摘要
中东地区发育了许多世界级大型油气田,其储层主要为碳酸盐岩。这些碳酸盐岩的地质层位主要是:上二叠统胡夫组;上侏罗统阿拉伯组;白垩系马什里夫组、萨尔瓦克组、舒艾拜组;第三系阿斯马里石灰岩、基尔库克群。该区大油气田的形成有着众多优越条件的有利配置,基本要素可归纳为六个方面:生储盖配置十分合理;有台地内继承性发育的生油盆地;含油气层的年代较新;石油生成的时间较晚,且石油进入构造圈闭的时间也较晚;背斜构造规模巨大;有十分理想的区域性盖层。
Many giant-scaled oil and gas fields developed in Middle East,in which most of reservoirs are comprized of carbonate rocks.These Carbonate rocks mostly distribute in Upper Per- mian Khuff Fm.,Upper Jurrasic Arab Fm.,Cretaceous Mash- irif,Sarvak and Shuaiba Fms,and Tertiary Asmari Limestone and Kirkuk Group.These fields formed under a quite many good conditions,which can be concluded by the following es- sential elements:quite fitted source-reservoir-cap assembla- ges;inherited hydrocarbon-generating basins in platforms; young oil and/or gas reservoirs;hydrocarbon generated late and emplaced late into structural traps;huge-scaled anti- clines;and quite reasonable regional caps.
