Characteristics of Peculiar State Mineral in Oil-Gas Bearing Province in Northern Margin of Qaidam Basin

Abstract

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
