| 摘 要： | 在岩芯观察的基础上,结合地震资料和测井资料对该区馆陶组粗碎屑岩进行了详细的研究,认为该套粗碎屑岩属湿地冲积扇沉积。进而分析了馆陶组湿地冲积扇的岩性特征、古气候特征、微相类型,并总结出了这种冲积扇的沉积模式。在此基础上,进一步阐明了基准面旋回对沉积相纵横向展布的影响.

| Abstract: | According to core observation, the coarse clastic rock in the area is studied in detail with seismic data and well logging date. The result shows that the coars e clastic rock is formed in wet alluvial fan. The lithologic character, geolog ic climate feature and the types of micro-facies in the Guantao Formation are analyzed and the models of facies are also concluded in this paper. Through detailed study, the paper further illuminate that the base level cycle has effec t on sedimentary facies. |
