【摘要】 塔里木盆地玉北地区油藏具有埋藏深、油层薄且分散、相带变化快、油水关系复杂、分割性强、井与井之间可比性较差等特点,应用常规地震储层预测方法很难满足该区块油藏开发的需要。为落实玉北地区玉北1井油田海相碳酸盐岩含油性富集区的评价,指明有利储油层分布规律,通过提取地震数据结构属性,达到预测油气的目的。该属性基于地下岩层层序结构、岩性和含油气等发生纵横向变化引起地震反射波的变化。实际钻井资料验证了该方法有较好的效果。更多还原

【Abstract】 Reservoirs in Yubei,Tarim Basin are characterized by deep buried,thin and disperse beds,fast facies changes,complex oil-water relationship,strong segmentation,and poor comparison between wells.Conventional seismic reservoir prediction methods cannot deal with these kinds of problems.We extract seismic structure attributes for the evaluation of Well Yubei-1 area.These structural attributes present characteristics of seismic reflections caused by underground rock stratigraphy,lithology and hydrocarbon changes,which are helpful for analysis of carbonate reservoir enrichment and distribution.Real drilling data prove the effectiveness of this approach.更多还原
