无井地震储层预测及烃类检测——以北黄海中部坳陷A构造为例
|
摘要
北黄海盆地是中国东部勘探及研究程度较低的含油气盆地之一,从原始地震资料分析入手,利用研究区波阻抗、道积分、瞬时振幅、瞬时频率等多种地震资料特殊处理方法及AVO油气检测技术,并结合沉积相和区域地质资料,对北黄海中部坳陷A构造的储盖层分布、含油气性等油气地质条件进行分析预测,认为研究区A构造中新生带地层纵向上主要有两套有利的储盖组合,且构造中部和翼部含油气性较好。
The North Yellow Sea Basin is one of petroliferous basins where the exploration and study degree is low in east China.Beginning with analysis of original data in the study area,using special treatment methods of seismic data such as the impedance,instantaneous amplitude,instantaneous frequency,etc.,as well as other AVO oil and gas examination technology,combined with regional sediment and geological data,this paper generally analyzes the reservoir,seal distribution,and oil and gas geological conditions of Structure A in the central depression of the North Yellow Sea Basin.It is concluded that there are two sets of advantageous reservoir and seal compounding in the area,and the oil and gas condition at the center and limb of the Structure is better.These results have an important guiding sense for study of the petroleum trap distribution in the research area.
