中文摘要:
      四川盆地上二叠统发育的龙潭组泥页岩分布广泛,具有成为下一套页岩气主要产气层位的潜力。在总结近年来川东南地区龙潭组研究现状的基础上,通过野外剖面研究、测井资料解释以及室内显微薄片等方法,结合研究区内龙潭组泥页岩的发育特征,对沉积相对泥页岩厚度特征及泥页岩组合特征的影响进行了研究。结果表明,川东南地区泥页岩组合及厚度受控于沉积环境:滨岸相主要泥页岩组合为泥岩夹砂岩,最厚;潮坪相主要泥页岩组合为泥岩夹砂岩,有效厚度仅次于滨岸相;混积陆棚相泥页岩组合以泥岩夹灰岩为主,较薄。
英文摘要:
      The Longtan Formation shale developed in the upper two Permian of Sichuan basin is widely distributed, and has potential to become the next main gas producing horizon of shale gas. On the basis of summarizing the research status of Longtan Formation in the east of Sichuan Province in recent years, through field profile research, logging data interpretation and indoor microscopic thin slices, combined with the development characteristics of mud shale in the Longtan Formation in the study area, the influence of the sediment shale thickness characteristics and shale combination characteristics is studied. The results show that the shale assemblage and thickness are controlled by sedimentary environments in southeastern Sichuan. The main shale assemblage of littoral facies is mud-encased sand, the thickest. The main shale assemblage of tidal flat facies is mud pack sand, and the effective thickness is only inferior to the shore facies. The shale assemblage of mixed continental shelf facies is mainly covered by mud and ash. There is no shale assemblage in the basin facies. It has a certain significance to further discuss the influence of sedimentary environment on the development characteristics of shale.
