含油气盆地分析的思路和流程

文章从油气勘探的目的出发,提出了多学科、多参数进行含油气盆地分析工作的思路和流程。该流程把含油气盆地分为13种要素,它们之间存在着相互依存、相互影响的内在联系。含油气盆地分析,就是利用多种方法和手段对盆地进行整体解剖,找出各要素间的内在联系规律,建立盆地三维空间随时间演化的模式,从而找出油气演化与分布规律,指出有利勘探区块和有利圈闭。

THE THINKING AND FLOW CHART OF PETROLEUM BASIN ANALYSIS

Sedimentary basin analysis is becoming a course paied close attention extremly by geolo-gists, as an independent course. This course is gradually maturing to reach the condition to solve specialproblemes, with synthezing various geological courses. In resent years, the research and practice on thisway are in full swing. However, the author applies different guiding thinking and working proceduce,on the basis of different standpoints and specialzeed needs. This text gives an idea suitabe for petroleumbasin analysis flow chart starting with the objective of petroleum prospecting. In this flow chart, the petroleum basin is distinguished to shirteen essential factors in terdepedenteand infuence each other. Petroleum basin analysis is dissecting basin as a whole, to make use of mani-flod method and means, discover the inherent laws of every factor, set up the basin model changinginthree-dimensional spece with epoch, further more dissover the laws of petroleum evolution and distri-bution and suggest favoudrable areas and traps.
