摘　　要：近年来,柴窝堡凹陷的勘探显示出深层二叠系具有良好的油气勘探前景,但目前对于凹陷东南缘研究匮乏,沉积特征认识不清,沉积相类型存在较大的争议。通过对其东南缘剖面露头岩石相分析,建立不同地层分布的沉积相柱状剖面,研究地层横向上的可对比性,识别纵向中—下二叠统地层发育的沉积相类型:下二叠统发育冲积扇、扇三角洲沉积,中二叠统发育滨浅湖沉积,在此基础上提出适用于研究区的冲积扇—扇三角洲—滨浅湖相沉积体系,对该地区今后沉积的研究及野外勘探具有一定的指导意义。In recent years,the Chaiwopu basin shows deep Permian has good oil and gas exploration prospect,but in the southeast margin of the basin is fort nest sag with sedimentary facies and sedimentary characteristics of research in Permian is lack of systemic and there is a big controversy.Through to nest fort area for fine sedimentary characteristics of the southeast margin of multiple profile description,and speculated that the sedimentary environment,identified there is a set of different sedimentary types of below-middle Permian:in the development of below Permian continental alluvial fan-fan delta deposit,the middle Permian shore shallow lake-half deep lacustrine facies.On this basis,the alluvial fan delta fan shore shallow lake depositional system suitable for the study area was put forward,which has certain guiding significance to the exploration of this area.
