塔里木盆地塔东凸起西部中上奥陶统地震层序与海底扇沉积 - At present , important breakthroughs have been gained in the middle - upper ordovician . oil and gas were mainly storaged in the karstic fissure - cave . thus , the study of karstic reservoir are very important
塔河油田下奥陶统是其主要产油层位，目前在中上奥陶统又取得了突破，油气主要储存在岩溶缝洞中，因此岩溶型储层研究具有非常重要的意义。 - The carbonate source rocks of middle - upper ordovician in tarim basin are widely distributed in different sedimentary environments at the same period such as platform margin slope , platform inner sag , continental shelf , abyssal basin , etc
摘要塔里水盆地中上奥陶统碳酸盐岩烃源岩在同一时期不同的沉积环境（台缘斜坡、台地内凹陷、陆棚、深海盆地等）中均有发育。 - According to the differences of sedimentary facies and environment , the source rock are divided into four types such as lime - mud reef in platform margin , platform inner sag , deep - water flat slope or continental shelf , abyssal basin , the lime - mud reef type is distributed in platform margin of upper ordovician , the remained three types are widely distributed in cambrian - ordovician system
根据沉积相带与沉积环境的不同，可将烃源岩划分为在不同沉积环境中的4种类型烃源岩；台地边缘灰泥丘型烃源岩、台地内凹陷型烃源岩、深水缓坡与陆棚型烃源岩、深海盆地型烃源岩。
