Abstract

The principal basins on the Mozambique continental margin are the Mozambique and Rovuma, on the passive continental margin with complex tectonic history, following after the East African Rift System in the Triassic. Although the first gas fields in the coastal zone of the Indian Ocean in southeast Mozambique are appeared yet in the 1960s, only in 2010, did Mozambique achieve a new status as a major world hydrocarbon player—with the discovery of a number of large gas fields in the northeast of the country, in deep-water regions of the Indian Ocean, and in the Rovuma Basin. More than 20 recently discovered gas fields are located in deep-water regions and on the continental slope of the Indian Ocean at depths of 468–2610 m. It is noteworthy that the pays of the same age, the deeper they are buried beneath the water column, the greater their volume of hydrocarbon reserves. A similar trend may help in the case of targeted oil and gas exploration. The prospects of liquid hydrocarbon discoveries are possible in the Madagascar channel behind the Davie Ridge and in deep-water parts on the slopes of the Mozambique continental margin.

莫桑比克含油气大陆边缘的地质结构和前景
摘要 莫桑比克大陆边缘的主要盆地是莫桑比克盆地和罗武马盆地,位于被动大陆边缘,具有复杂的构造历史,是三叠纪东非裂谷系统之后的产物。虽然莫桑比克东南部印度洋沿岸地区的第一批气田出现在 20 世纪 60 年代,但直到 2010 年,莫桑比克才取得了世界油气大国的新地位--在该国东北部、印度洋深水区域和罗武马盆地发现了许多大型气田。最近发现的 20 多个气田位于印度洋 468-2610 米深的深水区域和大陆坡上。类似的趋势可能有助于有针对性地勘探石油和天然气。戴维海脊后面的马达加斯加海峡和莫桑比克大陆边缘斜坡的深水区有可能发现液态碳氢化合物。
