中文摘要 | 東亞中、新生代沉積盆地的演化,一般歷經斷陷、坳陷、反轉三個階段。反轉構造 為東亞最重要的儲油氣構造,中國最大的油田-大慶油田,東海西湖凹陷平湖油氣田, 東南亞最大的油田-印尼中蘇門答臘盆地Minas油田,均為構造反轉所形成的擠壓背斜 構造。臺灣已知的儲油氣構造,百分之九十以上與反轉構造作用有關。 中蘇門答臘盆地為反轉盆地的典型範例,該盆地的油田均與反轉構造作用有關。在 發生構造反轉之前,該盆地在斷陷階段沉積了巨厚的湖泊相、河流相含煤地層,在凹陷 階段沉積了良好的儲集岩層及蓋層。構造反轉形成的背斜直接蓋在生油凹陷之上及其鄰 近,而長期活動的斷裂,又對油氣運移提供通道,因此形成油氣生成、運移、聚集的有 利空間配置關係。 |
英文摘要 | The Mesozoic-Cenozoic basins in East Asia generally have undergone three evolutionary stages: rifting, depression and inversion. Inversion structure is the most important trap for hydrocarbon accumulation in East Asia. The Daqing Field in the Songliao Basin, the largest oilfield in China, the Pinghu Field in the Xihu Depression, East China Sea Basin, and the Minas Field in the Central Sumatra Basin, Indonesian, the largest oilfield in Southeast Asia, are all characterized by inversion structure. The Central Sumatra Basin is an ideal model for petroleum exploration in inverted basin. Most of the oil accumulations in the basin are controlled by inversion tectonics. The largest oil accumulations in the basin result from combination of Paleogene graben with thick oil-prone lacustrine shales overlain by thick marine clastic reservoirs of Miocene age, high basin heat flows, and inversion tectonics that formed traps above or near the kitchen center of graben and prior to the main phase of maturation and migration. |
