Abstract：The shale gas resource is rich in northeastern Guizhou Province,and especially,the Lower Cambrian Niutitang Formation has great exploration potential. Based on the data of several drilling wells,combined with the data of outcrops and their geochemistry characteristics,we studied the characteristics and main enrichment controlling factors of the shale gas of the Lower Cambrian Niutitang Formation in northeastern Guizhou Province. The shale is characterized by great thickness,wide distribution,high content of organic carbon,higher thermal evolution degree and good reservoir conditions,etc. However,most wells met the phenomena of low gas content,low methane content and high nitrogen content. Upon the system analysis of main enrichment controlling factors,it is considered that the shale gas enrichment of the Niutitang Formation in study area has distinct characteristics of distribution zone controlled by sedimentary facies and reservoir controlled by fault.
