摘要: 波斯湾盆地深部古隆起控制巨型低幅背斜的发育,进而控制世界级大型油气田的形成。亟须精细刻画波斯湾盆地深部古隆起和断裂的分布特征、深入分析其对油气分布的控制作用。基于高精度EGM自由空气重力数据小波分析,在中阿拉伯次盆、鲁卜哈里次盆和扎格罗斯次盆精细识别出36个古隆起。根据古隆起形成演化过程,将其划分为3期:前寒武纪古隆起、晚泥盆—早石炭世古隆起、中—上新世古隆起。第1 期和第2 期古隆起控制前寒武系—泥盆系背斜构造圈闭、泥盆系削截不整合—岩性圈闭以及二叠系—白垩系背斜构造圈闭的发育。第3 期古隆起控制中-上新世披覆背斜圈闭的发育。结合波斯湾盆地成藏条件配置关系,预测出16个古生界油气藏有利区、26个侏罗系油气藏有利区和16个白垩系油气藏有利区,为波斯湾及类似盆地的深层油气勘探提供借鉴。

Abstract: The deep palaeohigh in the Persian Gulf Basin controls the development of the giant low-amplitude anticline, which in turn controls the formation of the world-class large oil and gas fields. It is urgent to delineate the distribution characteristics of deep paleohigh and fault in the Persian Gulf Basin and analyze their control on oil and gas distribution. Based on the wavelet analysis of high precision EGM free air gravity data, 36 palaeohighs are identified in Centrel Arabian, Rub’al-Khali and Zagros subbasins. Combining with the formation and evolution of palaeohighs, these palaeohighs are divided into three groups: Precambrian, Late Devonian to Early Carboniferous Epoch, and Mio-Pilocene. The first and second groups of palaeohighs control the development of Precambrian to Devonian anticlinal traps, Devonian unconformity lithologic traps, Periman-Cretaceous anticlinal traps. The third group of palaeohighs control the development of Mio-Pilocene drape anticlinal traps. Based on the reservoir formation conditions in the Persian Gulf Basin, 16 Paleozoic, 26 Jurassic and 16 Cretaceous favorable areas are predicted. This study can provide some reference for deep oil and gas exploration in the Persian Gulf and similar basins.
