摘要

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。

Abstract: The lateral deformation difference of strike-slip faults on the northern slope of Tazhong uplift and its control on petroleum were studied based on 3D seismic interpretation and attribute statistical analysis. The structural styles of 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 five 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 four 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.
