将高分辨率层序地层学和地震储层预测技术有机结合,并充分发挥这2种技术的优势,可为岩性地层油气藏勘探研究提供行之有效的方案.在高柳地区东营组岩性地层油藏勘探中应用了该方法.首先以多级次基准面旋回为参照面进行高分辨率层序地层研究,建立研究区层序地层划分方案和层序地层格架,将东营组划分为1个二级层序,并进一步划分出4个三级层序;然后应用高分辨率地震资料,在高分辨率层序地层格架约束下,采用储层地震反演技术,追踪识别4个层序旋回内的有效砂体(砂层组)共28个,为研究区岩性地层油气藏勘探提供了有利的决策依据.
將高分辨率層序地層學和地震儲層預測技術有機結閤,併充分髮揮這2種技術的優勢,可為巖性地層油氣藏勘探研究提供行之有效的方案.在高柳地區東營組巖性地層油藏勘探中應用瞭該方法.首先以多級次基準麵鏇迴為參照麵進行高分辨率層序地層研究,建立研究區層序地層劃分方案和層序地層格架,將東營組劃分為1箇二級層序,併進一步劃分齣4箇三級層序;然後應用高分辨率地震資料,在高分辨率層序地層格架約束下,採用儲層地震反縯技術,追蹤識彆4箇層序鏇迴內的有效砂體(砂層組)共28箇,為研究區巖性地層油氣藏勘探提供瞭有利的決策依據.

Based on the high resolution sequence stratigraphy and the seismic reservoir prediction techniques,a method of the lithological reservoirs exploration is proposed and then applied to Gaoliu area.The divided solution of sequence and the sequence stratigraphical framework are established by the study of high-resolution sequence stratigraphy based on high level cycle as reference level.The Dongying Formation is divided into one long-term level cycle and four medium-term level cycles.Using the seismic reservoir inversion technique which is constrained by the high-resolution sequence stratigraphic framework,twenty eight individual sand bodies in the four sequences are identified,which provides favorable evidence for the lithological reservoir exploration.
