摘要：

川西北上三叠统须家河组是以陆相为主体的含煤碎屑沉积,为目前油气勘探的重点层位之一。探讨其中的油源,除考虑其自身局部生油而外,尤需对其下伏的马鞍塘及小塘子组进行系统的地球化学研究,估价其生油气潜能。为此,我们于1979—1980年对较有代表性的绵竹汉旺剖面,在前人沉积学研究的基础上,系统采集了样品,进行了各种有机质的分析测试。

Abstract:

Maantang formation is of marine limestone,argillite and siltstone,while Xiaotangzi formation is mainly composed of delta-front deposit of tran sition zone from marine to land,rich in marine and terrigenous plant fossils.In the past,they were considered as one of the major source beds in northwestern Sichuan.On the basis of analyses by various mordern apparatus,the author made a study of geochemical features of kerogen in these two formations,we concluded that both of the two formations had been hydrocarbon-generating,but neither of them is a good source rock.In comparison between the two,Maantang formation is better than Xiaotangzi fomation.
