摘要: 系统分析了塔中北斜坡走滑断裂构造特征,研究了走滑断裂的形成演化及其对油气成藏的控制作用。研究表明,自奥陶纪以来,塔中北斜坡中部走滑断裂活动主要有5期。走滑断裂的形成和演化影响着下奥陶统碳酸盐岩岩溶储集层纵向发育深度范围及横向展布形态。多期活动的走滑断裂为油气垂向运移提供了良好的通道。在塔中北斜坡背景下,岩溶储集层发育,长期活动的走滑断裂和逆冲断裂交汇处的局部构造高点是油气运聚成藏的有利指向区。

Abstract: The structural characteristics of strike-slip fault in the northern slope of Tazhong area are analyzed. The controls of strike-slip faults on hydrocarbon reservoir are investigated. Study shows that there were five-period activities of the strike-slip faults in the middle of it since the Ordovician. The formation and evolution of the strike-slip faults control the vertical depth and lateral distribution pattern of the carbonate reservoir of the Lower Ordovician. The multistage active strike-slip faults serve as good channels for hydrocarbon vertical migration. In this setting, the development of carbonate reservoir is subjected to damage of some small faults, so the local structural highs at intersections of long-term active strike-slip faults and thrust faults will be the favorable areas of hydrocarbon migration and accumulation.

Key words: Tarim basin, Tazhong area, strike-slip fault, carbonate rock, reservoir modification, oil-gas migration channel
