摘要

本文着重从微观角度对川西坳陷中段上三叠统天然气运移的相态进行研究,认为本区天然气的运移经历了水相-气、水两相-气相的相态转换,为正确认识该区油气富集的规律及勘探目标提供了依据.

Abstract

In this paper,study is focused on the facies patterns during the migration of the Upper Triassic natural gas in the middle part of the West Sichuan Depression from microcosmic angles.It is suggested that the migration of natural gas in this area have experienced water-vapor+water- vapor facies pattern transformation.This provides basis for the correct understanding of regularities for hydrocarbon enrichment and exploration targets in this area.
