摘要： 侏罗系是柴达木盆地的重要含油岩系,近年勘探连连有新发现。从柴达木盆地侏罗系油藏成因条件分析入手,指出,盆地中的侏罗系油藏为原生油藏,而第三系油藏则是原油通过断裂再 次运移而形成的次生油藏 ,应 当开展区域勘探和综合研究工作,在确定生油凹陷的基础上,实施定凹探边的方针。据初步分析,一里坪坳陷中的一里坪凹陷,侏罗系生油条件较好。因此,除冷湖—南八仙已知含油带外,鄂博梁背斜带可能是含油气富集带,伊克雅乌汝背斜带也应注意。

Abstract: Jurassic strata are an important petroleum bearing sequences in Qaidam basin. In recent years,exploration activities have been made with new discoveries. Based on the analysis of origin and conditions of Jurassic reservoir in Qaidam basin, it is pointed out that it is a primary reservoir,while Teriary reservoir is a secondary one formed from crude oil remigration through the fault, and it is necessary to conduct regional exploration and comprehensive studies in order to determine the source sag. Based on this, the guiding principle of determining sags for reservoir delineation should be performed. According to the preliminary analysis, there existed good conditions for hydrocarbon generation in Yiliping sag of Yiliping depression. Hence, beside the known crude-bearing zones,Eboliang anticline may be another petroleum accumulation zone, but Yikeyawuru anticlinal belt should be paid attention to.

Key words: Qaidam basin, Jurassic, primary reservoir, continental deposit, marine deposit, remigration
