一北部湾盆地乌石凹陷东部地区流沙港组烃源岩孢粉相特征及其意义
Palynofacies of source rocks of Liushagang Formation in East Wushi Depression, Beibuwan Basin and its significance
摘要
Abstract
Using the palynofacies analyzing method,this article first studied the origin and formation environment of organic matter of the source rocks in Liushagang Formation of Paleogene, Wushi Depression, and then evaluated the hydrocarbon generation potential of the region. The results show that the source rocks originated from low salinity lakes, and the bottom and top of the El2 oil shale formation correlate with the culmination of the lakes. For the El3 and the mudstone of the middle part of El2 , the biogenic origin is mixed. For the oil shale of El2 , the biogenic origin is the aquatic organisms. Lastly for the El1 , the biogenic origin is the higher plants. The hydrocarbon generation potential of the source rocks is mainly influenced by the amorphous organic matter( AOM) content of the oil shale of El2 , whose AOM content is the highest, has the greatest hy-drocarbon generation potential, the E13 takes the second place, while the El1 has the least potential.关键词
