| 摘 要： | 四川盆地九龙山地区侏罗系珍珠冲组砾岩段气藏为构造—岩性气藏,受构造、储层、裂缝等多因素控制,并受地震资料品质和解释思路的影响,应用地震剖面、常规相干体切片不能对微断裂进行精细刻画。文中在构造导向滤波的基础上联合运用谱分解、新一代相干体切片和体曲率技术,精细刻画了微断裂的空间展布规律,说明多属性微断裂识别技术是可靠的断裂识别手段,其中体曲率属性对断层及微断裂的刻画更为清晰。野外地质考察及最新钻、测井资料的验证结果表明,珍珠冲组砾岩段微断裂十分发育,以北东、北西向为主。

| Abstract: | In Jiulongshan area of Sichuan Basin,the gas reservoirs of conglomerate section in Jurassic Zhenzhuchong formation are structural-lithologic,controlled by structure,reservoir,fracture,and other factors.Due to seismic data quality,micro-fault cannot be subtly depicted by traditional ways on seismic sections and conventional coherence slices.With structure-oriented filter,we use spectrum decomposition,new generation coherence slices and volumetric curvature technology to subtly depict spatial distributions of... |
