摘要
中国南方扬子板块志留系广泛发育富有机质海相页岩层,相比较而言华南板块桂中柳城北区块石炭系页岩勘探处于起步阶段,为深入剖析石炭系页岩富集规律,通过沉积学、地球化学、储集特征和含气性等进行分析研究。结果表明,石炭系鹿寨组下部普遍发育下斜坡相一台盆相页岩沉积,富硅质混合质页岩相和富泥硅质页岩相具有较高成熟度、较高孔隙度、较好含气性特征,页理纹层发育,具有较好的勘探开发前景。
In southern China,the Silurian system of the Yangtze Plate is extensively developed with organic-rich ma-rine shale layers.In comparison,the exploration of Carboniferous shale in the northern block of Luicheng in the cen-tral Guangxi basin of the South China Plate is in its infancy.To deeply analyze the enrichment patterns of Carbonifer-ous shale,this study conducts analyses through sedimentology,geochemistry,reservoir characteristics,and gas con-tent.The results show that the lower Carboniferous Luzhai Formation is commonly developed with slope-basin shale sedimentation,and the rich siliceous mixed-lithology shale and argillaceous siliceous shale facies exhibit high maturity,higher porosity,and better gas-bearing characteristics,with well-developed laminae,indicating a good prospect for exploration and development.
