摘要：

中国南方改造型盆地的特点,决定了其油气成藏的复杂性和多样性.以成藏的基础、关键、归宿特殊性的分析、论证为基点,根据:(1)现今油气藏的定位不决定于原型盆地,而与晚期改造,再分配烃源控制的空间有关;(2)主导成藏模式应为早期聚集晚期成藏、晚期聚集晚期成藏两种类型;(3)油气的高演化和晚期成藏的特点,决定了南方应以找气为主;(4)晚期重建整体封存体系的优劣是能否成藏并保存的关键,其核心是建造与改造的统一;(5)南方天然气的储集以多层系、多类型为特点,应坚持"有主要目的层,而不唯主要目的层”,多层兼顾,立体勘探和"二次生烃,多层储集、动态成藏,整体封存”的勘探思路.

Abstract:

The characteristics of the reformed basins in South China determined the complexity and variety of the basins' hydrocarbon pool forming. According to the pool forming basis,the key and end result,it is suggested that:1.the localization of present hydrocarbon pools is determined by late stage reformation, the reservoir spaces controlled by redistributed hydrocarbon source but not proto type basins; 2.the principal pool forming models shoul be early stage accumulation late stage pool forming and late stage accumulation late stage pool forming two kinds; 3.the property of hydrocarbon high evolution grade and late pool forming has determined that gas exploration should be taken as the main target in South China; 4.the quality of late stage reformed and entire sealing system is the key of pool forming and preservation; 5.the exploration of natural gas in South China must insist on the main target horizons and give consideration to other possible gas bearing beds;must insist on the exploration thinking of "secondary hydrocarbon generation, multi bed reservoiring and entire sealing" due to its property of multiple reservoir beds and multiple reservoir types.
