为了确定准噶尔盆地米东区二叠系芦草沟组烃源岩有机质类型及其生烃方向、生烃潜力，对其烃源岩干酪根显微组分、元素组成和岩石热解参数进行了研究。分析表明准噶尔盆地米东区芦草沟组烃源岩有机质类型好，包括大量的腐泥型和腐殖-腐泥型有机质，是形成于深湖、半深湖相还原环境的富有机质沉积，有大量来源于低等水生生物和浮游藻类的母质输入。由于湖底浊流的影响，各段烃源岩混入较多的陆源高等植物母质，形成大量的混合型有机质。米东区芦草沟组各段烃源岩均具有较好生烃潜力，但由于其演化阶段处于生油窗内，主要生成石油，可能是良好的页岩油储层，页岩气情况不容乐观。

In order to determine the types of organic matter in Midong District in Junggar basin in Permian Lucaogou Forma-tion hydrocarbon source rocks and hydrocarbon generation direc-tion and hydrocarbon generation potential of the hydrocarbon source rock, kerogenmaceral, elemental composition and rock pyrolysis parameters is studied. Analysis shows that the organic matter in Junggar basin of Midong Lucaogou Formation source rock type is good, including sapropel and humic-sapropelicor-ganic matter a lot, is formed in a deep lake, semi deep lake fa-cies of the reductive environment rich in organic matter deposi-tion, a large number ofsources in the lower hydrobiont and phy-toplankton, the parent material input. Because of the influence of sublacustrine turbidite, terrigenous sections of hydrocarbon source rock mixed with more higher plant parent material, to form a hybrid large amounts of organic matter. Midong Lucaogou Formation section of hydrocarbon source rocks have better hydro-carbon potential, but because of itsstages of evolution in oil win-dow, mainly to generate shale oil, may be a good reservoir. shale gas, the situation is not optimistic.
