    • 摘要: 应用全岩有机岩石学分析方法,对库车坳陷北部山前带中生界三叠系和侏罗系烃源岩的显微组分、主要富氢组分、有机质类型及热演化程度进行了研究.结果表明:库车坳陷北部山前带侏罗系克孜勒努尔组烃源岩显微组分总含量最高,恰克马克组烃源岩最低.中生界烃源岩显微组分组成具有镜质组含量高、壳质组和惰性组相对发育、腐泥组贫乏的特征.不同层位具有一定差异性,克孜勒努尔组和塔里奇克组中镜质组含量较高,恰克马克组壳质组相对发育.孢子体、壳屑体、角质体和藻类体是其主要的富氢组分,恰克马克组富氢组分相对含量最高.烃源岩有机质类型以Ⅲ型和Ⅱ2型为主,有利于生气,镜质组反射率Ro为0.56%~1.87%,热演化程度处于成熟-高成熟阶段.克拉苏—依奇克里克构造带冲断前缘烃源岩显微组分总含量与热演化程度均相对较高,为烃源岩的最大成熟生烃中心.烃源岩高生烃潜力与高的壳质组含量和低的陆源有机质含量有关.

    • 摘要: 鄂尔多斯盆地北部盒8期为浅水三角洲沉积,具有构造稳定、沉降缓慢、坡缓、水浅等特点;受季节、气候等因素的影响,湖岸线频繁摆动,盒8期湖岸线并不局限于某一条线,而是一个摆动带.为了明确鄂尔多斯盆地北部盒8期古湖岸线的位置,采用有机岩石学方法对盒8段暗色泥岩显微组分特征和有机岩石学特征进行了深入研究,结合盒8段泥岩颜色,综合识别了古湖岸线的位置及其摆动范围.研究认为:三角洲平原相泥岩显微组分以镜质组为主,泥岩有机相为陆地森林沼泽相,前缘相泥岩显微组分则以无定形体组分富集为特征,有机相为覆水森林沼泽相和开阔水体相.苏38井-苏327井-陕9井一线以北为三角洲平原;三角洲前缘可进一步细分为三角洲内前缘和三角洲外前缘,定边-莲4井-陕344井-子洲一线以南为三角洲外前缘沉积.湖岸线摆动带为三角洲内前缘沉积,是天然气勘探的有利目标区.

    • 摘要: 综合运用岩心观察、薄片鉴定、地球化学参数分析等方法,对准噶尔盆地吉木萨尔凹陷吉32井二叠系芦草沟组烃源岩开展了有机岩石学精细研究.结果表明:综合反射光、透射光特征,烃源岩有机质赋存形式划分为有形态有机质、无形态有机质和次生有机质,有机显微组分划分为5组12组分,以腐泥组无结构藻类体和沥青质体为主,次生组含量普遍较高,镜质组和惰质组含量较低,壳质组含量极少;依据有机质组分荧光性、含量、形态等特征,有机显微组分在岩石矿物中具有5种赋存状态,有机显微组分类型及含量具有显著的非均质性,与所赋存的岩石岩性组分、结构、构造具有明显的对应关系;腐泥组无结构藻类体和无定形体等富氢有机组分与有机碳含量和生烃潜力呈正相关关系,为该区主要的生烃有机组分.%Based on the core observation,thin section authentication and geochemical parameters analysis,the detailed study of organic petrology was conducted for the source rocks from the Permian Lucaogou Formation in Jimsar sag of the Junggar Basin.The modes of occurrence of organic matter in these source rocks were structrurally recognized as structural maceral,amorphous maceral,and secondary maceral with the aid of reflected and transmitted light petrography,the organic macerals mentioned above were divided into five groups (sapropelineie,exinite,vitrinite,inertinite,and secondary maceral) and further twelve sub-fractions,which was dominated by unstructural algae and asphaltene,the content of secondary macerals was generally higher,while the contents of vitrinite and inertinite were relative low and exinite occurred in minute amounts.According to the fluorescence,content and shape of organic maceral,the source rocks show strong heterogeneity in the types and contents of the components with respect to rocks types with various lithologies,textures and sedimentary structures.The total organic carbon contents and hydrocarbon generation potential are strongly correlated with the amount of unstructural algae and amorphous macerals,which suggests that unstructural algae and amorphous macerals are major components for the hydrocarbon generation in the Lucaogou Formation.

    • 摘要: This paper evaluates the immature hydrocarbon source rocks in the Qikou sag of Bohai Bay by studying the organic matter abundance of source rocks, the hydrocarbon-generating and-exhausting characteristics,the depositional environment,the organic petrology characteristics,and the characteristics of crude oil.The purpose is to provide the theoretical basis for the evaluation and exploration and development of the immature oil resources in the Qikou sag.The results show that the organic matter of the immature source rocks in the Qikou sag is abundant and good type.Thus, these source rocks have the characteristics of concentratedly generating hydrocarbon and efficiently exhausting hydrocarbon.The hydrocarbon source rocks mainly deposit in a salty environment under a droughty climate.The algae and the mineral bituminous matrix in macerals make a great contribution to the formation of immature petroleum.A large number of immature and low-mature oils are found in the Qikou sag.%利用烃源岩有机质丰度、生排烃特征、发育古环境、有机岩石学及原油特征等手段,探讨歧口凹陷沙一段低熟烃源岩生烃、排烃特征。研究结果表明,歧口凹陷沙一段低熟烃源岩有机质丰度高、类型好,具有集中排烃、高效排烃的特点。沙一下段烃源岩发育的环境主要为干旱气候下的咸水环境。藻类及显微组分中的矿物沥青基质是低熟烃源岩形成低熟油气的物质基础。歧口凹陷存在大量未熟-低熟的原油。

    • 摘要: The stratum of Late Palaeozoic exist in Linxi region , Inner Mongolia of Greater Hinggan southern ar-ea.Dark and thick mudstone layer with potential conditions for hydrocarbon generation and reservoir in Linxi formation of Upper Permian develop well in this region.The feature of maceral , abundance , type and maturity of organic matter of Linxi formation is studied with the method of combining organic petrology and organic geo-chemistry together.The average level of determination of the organic carbon percentage is 0.61%, which shows abundance of organic matter in the mudstone is relatively high.Therefore , the mudstone of Linxi Forma-tion is better hydrocarbon source rock with highly producing ability of hydrocarbons.While the generation abil-ity of hydrocarbon in Linxi Formation mudstone should be gas because of the organic matter type of the mud -stone is mainly type Ⅲand the Organic matter maturity of the mudstone mainly belongs to the high mature to over mature evolutionary stage.%大兴安岭南部内蒙古林西地区发育有晚古生代地层,其中上二叠统林西组发育巨厚层暗色泥岩,具有潜在的生油、储油环境。通过有机岩石学、有机地球化学相结合的方法,对内蒙古林西地区上二叠统林西组泥岩显微组分、有机质丰度、有机质类型以及有机质成熟度进行特征研究。有机碳含量测定结果平均0.61%,表明有机质丰度较高,属于较好烃源岩,具有较强的生烃能力,但由于其有机质类型主要为Ⅲ型,且处于高成熟-过成熟的高变质演化阶段,生烃应主要以生气为主。

    • 摘要: Through comprehensive study on the geochemistry and organic petrology of Niutitang Formation in Sancha,the authors discussed the redox conditions change during Niutitang Formation sedimentary period and its petroleum geologic significance.The study results are as follows:① The trace element redox index V/ (V+Ni) ratio is 0.42-0.92,and its average is 0.71 ;V/Cr value is 0.53-44.50,and its average is 5.34;Ni/Co value is 1.92-23.30,and its average is 7.80;U/Th value is 0.16-15.73,and its average is 4.98;δU value is 0.64-1.99,and its average is 1.50;and the Ce is negative anomaly.The distribution characteristics of redox index in the section reflect that the short oxygenated events such as ocean current upwelling occurred in early Niutitang sedimentary period which is on over reduction condition as a result of transgression,making the sea redox conditions cycle fluctuation.The effects of the aerobic event is lean oxygen environment in the medium term and more for oxidation environment in later term with the sea level' s drop.② Fungi,planktonic algae,benthic macro algae,zooplankton and benthic sponge comprise the hydrocarbon generation organisms.As a result,organic matters are divided into Type Ⅰ and Ⅱ,and the former distribution range is wider than that of the latter which is mainly found in aerobic environment.③ The organic matter abundance is much high,with TOC content average of 6.04%,which in rocks below 120 m are all more than 2% while those over 110 m are less than 2%.Therefore,the shales deposited in reducing environment are thought to have more shale gas potential.%通过湘西三岔地区牛蹄塘组黑色岩系的地球化学和有机岩石学的综合研究,讨论了湘西牛蹄塘组沉积时期氧化还原条件变化特征及其油气地质意义.结果表明:①V/(V+Ni)比值为0.42 ~0.92,平均0.71;V/Cr比值为0.53 ~44.50,平均5.34;Ni/Co比值为1.92 ~23.30,平均7.80; U/Th比值为0.16~15.73,平均4.98;δU比值为0.64~1.99,平均1.50.δCe呈负异常.微量元素在剖面中的分布特征反映牛蹄塘组沉积早期在海侵引起的大范围缺氧还原条件下发生了短暂充氧事件,使得海水的氧化还原条件不断变化.牛蹄塘组沉积早期主要为缺氧还原环境,中期受充氧事件的影响,多表现为贫氧环境,后期随着海平面下降,多为氧化环境.②牛蹄塘组黑色岩系烃源岩的成烃生物母质主要为浮游藻类、底栖宏观藻类、浮游动物、底栖海绵等,有机质类型有Ⅰ型和Ⅱ型之分;Ⅰ型分布区间广,主要分布在还原环境中,而Ⅱ型主要出现于含氧环境中.③黑色岩系TOC含量平均达6.04%,120 m以下的岩石中均>2%,而110 m以上多小于2%,表明牛蹄塘组还原环境下沉积的页岩生烃潜力较大.
