摘要/Abstract

摘要： 黔南地区寒武系牛蹄塘组厚度大，底板地层封闭性相对较好，可分为两段，其中第一段为半深水-深水陆棚相黑色碳质页岩夹粉砂岩，厚度为99m，是主要的页岩气目标层段；第二段为浅水陆棚相灰色粉砂岩、页岩，厚165m。针对黔南地区仅有的一口牛蹄塘组页岩气调查井——麻江地区麻页1 井取样分析，显示该井牛蹄塘组第一段页岩TOC 在0.39%~5.35% 之间，镜质组反射率（R_o）在1.56%~2.48% 之间，平均为2.06%，干酪根显微组分以腐泥无定形体为主，为Ⅰ型干酪根；岩石主要由石英和黏土矿物组成，脆性矿物含量较高，一般大于50%，孔隙度在1.13%~1.88% 之间，渗透率一般为0.0011~0.0082mD，表现为低孔、低渗的特征；总含气量最高可达1.13m³/t。该调查井初步揭示黔南地区寒武系牛蹄塘组页岩地质条件较好，具有进一步深入开展页岩气调查勘探的潜力。

Abstract: The Cambrian Niutitang Formation in southern Guizhou is very thick, and has well-developed floor with relatively effective sealing capacity. This formation can be divided into two sections. The first section, the primary target of shale gas, is composed of black carbonaceous shale of semi-deep and deep water continental shelf facies interbedded with siltstone, 99 m thick. The second section is composed of gray siltstone and shale of shallow-water continental shelf facies, 165m thick. Sampling analysis was made on Well MY-1, the only shale gas exploratory well drilled within the Niutitang Formation in southern Guizhou. The results show that the black shale in the first section of the Niutitang Formation reveals the TOC of 0.39%-5.35%, the vitrinite reflectance (R_o) of 1.56%-2.48% (2.06% on average), and the Type I kerogen with maceral dominated by amorphous sapropelites. The rock contains quartz and clay minerals, with higher content of brittle minerals (generally higher than 50%). Both the porosity and the permeability are low, 1.13%-2.23% and 0.0011-0.0082 mD, respectively. The total gas content is up to 1.13m³/t. Well MY-1 reveals that the Cambrian Niutitang Formation in southern Guizhou has better geological conditions for shale gas reservoirs, and large potential for further exploration of shale gas.

Key words: southern Guizhou, Niutitang Formation, black shale, organic geochemistry, reservoir properties, gas content
