摘要
本文以现代岩浆火山活动成烃作用和加氢模拟实验为基础，研究和总结断陷盆地烃源岩与火山岩伴生共存的沉积环境和成烃特征，提出了半无机成因天然气的新概念。作者认为火山喷溢－喷流环境是形成低熟高效烃源岩的前提；岩浆火山高温气液对沉积有机物的催化加氢作用是形成半无机成因天然气的条件；由于喷溢－喷流的方式不同，形成了不同类型的半无机成因烃类气。
Based on hydrocarbon formation in modern volcanic activities and Simulation experiments of hydrogenation, sedimentary environmewts and hydrocarbon-generation characteristics of source rocks associated with volcanics in faulted basins were studied and summarized,and the concept of semi-inorganic gases was suggested. The enviroment of volcanic spout and effusion is presupposition essential for low mature sowrce rocks to produce hydrocovrbons effectively;and hydrogenation of magmatic hyperthermal gas-liquid upon sedimentary organic matters is thecondition for the generation of semi-inorganic gases. Due to different modes of volcanic Eruption-effusion. different types of semi-inorganic gases were generated.
