【摘要】 大庆长垣扶余油层尚有大量的油气资源量未被开发,是大庆油田重要的后备储量资源,也是大庆建设百年油田主要的勘探与开发领域,其储层砂体为河流-三角洲环境沉积,砂体厚度横向变化较快,属低孔、低渗储层,河道砂体不易预测与识别,针对这一问题本文在S5井区进行了地震储层预测技术的研究。本次研究采用了沿参考标准层拉平解释技术、拾取最佳时窗子体技术、地震多属性融合分析技术及井震结合沉积相刻画技术等几项关键技术,对扶余油层的河道砂体进行预测,取得了良好的效果.曲流河点坝得到了清晰的刻画,并结合钻井资料分析,进行了沉积相精细刻画,为该区的寻找薄层岩性油气藏提供了可靠的依据。更多还原

【Abstract】 There is still a large amount of hydrocarbon resource undeveloped in Fuyu resource for Daqing Oilfield,also is major exploration and development domain for Daqing.Its reservoir sand body is distributary channel deposit and fluvial-deltic environment Sand body thickness varies fast horizontally.The reservoirs have low porosity and low permeability.The channel sand body is hard to predict and identify.Aiming at this problem,seismic technology research is carried out in Fuyu reservoirs.The technologies of flatten interpretation along reference standard horizon,Picking up best window of body,Integration of multi-attribute analysis of seismic and Well seismic combined sedimentary facies characterization are adoped,which predict Fuyu oil layer of river sand and has achieved good results.Meandering river point bar has been a clear characterization,and In conjunction with drilling data analysis,carried out detailed characterization of sedimentary facies.This study provides the reliable evidence for searching the thin-layer lithologic reservoir.更多还原
