胜利油田义东礁丘相碳酸盐岩矿物包裹体的研究

A STUDY OF THE CARBONATE INCLUSION IN THE REEF PHASES IN YIDONG AREA,SHENGLI OIL FIELD

胜利油田义东礁丘是重要的储油岩体。本文研究了该礁丘相碳酸盐岩裂隙及晶洞充填物中包裹体的类型、特征、分布,测定了均一温度、盐度,分析了气相成分、液相成分、气态烃组成,还计算了氧逸度等地化参数。并据所获资料对油气运移、有机质演化及古水体特征等提供了重要信息。

Yidong reef is a main reservoir in Shengli oilfield.This paper gives the results of a detailed study of the inclusions in the fractures and pores in the carbonates in Yidong reef phases.Types,features,and distributions of these inclusions are studied their uniform temperature,satinity are deter- mined,gas constituents,liquid constituents and composition of gaseous hydr- ocarbons are analyzed,and corresponding geochemical parameters,such as oxygen fugacity are estimated also.Data thus obtained give important info- rmations regarding to the migration of oil and gas,evolution of organic matters and characteristic of paleoaquifers.
