We have investigated the geologic features of the lower Cambrian-aged Niutitang Shale in the northwestern Hunan province of South China. Our results indicate that the Niutitang Shale has abundant and highly mature algal kerogen with total organic carbon (TOC) content ranging from 0.6% to 18.2%. The equivalent vitrinite reflectance (equal-Ro) value is between 2.5% and 4.3%. Mineral constituents are dominated by quartz and clay. The average quartz content (62.8%) is much higher than that of clay minerals (26.1%), and this suggests a high brittleness index. Organic-matter pores, interparticle pores, intraparticle pores, interlaminated fractures, and structural fractures are all well developed. The porosity ranges from 0.6% to 8.8%, with an average of 4.8%, whereas the permeability varies from 0.0018 to [Formula: see text] (microdarcy) (averaging [Formula: see text]). The porosity of TOC- and clay-rich shale samples is generally higher than that of quartz-rich shale samples. The gas adsorption capacity of the Niutitang Shale varies from 2.26 to [Formula: see text], with a mean value of [Formula: see text]. The TOC content appears to significantly influence gas adsorption capacity. In general, TOC-rich samples exhibit a much higher adsorption capacity than TOC-poor samples.

The Given

Adsorption capacity is a fundamental property of shale gas content that is vital to estimation of the shale gas in-place, which is controlled by organic matter (OM) and clay mineral (CM). The adsorption behavior of CM is easily neglected because of the capacity of OM is much more powerful. In this study an improved Langmuir model with adsorbents which including OM, CM and other minerals (Oth) based on adsorption experiments results on four mudstone samples in Northern Songliao Basin was set. The given Langmuir volume (VL) and Langmuir pressure (PL) are applied to geological conditions in terms of the empirical formula. Results show that adsorption capacity of CM account for 30% ~ 70% which cannot be ignored in continental lake basin in OM-rich shale (TOC=1%~6%). The verifications for the new model with experimental results in other basins are correct and reliable. Therefore, a new method could be used to predict adsorption capacity of shale reasonably.
