摘　　要：从磁化率各向异性特征被发现以来,众多学者开始越来越多的运用这种方法来研究地质问题,特别是在构造地质学、沉积学以及第四纪环境等方面得到广泛应用,本文集中总结阐述运用磁化率各项异性的方法来恢复沉积物沉积时的沉积动力最新研究成果、存在的争议问题及新的研究方向,此外在研究沉积动力之前确定载磁矿物也是至关重要,确定磁性矿物的种类和粒径是岩石磁学研究的基础,因为不同的磁性矿物具有不同的意义的磁化率各项异性特征。According to the standard of small scale division of Upper Paleozoic in Sulige gas field,based on the characteristics of the small layers in the study area,according to the lithology and electrical characteristics of each layer and the sedimentary environment of the study area,the detailed comparison and division of the Shan 1 st member and He formation 8 th member,the division of study area stratum is more reasonable and meticulous,it lays the foundation for the research and analysis of the reservoir in the study area. According to the result of small layer division,the stratum of study area has the following characteristics,the average height of Shan 1 st member is 51. 2 m,The thickness of the three stratum in the Shan 1 st member is about 16 m,the average height of He formation 8 th member is 71. 4 m. From the comparison section of skeleton,Whether it is East-West or north-south direction,the thickness of Shan 1 st member and He formation 8 th member are relatively stable,just in Local well point,because of the large proportion of sandstone and the existence of differential compaction,There are some differences in formation thickness.
