摘要: 塔里木盆地阿瓦提断陷长期以来未能取得与生烃坳陷相对应的油气勘探成果,勘探部署方向正处于探索之中。结合近期勘探取得的资料和新的研究进展,综合分析了阿瓦提北—顺托果勒北地区的石油地质条件,从含油气系统的角度,指出了阿瓦提寒武—奥陶系含油气系统(!)的最有利目标为研究区东部的中下奥陶统碳酸盐岩缝洞型储集体,其次为顺大断裂带分布并在燕山期及以前定型的圈闭;库车三叠—侏罗系含油气系统(!)的有利目标为研究区东部白垩系、古近系岩性圈闭和喜山早期不整合面上下的各类圈闭;阿瓦提三叠系含油气系统(?)有利方向为三叠系近烃源岩三角洲砂体、湖相浊积岩体。Abstract: In the past years,few achievements in accordance with the scale of hydrocarbon generation depression have been obtained in petroleum explorations in Avat area of the Tarim Basin and the favorable exploration targets still remain exploring.Based on new exploration data and research progresses,it is discussed in this paper the petroleum geologic conditions in the northern Avat and the northern Shuntuoguole areas.Three petroleum systems have been identified according to petroleum system theory.As to the Cambrian-Ordovician petroleum system(!) in Avat area,the most favorable exploration target is the middle-lower Ordovician karst-vuggy carbonate reservoir in the east of the study area.The traps formed in or before Yanshan period along big faults are less favorable.For the Triassic-Jurassic petroleum system(!) in Kuche area,the most favorable exploration targets include Paleogene-Cretaceous lithologic traps and various traps of unconformity fluctuation of early Himalayan epoch in the east of the area.Delta sandbody and lacustrine turbidite mass are favorable targets in the Triassic petroleum system(?) in Avat area.
