摘要

作者以有机地球化学常规分析、岩屑气及天然气组份、轻烃指纹、碳同位素等对川西凹陷侏罗系天然气的气源问题进行了对比和分析研究。研究结果认为该天然气主要来自上三叠统上盆组合。

Abstract

Based on the conventional analysis of organic geochemistry, and debris gas, components of natural gas, fingerprints of light hydrocarbon, and carbon isotopesetc.,the gas source of the Jurassic natural gas in the west Sichuan Depression, the Sichuan Basin is studied and correlated in this paper. It is suggested that the gas in the depression was mainly derivd from the T3x4-T3x5 assemblages.
