摘要
在对川西南雷波等区块地表出露的上奥陶统五峰组-下志留统龙马溪组观察和取样分析测试的基础上,研究四川盆地及周缘五峰—龙马溪组页岩沉积相、空间展布、有机地化、泥页岩物性及岩石物性、成熟度等页岩气地质条件特征。样品分析数据和研究表明,该套泥页岩具有厚度大、有机碳高、成熟度高和含气量高等特点,具备页岩气藏发育的良好地质条件。
Through observations,sampling and laboratory analyses of five areas and three well black shale outcrops in Sichuan Basin and periphery,we studied shale-gas geologic condition of the upper Ordovician –lower Silurian black shale,such as precipitation facies,distribution,organic,physical property of the black shale etc.Research shows that its periphery is characterized by great thickness,abundance of organic carbon,high maturity and elevated gas content,being capable of good geological conditions for shale-gas reservoir development.
