大民屯凹陷西斜坡Es_4段岩性油气藏整体解剖
|
摘要
本文针对大民屯凹陷构造复杂、薄互层储层横向变化快等特殊地质条件,应用精细地质分析、属性分析、地震相、测井相、沉积相分析、多井约束反演等技术对大民屯凹陷西斜坡Es4段岩性油气藏进行了整体解剖,有效地识别了地下复杂地质构造及地震异常反射体,综合岩性解释、定量预测和描述了单层砂岩空间分布及变化规律,在油田的勘探开发中取得了良好的效果。
In accordance with the special geologic conditions in Damingtun sag,such as complex structure and rapid lateral change of thin and interbedded reservoir,the paper applied fine geologic analysis,attributes analysis,analysis of seismic phases,logging phases and sedimentary facies and multi-well-constrained inversion to carry out integral dissection of Es_4 lithologic oil/gas reservoir in west slope of Damingtun sag,which effectively identified underground complex geologic structures and seismic anomalous reflection volume; quantitatively predicted and described the distribution of single layer sandstones in space and their variant law in combination with lithologic interpretation,which achieved good results in exploration and development of oilfield.
