依据海相碳酸盐岩成烃特征探讨中扬子地区油气勘探前景

DISCUSSION OF THE PERSPECTIVE OF OIL EXPLORATION IN MIDDLE YANGTZE AREA FROM THE HYDROCARBON GENERATION OF MARINE CARBONATE ROCKS

从碳酸盐岩有机质丰度的下限评价标准入手,探讨了碳酸盐岩作为烃源岩的评价问题,并结合中扬子地区海相地层的发育特点,从烃源岩的角度分析了该区海相地层的油气勘探前景。

In the base of the evaluative criterion of the threshold value of organic abundance of carbonate rocks, this paper discussed thoroughly the evaluative problems of the value of organic abundance ,Combined with the development characteristics of marine strata in middle Yangtze area ,and from the point of view of source rock, we placed emphasis on analyzing the perspective of oil exploration of marine strata in this area.
