布曲

布曲期为广海碳酸盐台地环境；

In Middle Buqu period , there was an open sea carbonate plateau .

因此，布曲组是盆地内最好的油气勘探目的层，沿中央隆起带两侧以及北羌塘地区的琵琶湖&半岛湖凸起一带应是油气勘探的有利区带。

The best oil-gas exploration belt is along both sides of the central uplift belt and the belt from Pipa Lake to Bandaohu Lake .

笔者从有机质丰度、有机质类型、有机质成熟度，尤其是生物标志物特征等方面揭示了北羌塘盆地侏罗系布曲组烃源岩地球化学特征。

This paper reveals the geochemical characteristics of the source rocks on the basis of the abundance , types and maturity of organic matter , and especially biomarker analysis .

北羌塘盆地发育的布曲组海相碳酸盐岩是重要的烃源岩之一，但是由于研究程度低，一些油气地球化学问题尚不清楚。

It is the one of the most important source rocks for the Buqu marine carbonate rocks in North Qiangtang Basin , but some issues about oil and gas geochemistry are not clear because the lowly research .
