摘　　要：伊拉克库尔德地区位于扎格罗斯盆地北部褶皱带,油气资源富集,近年来对该区域勘探潜力探索较少。利用前人研究成果及国外数据库最新数据资料,研究库区油气成藏条件和油气成藏因素,探讨其勘探潜力目标。结果表明:伊拉克库区发育的4套含油气系统中侏罗系和白垩系为主力含油气系统;油气主要分布于基尔库克低褶皱带;油气富集的主控因素是优质区域盖层、有效烃源岩的展布和后期构造运动改造;最具勘探潜力的成藏组合是北部低褶皱带三叠、侏罗系低缓背斜圈闭和断层下盘的成藏组合。The Kurdish Region of Iraq is located in the northern folded zone of the Zagros Basin,where oil and gas resources are abundant.In recent years,there has been little study of the exploration potential in this region.The article utilizes previous research results and the latest data from foreign databases to study the conditions and factors of oil and gas accumulation in this area,and studies its exploration potential targets.The research results indicate that among the four sets of oil and gas systems developed in the Iraq reservoir area,the Jurassic and Cretaceous one is the main oil and gas systems.Oil and gas are mainly distributed in the Kirkuk low fold belt.The main controlling factors of oil and gas enrichment are high-quality regional cap rocks,the distribution of effective Source rock and the later tectonic movement.The most promising reservoir formation combination for exploration is the Triassic in the northern low fold zone,the Jurassic low gentle anticline trap,and the re-servoir formation combination in the footwall of the fault.
