摘要
本文为了对两淮石炭三叠煤系的生烃性能做出评价,进行了比较系统的有机地化方面的基础研究,包括有机碳沥青A族组分、气相色谱、红外光谱、有机元素、热解色谱、热解气相色谱、碳同位素、天然气甲烷碳同位素和色谱质谱分析等。三百多个煤层和泥岩样品采自淮北煤田的宿县、临焕和濉肖矿区以及淮南煤田的淮南和谢矿区的不同井田和占孔,煤级范围R^0max介于0.63—1.24％之间,属低质气煤到肥煤牌号。
ln order to estimating on hydrocarbon generation Potentials of Permo - carboniferous coal measures in Huainan and Huaibei coal fields systematic basic study has been made in organic geochemistry which include organic carbon, bitumen A, family component, gas chromatography,infrared spectrometry, organic elements, pyrography, pyrolysis gas chromatography, isotopes of carbon, isotopes of carbon in natural gas and methane, chromatography and mass spectrometry analysis etc. Three hundred or over samples ( coals and mudstones)were collected from mines and drill holes of Suxian, Linhuan, Sueixiao, mining area Huaibei coal field and pan-xie, Huainan mining area Huainan coal field. The coal Rank ( R0max% ) is between 0.63 and 1.24, so it's low metamorphic gas coal to fat coal. Analysising has made shown that the dispersed organic matter of coal measures as well as coal seams are humic source material and type Ⅲ kerogen basically,but there are some features of type Ⅱ in varying degree; C-P coal measures and seams are good source rocks of generating-gas in Huainan and Huaibei coal fields
