波拿巴盆地是澳大利亚重要的产油气盆地,也是世界上著名的富气盆地之一。盆地经历了古生代和中生代多期裂谷作用和新生代挤压作用,充填了15 km厚的显生宙沉积。垂向上,油气主要储集于侏罗系Montara组和Plover组;平面上,石油主要分布在武尔坎次盆和西北构造区,凝析油主要分布在萨胡尔台地和西北构造区,天然气主要分布在卡尔德尔地堑和萨胡尔台地。油气地质综合研究表明,该盆地仍具有较好的勘探前景,勘探程度中等的卡尔德尔地堑、莫利塔地堑和皮特尔次盆西北部勘探潜力较大。

Bonaparte Basin is an important oil and gas producing basin in Australia and one of the world-class gas-rich basins.It experienced several stages of rifting and the remobilization of the faults.The basin was filled with about 15 km thick sediments.Some sets of source rocks and reservoir were developed in Bonaparte Basin.Hydrocarbon is mainly reserved in the Permian,Triassic and Jurassic.Regionally,oil is mostly distributed in the Vulcan Sub-basin and the northwest of the basin.Condensate is distributed in the Sahul Platform and the northwest of the basin.Gas is mainly distributed in Calder Graben and Sahul Platform.Integrated petroleum geological analyses indicate that the basin has considerable exploration potential.The moderately explored Calder Graben,Malita Graben and the northwest of Petrel Sub-basin comprise the areas with the best exploration potential.
