Abstract: After analysing the basic petroleum geolegic conditions of Junggar, Tarim, sichuan Basin and their major hydrocarbon bearing areas, we prove that the formation and its development of a hydrocarbon bearing basin is closely related to the regional tectonics and its evolution. Within a basin, the existance of structural elements, sources, reservoirs, seals and sedimentary conditions et al., follows a certain order each. Thus, the regularity of oil and gas pools' distribution is brought out from foreland to craton basin. The basin is constituted as an organic integrated entity provided with a system of oil pool composition. Under this circumstance, the hydrocarbon bearing basin shoud be treated as a whole one in explorating affairs, and the synthetic three-dimensional alternated exploration is needed emergently.

Key words: hydrocarbon bearing basin, regional structure background, regularity, a system of oil and gas pool composition, synthetic three-dimensional alternated exploration

摘要： 从准噶尔、塔里木和四川盆地及其主要含油气区石油地质基本条件的分析说明含油气盆地的形成和发展与区域构造背景及演化密切相关,盆内构造单元、烃源岩、储集层与盖层沉积条件以及油气藏类型等五个方面均有规律分布,决定了从前陆到克拉通盆地油气藏分布的有序性,并构成以复合油气藏为特征的有机统一整体.勘探实际中需要对含油气盆地整体考虑,实施三维立体交叉式综合勘探.
