摘要

应用岩心、钻井和地震资料,通过剖析准噶尔盆地腹部地区典型隐蔽油气藏实例,研究其成藏机理与油气分布,建立了准噶尔盆地腹部地区隐蔽油气藏的成藏模式.根据其油气藏圈闭表现特征、分布、油气水关系以及形成机理的不同,将准噶尔盆地腹部地区隐蔽油气藏进一步划分为泥岩隔挡型、低幅构造背景型、岩性尖灭型和地层岩性型等4类油气藏类型.

Abstract

Based on core,well drilling and seismic data,typical subtle reservoirs in the Central Junggar Basin are studied.Accumulation pattern of the reservoirs is set up according to their accumulation mechanism and hydrocarbon distribution.Due to the differences in trap characteristics,distribution,relationship among oil,gas and water,as well as formation mechanism,the subtle reservoirs are divided into 4 types:mudstone barrier,low-amplitude tectonic background reservoir,lithologic pinching and stratal pinch-outs.
