成烃理论的发展——（Ⅱ）煤成油及其初次运移模式

近几年来，我国针对侏罗系煤系地层的油气勘探，取得了重大突破。在我国西北区的一些含煤盆地中都发现了丰富油气矿藏。煤成油的勘探开发和研究，是对陆相生油理论的重大发展，本文介绍了秦匡宗提出的一种利用＾１３Ｃ ＮＭＲ谱确定油潜力碳、气潜力碳和芳构碳评价生油气潜力的新方法，以及一种煤成烃的阶段性初次运移模式。

ADVANCES IN HYDROCARBON GENERATION THEORY-(Ⅱ) OILS FROM COAL AND ITS PRIMARY MIGRATION MODEL

In recent years,great achievements have been made in exploring oil and gas from Jurassic coal measure strata in China.Plentiful oil and gas have been discovered in some northwest coal basins of China.The exploration,development and studies of the oils from the coal greatly developed terrestrial oil generation theory.In this article,a new method by Qing Kuangzong was introduced,which adopted (13)C NMR spectrum to determine potential oil-generating carbon (Co),potential gas-generating carbon (Cg),and aromatic carbon to evaluate oil and gas-generating potential.A kind of primary migration model by stages for oil from coal was also presented in this article.
