摘　　要：伊拉克位于阿拉伯板块东北部,跨越5个构造带,油气成藏条件比较复杂。在综合分析伊拉克构造、沉积、地层岩性和沉积相以及油气分布特征的基础之上,把侏罗系划分为Najmah、Sargelu-Naokelekan、Mus和Butmah等4个成藏组合,并对各成藏组合的储集层、盖层、烃源岩等地质要素进行评价,分析各成藏组合特征。在以上研究的基础之上,划分出3个级别的侏罗系有利勘探区,并分别进行评价,认为美索不达米亚盆地的东南部最为有利,其次为伊拉克东北部的褶皱带,但同时都具有较大的勘探开发成本和风险。Iraq is Located in the northeastern Arabian plate crossing five tectonic belts. The reservoirforming conditions are very complex. After comprehensive analysis of its structure, sedimentation, strata lithology and litholodical facies as well as hydrocarbon distribution, this paper divided the Jurassic into such four plays as Najmah play, SargeluNaokelekan play, Mus play and Butmah play andanalyzed the char acteristics of them, according to the evaluations of the reservoirs, cap rocks and source rocks. Furthermore, this paper presents three favor able exploration areas in different levels. It is recognized that the southeastern Mesopotamia basin is the most potential area for Jurassic pe troleum exploration, followed by the folded zone in the northeastern Iraq. But the cost and risk for their exploration and development are al so very high.
