,后期主要受控于东南边缘断裂,整体上构成了早期以西北物源供给为主、后期以东南物源供给为主、沉积中心逐渐向盆地东北部退缩迁移的半深湖-扇三角洲或半深湖-湖底扇-扇三角洲沉积体系;构成了具有中-好烃源岩的自生自储和下生上储2种生储盖组合;并在断陷中东部区带,形成了有利的岩性油气成藏条件,具有一定的油气勘探前景。
Through field geological survey,detailed seismic interpretation and sample analysis,it shows that the early stage of Liuhe Basin is mainly controlled by the northwestern marginal fault,but by the southeastern marginal fault later. On the whole,it constitutes a semi-deep lake-fan delta or semi-deep lake-lake floor fan-fan delta sedimentary system,which was dominated by the northwestern provenance in the early stage,and the southeastern provenance was mainly in the later stage,with the sedimentary center gradually retreating to the northeast of the basin. There developed two kinds of source-reservoir-cap rock combinations with medium to good source rocks,which are self-sourcing and self-reservoiring combination,lower-sourcing and upper-reservoiring combination. The central-eastern zone of the fault depression is favorable for lithologic hydrocarbon accumulation,which has certain prospect for oil and gas exploration.
