摘要:

塔里木盆地是在古生代地台基础上发展起来的中—新生代叠合型含油气盆地.由于盆地长期处于相对稳定的大地构造环境,这就为油气的生成、聚集、保存提供了有利的地质条件。从盆地内发现的多处地面油气显示和目前钻井获得的高产油气流,都证实了塔里木盆地的油气资源是非常丰富的。特别是在盆地内发现的多套生油层来中,寒武—奥陶系为最佳。为此,本文就从寒武—奥陶系的石油地质特征入手,来探讨油气的分布规律。

Abstract:

Tarim Basin is a Mesozoic—Cenozoic superimposed oil—bearing basin developed from the Paleozoic platform. As it has long been in relatively stable tectonic setting,it provides the favorable geologic conditions for oil—gas generation,accumulation and preservation. A lot of oil and gas seepages and the prolific oil—gas wells indicate that Tarim Basin is rich in oil—gas resources. Among the mufti—oil—generating beds,the Cambrian and Ordovician is the best one. According to the Cabrian and Ordovician petroleum geologic features,the author analyzes the oil—bearing potential in the basin.

Key words: Tarim Basin, Cambrian system, Ordovician system, Source rock, Source—Reservoir— cap assemblage, Trap
