Fault attributes generally display a consistent power–law-scaling *** on new 3 D seismic data,however,we found some exceptional fault attribute relationships of lengths(L)–throw(T)(vertical component of displacement),overlap zone length(Lo)–width(Wo)from a strike-slip fault system of the Ordovician carbonates in the Tarim *** L–T relationship shows two linear segments with breakup at^40 km in fault *** presents an exceptional throw increase in the second stage,which is attributed to a localization of vertical displacement and deformation in overlapping zones other than the different fault scales in a mature fault *** Lo–Wo relationship in the overlapping zones shows multiply stepped-shape patterns,suggesting multiple fault differential growth and periodic increase in fault ***,we propose a new alternative growth model of fault attributes in strike-slip fault zones,in which the overlapping zones accumulated localized displacement and deformation in the intracratonic strike-slip fault zone.

在塔里木盆地开辟了超深层走滑断控油气藏勘探开发领域,但断控油气藏极为复杂,难以效益开发,亟需加强油气藏基础地质研究。走滑断控油气藏具有非均质性强、储集层与流体分布复杂、油气产量变化大及采收率低的共性,不同地区走滑断控油气藏的断裂、储集层、成藏与流体存在较大的差异,面临一系列勘探开发难题。建立了差异成因的走滑断裂破碎带及其控储模型,揭示了沿走滑断裂带“相-断-溶”三元复合控储、连片差异规模发育的成储机制;构建了“源-断-储-盖”四元耦合成藏、“小藏大田”的走滑断控油藏模型,揭示了超深层走滑断控油藏的形成与保存机理。突破了克拉通盆地弱走滑断裂难以形成走滑断控大规模储集层与大油气田的理论认识局限,明确了克拉通盆地走滑断裂系统大规模发育的成因机制、走滑断裂破碎带差异成储成藏机理与油气富集规律。
