摘要： 介绍了柴达木盆地北缘油气区沉积地层中特态矿物的特征,总结出特态矿物在油气层上方的分布规律及其8种主要集合体类型。研究了特态矿物的交代现象、包容关系、与油质沥青的伴生关系、扫描电镜下的特征和x-衍射分析结果。阐述了高产油气层(井日产油量大于10t),一般产量油层(井日产油量1~10t)和仅见油气显示(或极低的产油量)层上方特态矿物的主要特征。

Abstract: The characteristics of peculiar state mineral in oil deposits in the northern margin of Qaidam basin are presented. The distribution of this mineral on oil zones and its eight types of aggregates are ilustrated. The replacement, inclusion and association to oily asphalt as well as feature from scanning electron microscope (SEM) and X-ray analytical result of the peculiar state mineral are studied. Particularly, the characteristics of this mineral on high-yield zone (over 10t per day per well), normal-yield layer (1-l0t per day per ell) and only oil-gas show or extremely low oil production bed are revealed in this paper.

Key words: Qaidam basin, mineral, characteristic, oil-gas zone
