摘要：

依据地震、测井、地球化学及古生物标志可以鉴定和识别密集段。密集段因其沉积环境相对稳定,生物种类众多,有机质丰富,因此可作为地层对比的钥匙。密集段多为重要的油气源岩和区域盖层。吉尔嘎朗图凹陷依据上述标志可划分出5个不同的密集段,皆具一定的生油气能力。

关键词: 密集段, 识别标志, 地质意义, 吉尔嘎朗图, 凹陷

Abstract:

Condensed section could be identified according to seismic data,well log, geochemical and fossil markers. Since its deposition environment was relatively stable, the species of orgomisms are various and organic matter is rich enough, the section could be taken as a key in stratigraphic correlation. It has been proved in practice that this kind of sections are usually important source rocks or regional cap rocks. According to the above mentioned markers, the Jiergalangtu Depression could be divided into five condensed sections with considerable oil generation potential.
