摘要

摘要: 随着鄂西黄陵背斜南翼震旦系陡山沱组全球最古老页岩气的首次发现，该层系暗色页岩的含气性已获得证实。通过宜昌-秭归地区黄陵背斜南翼秭地1井岩心现场含气量解析和岩矿分析，获得了黄陵背斜南翼震旦系陡山沱组暗色页岩含气量和密度数据；通过区域地震资料处理解释和秭地1井、秭地2井钻井标定层位，获得了有利区含气页岩厚度及分布，明确了含气页岩的体积；通过概率体积法对该区陡山沱组页岩气资源量进行计算，其范围为（845.78~3 029.08）×10⁸ m³，中值资源量为1 947.27×10⁸ m³，证明该层系具有良好的页岩气资源潜力，可作为鄂西地区下一步页岩气勘探的重点区域。

Abstract: With the first discovery of the world's oldest shale gas in the Sinian Doushantuo Formation on the southern limb of the Huangling anticline in the western Hubei Province, the gas-bearing properties of the dark shale in this layer have been confirmed. The gas content and density data of the dark shale of the Sinian Doushantuo Formation in the study area were obtained by gas content and rock and mineral analyses of the core samples from the well ZD-1. Based on the interpretation of regional seismic reflection profiles and well data of ZD-1 and ZD-2, we delineated the distribution and thickness variation of the black shale in detail, and defined the volume of the gas-bearing shale. The resource potential of the Lower Sinian Doushantuo Formation on the south limb of the Huangling anticline was determined by the probabilistic volume method. The gas resource was calculated, ranging (85-303)×10⁹ m³, and the median resource was 195×10⁹ m³, which indicates that the layer has a good shale gas resource potential. It was recommended as a shale gas exploration target in the western Hubei Province.
