渤海湾SZ36-1S地区高精度层序约束下储层预测与岩性油藏勘探潜力分析
|
摘要
以钻井、测井、高分辨率三维地震资料为基础,以高分辨率层序地层学理论为指导,对SZ36-1S地区东二下亚段不同级别的基准面旋回进行划分,从中识别出4个中期旋回,13个短期旋回。以短期旋回为基本地层单元,在连井层序地层对比的基础上,建立了SZ36-1S地区东二下亚段高分辨率等时地层对比格架,并结合地震属性分析与波阻抗反演资料,对砂体的分布规律与主控因素进行了分析和预测,为今后的精细油气勘探指明了方向。
Based on seismic data,well logging and drilling data,under the guidance of high resolution sequence strati-graphy,the base level cycles in the SZ36-1S area are divided into four mid-term cycles and 13 short-term cycles.Making the short-term cycle as the basic time stratigraphic unit,the high resolution sequence stratigraphic framework in SZ36-1S area is established based on well tie sequence stratigraphy contrast.Combined the seismic attribute analysis and wave impedance inversion data,the distribution of sand bodies is predicted and the main controlling factors for sand bodies are analyzed,which designates the direction for the further oil and gas exploration.
