Comparative studies of petroleum geological conditions in key basins offshore Argentina and exploration recommendations

摘要:
阿根廷油气资源丰富，并且油气财税条款较为优越，与国外大型油公司和中国油公司均有油气勘探资产合作，适合我国海外油气勘探投资。阿根廷海域13个盆地以转换断层为界，可划分为南部盆地群和北部盆地群，南部、北部盆地群在早期裂谷盆地的基础上分别逐渐演化为前陆盆地和被动大陆边缘盆地。南北盆地群由于盆地类型不同、构造演化不同，导致其构造特征、地层充填特征和油气成藏条件等方面具有一定的差异性特征。通过对阿根廷海域南部前陆盆地群和北部被动大陆边缘盆地群构造演化、地层充填、烃源岩条件、储层条件和圈闭条件对比研究，对阿根廷海域盆地石油地质特征有了进一步的认识，指出南部的前陆盆地成藏条件要优于北部被动大陆边缘盆地。分析表明，南部盆地群中的马尔维纳斯前陆盆地为剩余有利勘探区，该盆地勘探程度低，已证实具有油气发现，推测盆地中南部为有利构造带，或许将成为阿根廷未来的勘探热点。
Abstract:Argentina is rich in oil and gas resources and superior in fiscal and tax terms. Large foreign oil companies and Chinese oil companies cooperate with Argentina in oil and gas exploration, which is suitable for China's overseas oil and gas exploration investment. The 13 basins in the Argentine offshore can be divided into the southern basin group and the northern basin group by transformation faults. The southern basins gradually evolved into foreland basin on the basis of the early rift basin, while the northern basins gradually evolved into passive continental margin basin on the basis of the early rift basin. Due to different basin types and tectonic evolution, the northern and southern basins have different characteristics in structural characteristics, sedimentary characteristics and hydrocarbon accumulation conditions. We have known more and more about the petroleum geological conditions of the Argentine offshore basins through the comparison research on tectonic evolution, hydrocarbon, reservoir, seal, trap and hydrocarbon distribution features of the northern and southern basins. The study shows that the petroleum geological conditions in southern foreland basins are better than the northern passive continental margin basins. Further analysis indicates that the Malvinas Basin has relatively good exploration potential because of its lower exploration degree, proven petroleum system. It is assumed that the central and southern part of Malvinas Basin with favorable structural belts, may be the petroleum exploration focus in the future.
