摘　　要：在系统回顾走滑断裂研究历史、形成机制和基本构造特征的基础上,重点讨论了我国大型克拉通叠合盆地走滑构造与油气聚集方面的最新研究进展.概括起来包括:(1)走滑断裂应力和生长机制决定了走滑断裂体系和构造样式具有“平面分区、走向分段、侧向分带、垂向分层、层内分异”特征;(2)板内走滑断裂与油气富集关系表明走滑断裂带具有“控源、控输、控储、控圈、控藏和控富”作用;(3)这种断控孔缝洞型储集体的表征可以从露头测量→测井资料刻画→三维地震雕刻3个方面进行,其核心是裂缝密度的分布与预测;(4)板内走滑断裂带断控油气藏通源性、充注过程和年代学研究为克拉通盆地深层-超深油气勘探提供了新的工具.另外,对本专辑发表的论文进行了评述.以期对推动我国克拉通盆地深层-超深层油气勘探起到抛砖引玉之功效.On the basis of review of strike-slip fault research history,formation mechanism and principal structural characteristics,the relationship between strike-slip fault in intraplate cratonic basins and hydrocarbon accumulation in China are emphatically discussed in this paper,which can be outlined as follows.(1)Strike-slip fault stress,growth mechanism and structural style determine the strike-slip fault belt having five features of“different systems in planar,segmentation in strike,zoning in lateral,layering in vertical,and differentiation within layers”.(2)The relationship between strike-slip faults within intraplate and hydrocarbon accumulation indicates that the strike-slip fault plays six roles of“controlling source,transmission,reservoir enhancement,trap-forming,reservoiring,and hydrocarbon enrichment”.(3)The delineation of this strike-slip-controlled reservoir bodies can be conducted from outcrop measurement to log data depiction to 3D seismic data characterization in steps,and the key is fracture distribution acquirement and fracture density prediction.And(4)the studies of hydrocarbon sourcing,charging and dating for the exploration of strike-slip-controlled reservoirs in intraplate provides a strong tool in the deep and ultra-deep cratonic basins in china.In addition,the comments of published papers in this special issue have been made.The expectation of this issue is serving as a modest spur to promote hydrocarbon exploration to come forward with the valuable contributions in China in future.
