英台地区构造—岩性复合油气藏解释技术的应用与效果
|
摘要
英台地区是中国东部近几年勘探成效最显著的地区之一。该区地层物性条件好、产能高 ,油气成藏受断层断距、断层延伸长度、砂体厚度影响明显 ,油气富集区主要位于小幅度构造圈闭内 ,油气藏主要以构造—岩性复合油气藏为主。本文根据该区的石油地质特点 ,充分利用三维地震资料 ,应用三维可视化解释技术、相干体和地层倾角检测技术、多属性模型约束反演储层预测技术对主要目的层进行了解释和圈闭评价。经钻井验证 ,所应用技术实用、有效 ,具有推广价值
Yingtai area is one of the areas in the east of China where the exploration has prominent effect.The area has good stratigraphic physic condition,high production capacity.The influence of throw,extension of fault and thickness of sand body on reservoir are obvious.Oil gas accumulation mainly are concentrated into structural trap with low relief.The reservoirs mainly are structural lithologic composite reservoirs.According to the petroleum geologic characters of the region and fully using 3 D seismic data,the paper uses 3 D visualization interpretation technique,coherent body and stratigraphic dip detection technique,reservoir prediction technique and multi contribution model constrained inversion for interpretation of main targets and appreciation of traps.The applied techniques are practical and effective after drilling examination,having generalized value.
