麻黄山西区块延安组河道砂体反射模式分析及应用
|
摘要
麻黄山西区块西部断裂复杂区以构造圈闭为主,东部稳定区以构造～岩性圈闭为主,由于延安组储层砂体薄,横向变化快,且二维地震资料品质差,储层预测较困难。为此运用地震地层学中储集体的地震反射结构原理,以二维模型分析为手段,通过对已知钻井地震反射结构的分析,总结出延安组河道砂体的反射模式,为该区延安组砂岩储层的综合预测奠定了地震技术基础。该成果在本区油气勘探开发井位建议中,发挥了重要的作用。
Mahuangshan western block includes complex fault zone in western and stable region of formation in eastern,the main traps of the former are the structural traps and the main traps of the latter are the structural-lithological traps,but the sand body of J1y formation is thin and changes quickly in lateral,and the quality of two-dimensional seismic data is poor,thus reservoir prediction of J1y formation is very difficult.Analyzing seismic reflection structure of the known well with seismic reflection structure principle of reservoir and two-dimensional model in seismic stratigraphy,and the reflection mode of channel sands for J1y formation is summarized,which is the seismic technology basis of comprehensive prediction for channel sands of J1y formation.Such achievements play the important role in exploration,development and well location suggestion of the bloc
