中国南方海相盆地经历了多旋回运动的叠加改造,导致各地区油气保存状况存在较大差异。因此,须探索此类盆地独特的油气成藏规律。研究过程中,应注重突出重点、以点带面,针对不同地区的特点,总结出各自的成藏模式。目前,南方海相研究应重点放在重点区块构造评价、烃源岩重新确定和保存条件再评价等方面。通过解剖典型油气藏的成藏条件,了解成藏要素的有利匹配,优选出近期的勘探目标。

Superimposed reformation of multi-cyclic tectonic movements experienced by marine basins in Southern China result in quite differences of oil and gas reserving in various areas. Therefore, a special regularity of the generation of oil and gas reservoirs (play) in these basins must be probed. Focal point shall be stressed in the research and each oil and gas play pattern shall be summarized accordingly to the feature of various areas by fanning out from point to area. At present, emphasis shall be put on the assessment of regional block tectonics and on the reassessment of re-determination and reserving conditions of hydrocarbon resource rocks when studying marine facies in Southern China. The latest exploration target can be selected out by dissecting play conditions of typical oil and gas reservoirs and getting to know favorable matching of play elements.
