摘要
运用流体势理论分析了塔里木盆地满加尔凹陷及周围地区主要储层中的油气运聚条件，指出封闭或半封闭的低势区因具多方汇油条件最有利于油气聚集；做出了奥陶系、石炭系及三叠系储集层在不同地质历史时期油势的低势区分布图。据此，结合油源、储层分布等特点，分析了油气运移和聚集条件，并指出了有利聚集区。
The migration and accumulation of hydrocarbon in main reservoirs from Manjar Depression and its adjacent districts may be studied by way of the theory of fluid potential.It is suggested that the seal or partly seal area of relatively low potential of oil best benefits hydrocarbon accumulation,as oil from multi directions could be collected over there.By means of the distributions of relatively low oil potential area on the top of Ordovician,Carbonferous and Triassic System during several geologic periods,in addition to characteristics on oil source and reservoir,the conditions of migration and accumulation are being analysed,and the favorable areas of hydrocarbon are demonstrated respctively.
