山系、盆地、油气三者之间关系的研究,是油气盆地分析系统工程中的一个重要组成部分。沅麻盆地与雪峰山系,自中、新生代以来,受“板内形变”动力条件控制组成“盆山体系”.造山挤压作用控制了盆地的构造(沉积)格局与油气组合,使盆地发生“构造反转”,破坏或重新调整油气富集条件。作者相信,研究这一区域山系-盆地-油气三者构成的系统,对于南方陆相盆地群的油气评价与找油找气有重要意义。

To study the relationship among mountain system, basin and hydrocarbon is an important (element) in hydrocarbon-bearing basin analysis.The Xiefeng mountain system and the Yuanma basin have been controlled by "intraplate deformation" dynamic condition since the Meso-Cenozoic, and the‘basinmounfain sysfem' wes formed. The orogenic compressional activity controlled basional structural (sedimentary) pattern and petroleum system resulted in ‘structural reversion' of the basin and damage or re-organization of hydrocarbon accumulation. It is very important to study the ‘mountain system-basin-hydrcoarbon' system of the area to evaluate and explore for oil and gas in the continental basins of the South China.
