| 摘 要： | 巴布亚盆地的构造演化主要受控于陆内克拉通裂谷、冈瓦纳裂解、珊瑚海裂开、美拉尼西亚岛弧碰撞4个构造事件,它们共同影响并控制了该带的构造沉积演化和油气成藏。盆地内主要发育3个褶皱带,分别为伊利安褶皱带、巴布亚褶皱带和奥雷褶皱带,它们主要发育压缩构造样式,由于受到挤压应力的强弱变化,褶皱带构造挤压强度北强南弱,构造类型丰富多样。

| Abstract: | The Papuan Basin is a petroliferous basin with complex structure but low exploration degree. The structural evolution of this basin is mainly controlled by four tectonic events, i.e., intracontinental craton rift, Gondwana breakup, the Coral Sea split and Melanesia arc collision, which jointly influence and control the tectonic-sedimentary evolution and hydrocarbon accumulation. Three main fold belts are developed in the basin, i.e., the Irian fold belt, Papuan fold belt and Aure fold belt, with a major compression tectonic style. Due to the variations of extrusion stress, the tectonic compression strength of the fold belts shows a southward weakening trend, with complex structural styles. It is very important for the petroleum exploration in the Papuan Basin to further analyze the relationship between fold belt types and hydrocarbon-generation evolution. |
