摘　　要：基于三维地震资料精细解释,结合相干属性统计分析,对塔中北坡走滑断裂的横向变形差异及其油气地质意义进行研究。研究结果表明,塔中北坡左旋走滑断裂构造样式主要以发育单一陡倾断层、正花和负花上下叠置的"复合花状"构造和雁列式正断层为主。根据断裂构造样式,将顺托1号走滑断裂沿走向分为5段,自东向西上、下断层逐渐相互贯通;顺南2走滑断裂沿走向分为4段。根据变形强度,将顺托1号走滑断裂分为5个强变形段和4个弱变形段;顺南2走滑断裂分为2个强变形段和2个弱变形段。走滑断裂构造样式、变形强度的横向差异对储层发育、油气运移有重要影响。The lateral deformation difference ol strike-slip faults on the northern slope ol Tazhong uplift and its control on petroleum were studied based on 3D seismic interpretation and attribute statistical analysis. The struc-tural styles ol the strike-slip faults included single steep strike-slip faults,overlaid positive and negative flowers, and en echelon normal faults. The Shuntuo No. 1 strike-slip fault was divided into live parts along its strike, changing from cover-decollement to basement involvement patterns from east to west. The Shunnan-2 strike-slip fault was divided into four parts along its strike. According to deformation strength,the Shuntuo No. 1 strike-slip fault was divided into five strong parts and lour weak parts,while the Shunnan-2 strike-slip fault was divided into two strong parts and two weak parts. The deformation difference of strike-slip faults played an important role in reservoir development and hydrocarbon accumulation.
