| 摘 要： | 本文根据三水盆地下第三系心组有机地化资料的分析,确定其生油门限深度为400米。进一步讨论了影响我国东部第三系含油气盆地成油门限值的几种地质因素。提出这些年青的盆地只要具有高地温梯度、高沉降速度、埋深大、剥蚀少就能在较短时间中形成油气。 |
| 关 键 词： | 三水盆地 生油门限 沉降速度 |
THE GEOLOGICAL FACTORS AFFECTING THE THRESHOLD DEPTH OF OIL GENERATION |

| Abstract: | Based on organo-geochemical analysis of the Buxin Formation of Eocene in Sanshui basin, the threshold depth of oil generation is determined as 400m. This paper discusses some factors affecting oil-generation threshold depth of the Tertiary basins in East China. It indicates that these young basins can generate oil and gas in shorter time, if there are high geothermal gradient, high rate of subsidence, great depth, and less erosion. |
| Keywords: | Sanshui basin threshold of oil-generation rate of subsidence |
