Sequence stratigraphy characteristics and coal accumulation law in Mid-Lower Jurassic in southwest Tarim
-
摘要: 为了研究塔里木盆地西南缘（简称塔西南）中-下侏罗统煤炭聚集规律，在综合分析前人研究的基础上，利用野外露头剖面、钻井、测井、岩心等资料，以岩性特征、岩相变化等指示，进行了沉积相划分和层序地层格架的建立。塔西南中-下侏罗世地层以冲积扇、扇三角洲、三角洲、湖泊和沼泽相为主。通过分析沉积相组合特征、沉积界面特征及展布，识别出2个二级层序界面，4个三级层序界面。结合聚煤盆地沉积演化特征，认为盆地稳定沉降扩展期为煤层发育的有利期，对应于湖侵和高位沉积体系。最后，根据层序控煤理论和钻遇煤层厚度展布特征，分析了克孜勒陶凹陷、叶城—和田凹陷与和田布雅凹陷内的聚煤规律。Abstract: In order to clarify coal accumulation law in Mid-lower Jurassic in southwest Tarim, through the procedures of comprehensive analysis of previous studies, using profiles, drilling, well logging, core materials, by facies changes directions, identifying sedimentary facies and establishing sequence framework, fan, fan delta, delta, lakes and swamps sedimentary facies were identified. By systematic analysis the types of sedimentary facie, sedimentary boundary characteristics and distribution, two sequence boundaries and four sequence boundaries were recognized. Combining sedimentary and evolution characteristics, stabilized settlement expansion stage was benefitial for coal accumulation, corresponding to the transgressive and high deposition system. Finally, according to the theory of sequence structure type of coal and the characteristics of coal seam thickness distribution, the coal accumulation law in Kizilayao depression, Yecheng-Hetian depression and Hetianbuya depression was identified.
