摘要

探讨了川西南部平落坝—邛西地区储层沥青中吡咯类化合物的分布特征和该区须二段储层中天然气的运移方向,指出:平落坝—邛西构造带储层沥青含氮化合物中吡咯类化合物的丰度、异构体参数的绝对大小与相对变化说明该构造平面上运移效应主要是对平落坝地区的吡咯类分布具有控制作用,总体表现出自西向东运移的趋势,而在整个平落坝—邛西构造带,这种控制并不明显;该构造须二段气藏具有原地或近源性,其天然气以大范围内的垂向运移为主。

Abstract

This article discusses the distribution characteristics of pyrrole nitrogen compound in reservoir bitumen and the migration direction of natural gas in the second section of the Xujiahe Formation in the Pingluoba Qiongxi area, southwest Sichuan basin. The analyses of abundance of pyrrole nitrogen compound, absolute size and relative change of isomer parameter in nitrogen commands of reservoir bitumen, etc. indicate that the horizontal migration effect mainly controls the distribution of the pyrrole nitrogen compound in the Pingluoba area, but it is not very significant in the whole Pingluoba\|Qiongxi area. The geological analysis suggests that the Xu2 reservoir is near source and has a large scale vertical migration.
