塔中北坡走滑断裂横向变形差异及其油气地质意义
Lateral deformation difference of strike-slip faults on the northern slope of Tazhong uplift and its control on petroleum geology
摘要
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 struc?tural 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.关键词
