【摘要】：波拿巴盆地是澳大利亚主要含油气盆地之一,也是我国石油公司海外油气勘探涉足的重点区。通过深入分析盆地油气地质特征,认为该盆地主要发育中生界含油气系统,油气分布呈现东部富气、西部油气并存的特点。通过分析盆地东、西部在构造样式、烃源岩成熟度、圈闭形成背景和保存条件等方面的差异,将该盆地中生界成藏组合在平面上划分为乌尔坎和马里塔2个评价单元,并以勘探趋势法和分段式油藏规模序列法为手段确定评价参数,采用蒙特卡洛法预测该盆地的石油、凝析油和天然气待发现可采资源量分别为934 MMb(1.48×10~8 m~3)、1 909 MMb(3.04×10~8 m~3)、34 387 Bcf(9 737.3×10~8 m~3)。综合分析认为,该盆地具有很高的勘探潜力,马里塔坳陷是下一步寻找大中型气田的有利勘探区。
[Abstract]:The Bonaparte Basin is one of the major petroliferous basins in Australia, and is also the key area for China's oil and gas companies to explore overseas oil and gas. Based on an in-depth analysis of the basin's oil and gas geological characteristics, it is considered that the basin mainly develops Mesozoic oil and gas bearing systems. The distribution of oil and gas presents the characteristics of rich gas in the east and the coexistence of oil and gas in the west. By analyzing the differences between the east and west of the basin in structural style, maturity of source rocks, trap formation background and preservation conditions, etc. The Mesozoic reservoir formation assemblage in this basin is divided into two evaluation units, Ulcan and Marita, and the evaluation parameters are determined by exploration trend method and segmental reservoir size sequence method. Monte Carlo method is used to predict the oil in the basin. The recoverable resources of condensate oil and natural gas to be discovered are 934 MMb(1.48 脳 10 8 m ~ (3) ~ 1 909 MMb(3.04 脳 10 ~ (8) m ~ (3) Bcf(9 ~ (34) 387 Bcf(9 73 ~ (7 3) 脳 10 ~ (8) m ~ (3) ~ (-1) respectively. The comprehensive analysis shows that the basin has a high exploration potential, and the Marita depression is a favorable exploration area for finding large and medium gas fields in the next step.
