Shale Gas Organic Geochemistry Characteristic of the Mesoproterozoic Xiamaling Formation in Western Beijing Area

Abstract:

Recently, the position of shale gas is more and more important in the world energy structure. The lithology of Xiamaling Formation in Beijing area mainly include siltstone, silty shale and shale. The organic carbon content is relatively high, averaging 2.28%. The kerogen type of organic matter is dominated by II₁ and II₂ types, and thermal evolution level is relatively high, averaging 2.05%. Intergranular micropore is well developed, and most of the micropore diameter is 1-7µm, so the reservoir condition is good. The content of the brittle mineral is relatively high, so it can be easily fractured in production. The content of the clay mineral is relatively high, so it has a good adsorption capacity. Through wild prospecting and geochemical analysis for samples, this paper systematically assesses the Xiamaling Formation shale in Beijing area, which can provide basic stata for further shale gas study in Beijing area.
