准噶尔盆地西北缘红山嘴车排子地区含油气系统划分

Petroliferous System Division of Hongshanzui-Chepaizi Area in the Northwest Margin of Junggar Basin

准噶尔盆地西北缘红山嘴-车排子地区(简称红车地区)石油地质条件复杂,油气来自于沙湾凹陷的3套烃源岩、构造演化主要经历了挤压和拉张两个阶段,在考虑上述条件的基础上综合储层、盖层、圈闭等多个因素,将红车地区划分为3个含油气系统:P-C(!)含油气系统,P-P、T、J(!)含油气系统,P、J-N(!)含油气系统。在此基础上,根据含油气系统间的相互关系划分出一个复合含油气系统:沙湾复合含油气系统;根据含油气系统内部含油气区带间的差异又将P-C(!)和P-P、T、J(!)两个含油气系统分别划分为两个亚含油气系统。

The petroleum geological conditions were complex in Hongshanzui-Chepaizi Area in the northwest margin of Junggar Basin,where oil and gas came from three sets of source rocks in Shawan Depression.Its structural evolution was mainly experienced two stages of compression and extension activities.On the basis of comprehensive consideration of above factors including reservoir,caprock,trap and many other factors,the area was divided into three petroliferous systems,such as P-C petroliferous system,P-P,T,J petroliferous system and P,J-N petroliferous system.On the basis of the petroleum system division and according to the interrelation between the petroliferous system,a composite petroliferous system is divided: that is the Shawan Composite Petroliferous System;based on the differences between petroliferous areas,the two petroliferous systems P-C and P-P,T,J are divided into two subsets petroleum systems.
