The Shunbei No. 4 strike-slip fault zone which is located in the Shuntuoguole low uplift of the Tarim basin and extends northward to the Shaya uplift is characterized by deep burial,horizontal segmentation,vertical stratification,multi-stage activities,and complex structure. Through the interpretation of high-quality 3D seismic data from the Shunbei No. 4 strike-slip fault zone,the stratification,segmentation,staging,activity and favorable area evaluation of the fault zone were carried out. The results show that the Shunbei No. 4 strikeslip fault zone has a 4-layer structure in the Paleozoic,roughly bounded by the top of the Middle Ordovician,above which echelon faults are found and below which high-steep strike-slip faults are developed. The strike-slip fault zone is visibly segmented into the northern segment,the middle segment,and the southern segment according to the strike,showing an overall characteristic of compressed in south and extended in north. In the Paleozoic,the strike-slip fault zone successively experienced four periods of activity,namely,EpisodeⅠof the middle Caledonian,Episode Ⅲ of the middle Caledonian,late Caledonian,and Hercynian. By combining the main controlling factors（e.g.source-reservoir connectivity,reservoir size,and late adjustment） for hydrocarbon enrichment and accumulation in the Shunbei area,the favorable areas in the Shunbei No. 4 strike-slip fault zone were evaluated. Multiple favorable areas have been identified and then verified by actual drilling.

超深层碳酸盐岩储层非均质性强,其内部结构受地震资料精度限制,规模储层预测和分布认识存在难度.选取顺北中部北东向断裂体系的顺北4号断裂带为研究对象,开展断裂构造破碎成储物理模拟实验、井震精细标定、模型正演、储集体表征、储集体地质模型研究,提出断裂面附近发育多个由空腔、裂缝带组成的多组缝洞集合体,建立了走滑断裂栅状储集体结构模式,阐明走滑断裂栅状储集体的成因机制与主控因素,构建了断裂带规模储集体"一体多栅"结构模型,形成了断控储集体空间定位与"一井多控、一井一靶、一井多靶"分类井轨迹设计方案.成果应用指导了顺北4号、顺北8号断裂带钻井轨迹设计,实现了断控缝洞型复杂油气藏的"少井高产",新增一个百万吨产能新阵地,对我国其他盆地超深层断控型油气藏的勘探具有一定指导与借鉴意义.
