摘要

摘要: 目前桂中坳陷下石炭统鹿寨组展现出较好的页岩气勘探前景，但页岩中碳酸盐矿物含量较高，异于国内主要页岩气层的碳酸盐矿物含量，其碳酸盐矿物成因及其对页岩气产气的影响未知。文章以桂融页1井及其野外剖面为研究对象，运用X-全岩衍射、岩石薄片鉴定等手段，发现鹿寨组页岩中碳酸盐矿物以方解石为主，含量为5%~80%，平均为 30.33%，并含少量白云石（0%~9%），平均为2.1%，碳酸盐矿物主要发育在炭质页岩、钙质泥岩、粉砂质钙质泥岩、生屑炭质泥岩、泥微晶灰岩和泥质灰岩中以及顺层分布的方解石脉、穿层的构造方解石脉中。在此基础上进一步开展阴极发光、碳氧同位素分析，发现碳酸盐矿物成因主要为海水中原地正常沉积成因，其次为海水中随海浪、风暴流打碎后异地搬运成因以及成岩期重结晶成因，水平脉状方解石的形成可能为埋藏期差异压实收缩缝被地层流体充填后过饱和沉淀，而垂向脉状方解石与多期构造活动有关。

Abstract: The Carboniferous was significant for the development of "black strata" in the world. The exploration and development of shale gas in North America first began with the Carboniferous marine shale, and the Carboniferous (Mississippian) Barnett Shale has become one of the most important strata of shale gas production in the world. The distribution of Carboniferous marine shale in China is relatively limited, primarily developed in the Qian–Gui rift basin at the edge of the Yangtze plate. It is roughly distributed in depressions such as central Guangxi–Nanpanjiang in Guangxi, south Guizhou–southwest Guizhou, and central Hunan. In recent years, drilling activities in the Carboniferous depressions, such as Guirongye Well 1 and Qianziye Well 1 have yielded promising shale gas displays. In 2023, Guirongye Well 2 achieved industrial gas flow from the Carboniferous after the compression fracture was completed, indicating favorable exploration prospects. The Carboniferous strata in the Guizhou–Guangxi region are anticipated to become the next significant exploration target in China, following the shale gas of Wufeng–Longmaxi formation. However, drilling in this area revealed a rapid phase transition in the early Carboniferous, unstable distribution of shale, high levels of carbonate minerals within the shale, and the presence of common carbonate rock interlayers. On-site experiments on water invasion and gas logging suggest that shale gas production is influenced by carbonate minerals in the shale. The origins of these carbonate minerals in the shale of this region and their impact on gas production remain unclear.To this end, the Luzhai formation shale of the early Carboniferous in the depression of central Guangxi was selected to analyze the origin of carbonate minerals within the shale. This study aims to provide theoretical reference for predicting distribution of various types of carbonate minerals in the subsequent shale formation, as well as for gas content analysis and the optimization of the lower Carboniferous shale gas "sweet spot" in the depression of central Guangxi. The study area is situated in the Liucheng slope in the northern depression of central Guangxi. Field profiles and core samples from Rongye Well 1 were utilized as the research objects. Following the identification of carbonate mineral types, geochemical analyses of cathodoluminescence and carbon and oxygen isotopes were conducted. This was achieved through a comprehensive approach including X-ray whole-rock diffraction, thin section identification, and other analytical tests.Research findings indicate as follows, (1) The study found that the carbonate minerals in the Luzhai formation shale are primarily composed of calcite, with a content ranging from 5% to 80%, averaging at 30.33%. Additionally, there is a small amount of dolomite, varing from 0% to 9%, with an average of 2.1%. Carbonate minerals are mainly developed in carbonaceous shale, calcareous mudstone, silty calcareous mudstone, bioclastic carbonaceous mudstone, mud-microcrystalline limestone, and muddy limestone. They are also present in calcite veins distributed along the layers and in structural calcite veins that traverse the layers. (2) Cathodoluminescence analysis shows that massive calcareous mudstone and horizontally laminated micrite carbonate minerals are generally non-luminescent. Some carbonate minerals in silty calcareous mudstone emit weak red light, while others do not. The luminescent carbonate minerals include calcareous cements and certain calcareous bioclastics. The "floating" carbonate bioclastics found in carbonaceous shale typically emit weak red light. Lens-shaped and vein-shaped calcite exhibits weak cathode luminescence. (3) Analyses of carbon and oxygen isotopes show that the δ¹³C values of native carbonate minerals range from 2.70‰ to 5.81‰, with an average of 4.68‰. The δ¹⁸O‰ values range from –8.89‰ to –5.97‰, with an average of –7.54‰. For allochthonous carbonate minerals, the δ¹³C values range from 2.62‰ to 4.39‰, with an average of 3.30‰, and the δ¹⁸O‰ values range from –8.89‰ to –7.67‰, with an average of –8.04‰. The δ¹³C‰ values of diagenetic vein-shaped carbonate minerals range from –1.18‰ to 5.73‰, with an average of 2.78‰, while the δ¹⁸O‰ values range from –12.76‰ to –5.75‰, with an average of –9.77‰.Comprehensive exploration shows that the formation of carbonate minerals primarily results from normal sedimentation in seawater, followed by long-distance transport in seawater after being fragmented by waves and storm currents, and recrystallization during diagenesis. The formation of horizontal vein-shaped calcite may be attributed to supersaturated precipitation within differential compaction and contraction fractures filled by formation fluids during burial, while the vertical vein-shaped calcite is associated with multiple tectonic activities. Based on these findings, various models of carbonate mineral genesis have been established, providing theoretical reference for the optimal selection of sweet spots for shale gas in the lower Carboniferous depression of central Guangxi.
