摘要
川东北元坝地区须家河组气藏受岩性、储层、裂缝等多因素控制,其中构造断层及其伴生裂缝的发育和展布特征是须家河组天然气聚集成藏、高产的主控因素之一。在构造导向滤波的基础上联合运用相干、体曲率技术,精细刻画了断层的空间展布,并在此基础上总结了断层分布特征与油气成藏的关系。
In Yuanba area,northeastern Sichuan Basin,the gas reservoir of Xujiahe Formation is controlled by many factors,containing lithology,reservoir and fracture.Moreover,the main controlling factors to form gas accumulation and to sustain high yield are development and distribution of structural faults and their associated fractures.In this paper,on the basis of structural steerable filter,combined with coherence and body-curvature technologies,the spatial distribution of faults are studied,and the relationship between their distribution and forming reservoir is also summed up.
