    澳大利亚海上坎宁盆地油气地质特征及勘探潜力

    PETROLEUM GEOLOGY AND EXPLORATION POTENTIAL OF THE CANNING BASIN OFF AUSTRALIA

    • 摘要: 以石油地质理论为基础,利用区域地质、地震以及钻井资料,对澳大利亚西北陆架海上坎宁盆地的沉积构造演化以及石油地质特征进行了综合分析。研究表明,盆地经历了陆内裂陷期、克拉通边缘坳陷期、被动裂陷期和漂移期4个演化阶段,主要充填了中生界沉积地层。目前,已证实发育2套生储盖组合,已发现油气均集中在三叠系含油气系统中,平面上仅在Bedout坳陷内分布。盆地整体勘探程度较低,油气地质综合分析表明,Bedout坳陷以及Rowley坳陷具有良好的勘探前景。

       

      Abstract: Studies of sedimentary-tectonic evolution and petroleum geological features are carried out in this paper for the offshore Canning Basin on the northwest shelf of Australia, using the data of regional geology, seismics and drillings.It is revealed that the offshore Basin of Canning has experienced four evolutionary stages from intracontinental rifting, through craton margin depression and passive rifting, up to drifting period, and filled with Mesozoic deposits. There occur two sets of source-reservoir-cap assemblages in the Basin.So far, oil and gas have been discovered only in the Triassic petroleum system of the Bedout Depression. However, the whole basin remains rather low in exploration level. Integrated geological analyses suggest that the Bedout and Rowley depressions are prospective for future exploration.
