摘要:

通过分析、对比鄂尔多斯盆地和渤海湾盆地67个来源于石炭系—二叠系煤系天然气的组分、稳定碳同位素组成,并结合实际地质背景分析,取得以下认识:鄂尔多斯盆地和渤海湾盆地来源于石炭系—二叠系烃源岩的天然气绝大部分是煤成气,靖边气田少量油型气来源于二叠系太原组灰岩。鄂尔多斯盆地天然气主要为干气,而渤海湾盆地天然气主要为湿气。鄂尔多斯盆地20%天然气样品发生倒转,主要倒转形式为δ13C213C 3高成熟阶段生成;渤海湾盆地石炭系—二叠系煤成气主要是成熟阶段的产物,少量天然气为烃源岩在高—过成熟阶段所生成,这部分天然气主要分布在东濮坳陷。成熟度和母质组成的差异使得2个盆地甲烷碳同位素组成存在差别,随着成熟度的增加,2个盆地重烃气与甲烷碳同位素差值逐渐减小。

Abstract:

Through analysis and comparison of the gas chemical and stable carbon isotopic compositions of 67 gas samples sourced from the Carboniferous-Permian (C-P) coal-measures between the Ordos Basin and the Bohai Bay Basin,combining with the geological condition analysis,conclusions are obtained as follows:Most of the gases are coal-derived gas,and the little amount of oil-type gases in the Jingbian Gasfield in the Ordos Basin were generated by the Permian Taiyuan Formation limestone.Most of the gases in the Ordos Basin are dry,while the ones in the Bohai Bay Basin are mainly wet gas.Carbon isotope reversals (i.e.δ13C213C3 ) happened to 20 percent of the total gas samples in the Ordos Basin.While up to 27% of the total gas samples in the Bohai Bay Basin have the carbon isotope reversals,and δ13C313C4 is the main type.Both the carbon isotope reversals in the two basins were caused by the mixture of coal-derived gases of different maturities.The gases in the Ordos Basin were mainly generated by the mature to high-mature source rocks of C-P coal measures.The gases in the Bohai Bay Basin were mainly generated by the mature C-P source rocks,and a little part of the gas were derived from the high-over mature C-P source rocks,and these gases are mainly produced in the Dongpu Depression.The maturity and the organic matter composition are the main controlling factors which caused the δ13C1  difference of the gases in the two basins.The values of δ13C213C1  andδ13C313C1 decrease with the increasing of the thermal maturity of the source rocks showing the carbon isotopic values of methane and its homologues become more and more close as the gas-generating process.

Key words: Carboniferous-Permian, Coal-measure, Coal-derived gas, Carbon isotope, Ordos Basin, Bohai Bay Basin
