澳大利亚奥特韦盆地油气地质特征与资源潜力

Petroleum geologic characteristics and resource potentials in Otway Basin of Australia

从区域构造背景和地层沉积特征描述了澳大利亚奥特韦盆地的基础地质特征;从烃源岩、储集层和圈闭三个方面论述了盆地的油气成藏条件;从平面和层系上总结了盆地的油气分布特征。截止到2008年底,该盆地累计生产天然气124.5×108m3,经济和次经济意义的证实储量为石油2×106t,天然气350×108m3。对盆地的资源潜力进行评价,并对有利的远景区进行预测。

Basic geological characteristics in Otway Basin of Australia have been described from regional tectonic settings and depositional characteristics.Oil-gas accumulation conditions of the basin are discussed based on analysis of source rocks,reservoirs and traps.Oil-gas distribution features are summarized from flats and layer series.As of the end of 2008,cumulative gas production in the basin was 124.5×10^8 m^3,the economic and sub-economic proven oil reserves is 2×10^6 t,and the natural gas reserves is 350×10^8 m^3.Finally,the resource potential of the basin is evaluated and the favorable prospect area is predicted.
