页岩气是一个很有潜力的非常规油气勘探新领域，资源丰富，属于“持续式”聚集的非常规天然气。目前我国还没有大规模开展页岩气的资源评价。对雪峰山西侧地区埃迪卡拉系陡山沱组碳质页岩的厚度、总有机碳含量、有机质类型、成熟度、裂缝、孔隙度、渗透率、矿物组成、深度及烃源岩生烃强度等页岩气藏因素进行了研究分析。结合陡山沱组地层对比以及岩相古地理特征，利用页岩气“甜点”的评价体系，指出雪峰山西侧地区埃迪卡拉系陡山沱组页岩气的有利勘探区为桑植-石门复向斜及宜都鹤峰背斜区，可以作为雪峰山西侧地区页岩气的战略突破区。

Shale gas is an unconventional resource with great exploration potential and continuous accumulation. At present, our country has not carried out large-scale shale gas resource evaluation. The accumulation factors such as TOC, organic matter type, maturity, crack, porosity, permeability, brittle mineral content, thickness and depth of shale, and hydrocarbon potentials are analyzed in this paper. Based on the study of stratigraphic correlation and paleogeographic characteristics of the Doushantuo Formation, and the key parameters for shale gas sweet spots, the results suggest that the Sangzhi-Shimen synclinorium and the Yidu Hefeng anticline zone are the most favorable areas for shale gas exploration which will become strategic breakthrough areas in the western Xuefeng Mountain.
