| 摘 要： | 阐述了库车坳陷天然气地球化学特征,并应用碳同位素动力学研究结果,探讨了库车坳陷天然气的成熟度和气源.库车坳陷天然气有湿气、凝析气和干气多种类型;天然气具有由西向东、由北向南甲烷含量减少、干燥系数减小的趋势;天然气主要属煤成气,来源于中生界烃源岩.库车坳陷不同构造带天然气的成熟度差异较大,Ro值从0.7%变化到2%以上.克拉2气田天然气Ro值为1.3%～2.5%.综合目前多方面资料分析,库车坳陷天然气的主力气源岩应是侏罗系煤系烃源岩,三叠系烃源岩的气源贡献次之. |

| Abstract: | Geochemical characteristics of natural gas in Kuqa depression of Tarim basin are studied. The maturity and source of gas in the depression is discussed by using the result of carbon isotope kinetics. The gas in Kuqa depression, containing wet gas, condensate and dry gas, appears the trends of both methane content and dryness coefficient decreases from west to east and from north to south. It belongs to coal-formed gas and originates from Mesozoic source rocks. Its maturity in different structural belts is differentiated with Ro ranging from 0.7% to over 2%. The Ro of gas from Kela-2 gas field ranges from 1.3% to 2.5%. It is considered from the comprehensive data analyses that the major source rocks in Kuqa depression should be Jurassic coal-bearing source rocks, while Triassic source rocks make the second contribution to the gas pool in it. |
