走滑断裂及其伴生的裂缝,是准噶尔盆地西北缘玛南斜坡区三叠系百口泉组储层的重要控制因素,走滑断裂及裂缝的识别与预测对于该地区高产目标的识别有着重要意义。然而走滑断裂垂向断距小甚至无断距,断层识别和组合比较困难；与断裂伴生的裂缝发育与地震资料分辨率不在同一尺度,以地震资料识别和预测裂缝发育带的可靠性受到较多质疑。针对这些问题,采取地震地质综合识别技术,①充分运用构造导向滤波、多尺度边缘检测、方向加权相干、体曲率分析等手段,尽量精确可靠地提取构造变形引起的地震响应特征；②利用走滑断裂的 Sylvester剪切模式与断层裂缝相关等地质理论进行地质约束,对地震识别和预测结果进行合理解释和推断,从而较好地解决了这一地区走滑断裂和裂缝发育带的识别与预测问题。

Strike-slip faults and associated fractures are an important controlling factor of Baikouquan reservoir of Junggar basin Manan slope zone.The recognition and prediction of strike-slip faults and fractures are significant for recognition high productive targets.However,it is difficult to distinguish and combined for the little vertical fault throw of strike-slip faults. The reliability of seismic data to identify and predict fracture zones subject to more questioning for that fractures and seismic da-ta resolution is not in the same scale.Adopting comprehensive geological seismic recognition technology can solve this problem in two ways.On the one hand,some methods such as structure oriented filtering,multiscale edge detection,direction weighted coherence and volumetric curvature are effective for fault identification for structure deformation characteristics.On the other hand,faults and fractures can be reasonable interpreted and inferred on the base of Sylvester shear mode and geological theory such as the association of strike-slip faults and fractures related,which is a better solution to the region to identify and predict strike-slip fault and fracture zone.
