摘要
南方海相地质条件,既不同于国外稳定地台区海相盆地的特点,又不同于国内陆相盆地的特点,因此不能简单地套用已有的成功模式。对勘探选区提出了几点看法:(1)圈出生油最有利地区;(2)在近油源的古高地找油气;(3)保存条件是关键;(4)以找气为主;(5)重视晚期成藏的理论。中国南方缺少油气长距离运移的条件,只有在近油源的地方才容易找到原生的和经过次生运移的油气藏。
The petroleum and natural gas geological condition of marine sequences in southern China is different both from that of marine basins in external stable platforms and that of domestic continental basins. So the present successful models couldn't be mechanically taken to the exploration of southern Chi- na. It lacks the condition for oil and gas migrating for long distance. Only near the source rocks could we be most possible to find original/secondary oil & gas reserviors. Some opinions: (1) drawing out the most favourable regions of source rocks, (2) looking for oil & gas pools on ancient uplifts near source rocks, (3) the preservation condition is the key factor, (4) taking natural gas as the dominent object of explo- ration, (5)attaching importance to the theory of Late Accumulation.
