摘　　要：研究苏里格气田二叠系下石盒子组盒8段砂体展布以及优势储集体,提高对其含气性的整体认识,提升水平井的实施效率。采用了岩性对比法、沉积旋回法、测井特征分析法、厚度类比以及高程对比等方法,对苏里格气田S区盒8段进行小层精细划分对比。理清了盒8段砂体展布、叠置关系及连通性特征为盒82下段砂体最为发育,在平面上分布具有较好的连片性,盒81下、盒82上段、盒81上段砂体发育面积明显减小。砂体展布是影响水平井实施效果的关键因素,储层物性次之。水平井实施优选区应为在空间上有一定展布规模,砂体连通性、物性均较好的区域。On the purpose of improving the overall understanding of the He 8 reservoir gas and enhancing the efficiency of the implementation of horizontal wells and research of Permian Xiashihezi He 8 in Sulige gas field sand distribution and the dominant group of reservoir. Some methods are used for the comparison of the region of small layer fine-grained of He 8 such as the lithological contrast,sedimentary cycle method,logging feature analysis,the thickness of the analogy and elevation contrast etc. The results showed that the comprehension of the sand distribution,sand overlying relationship and connectivity features of He 8 is that the He 8 under paragraph 2 is the most developed in the plane and a good distribution of contiguous property,He 8 under paragraph 1,He 8 up paragraph 2 and He 8 up paragraph 1 on a segment significantly reduced sand development area. Therefore,the sand distribution is the key factor which affects the implementation of the effect of horizontal wells,followed by reservoir properties. The preferred area for the implementation of the horizontal wells should be the one that has a certain size distribution of sand body with better connectivity and physical properties.
