【摘要】 为评价海拉尔盆地烃源岩生烃能力,采用自制的“内加热压实式模拟实验装置”,对海拉尔盆地的两个煤岩样品进行热压模拟实验,并对模拟产物进行了系统定性及定量分析。以实验数据为基础,计算出煤化作用各阶段的视煤气发生率,并将褐煤煤化作用分为三个演化阶段,对各阶段煤岩的演化特征及演化机理进行了探讨。更多还原

【Abstract】 Two brown coal samples from Hailaer Basin are heated to different temperatures inlaboratory using simulating experimental equipment made by ourselves in this paperProducts of simulating experiment are analysed qualitatively and quantitatively. The re-sults indicate that brown coal coalification of experimental simulation is similar to natu-ral evolution of brown coal. Based on gas generation quantity of simulating experiment,coal gas generation rate Ra (m~3/t) of each evolution stage is calculated. Brown coal coal-ification is divided into three evolution stages depending on characteristics of products ofsimulating experiment, and evolution mechanism of each stage has been primarily stud-ied.更多还原
