摘要:

东营凹陷博兴洼陷古近系沙四段滨浅湖滩坝砂岩油藏是岩性油藏的一种重要类型。滩坝砂岩储层具有埋藏深、横向变化大、储层单层厚度较薄的特点,充分利用地震信息,结合地质和钻井资料,研究其储层预测技术具有较大的意义。通过多年的勘探实践,胜利油田目前已初步形成了一套针对滩坝砂岩储层预测技术,主要为古沉积环境恢复技术、正演模型技术、地震属性分析技术和基于地质目标的反演技术,在博兴洼陷古近系沙四段滨浅湖滩坝砂岩油藏勘探开发中取得了良好的效果。

Abstract:

Featuring in deep burial depth,large lateral variation,and small single layer thickness,the beach bar sand reservoirs in the 4th member of Shahejie Formation is an important type of lithological deposits.Integrated utilization of seismic,geology and drilling data is important to the prediction of this kind of reservoirs.After years of exploration practices,a series of techniques,including palaeosedimentary environment reconstruction,forward modeling,seismic attribute analysis and geologic target-oriented inversion,has taken a complete shape in Shengli Oilfield by aiming at beach bar reservoir prediction.These techniques are employed in the exploration of the beach bar sand reservoirs in Boxing subsag of Dongying sag and the results are quite encouraging.

Key words: shore-shallow lake facies, beach bar sands, palaeosedimentary environment reconstruction, seismic attribute analysis, reservoir prediction, Dongying sag
