China is a country with the most widely distributed karst, and the karst is extensively developed in its southwesten part where 2,836 underground rivers are distributed with about 1,847.8 x 108 m³⋅a-1 of karst groundwater resources and a total discharge of 479.7 x 8 m³⋅a-1 in the dry season. These underground rivers become the main water source for people's life as well as the development of industry and agriculture in Southwest China. However, water shortage has often occurred in recent years, due to the unreasonable development and utilization of karst water resources. How to make scientific, reasonable and effective use of karst water resources has become a difficult problem in tackling water resource crisis. In this paper, we have studied the hydrological process and numerical simulation of groundwater in karst areas from the perspective of groundwater science, which is of great significance to the accurate evaluation, and rational development and utilzation of karst water resources. In this study, we take Dajing basin, a typical karst peak-cluster depression area in southern Guizhou Province, as the study area. Water-bearing media in karst areas often include karst pipelines with high permeability and dissolved gaps with low permeability. The flow mechanism of groundwater in these two media is quite different. The groundwater in the gap mainly accords with Darcy's law and the laminar flow mechanism, while the groundwater in the karst pipeline is mostly in the turbulent state due to the large flow rate. In the actual situation, the two media are independent of each other, but there is an interrelated process of hydraulic exchange on the boundary. Based on this, we adopt MODFLOW-CFP coupling model to carry out a numerical simulation of Dajing basin. MODFLOW-CFP is a dual-system coupling model based on dual structure theory. MODFLOW-CFP model contains three groundwater flow simulation methods. In this study, CFPM1, the most basic model, is adopted. In this pattern, the traditional groundwater flowing model is coupled with a specific pipeline model. The main purpose is to depict caves, cracks in interstitial space and basaltic aquifer pipes in karst aquifers, where groundwater can be fully or partially filled and flow patterns can be laminar or turbulent. Therefore, a complete simulation of the hydrological process of karst groundwater may help us to grasp the law of groundwater movement in Dajing basin, accurately evaluate karst water resources, and thus promote the rational development and utilization of the resources. The process of using MODFLOW-CFP to establish a mathematical model of groundwater in Dajing basin includes the establishment of porous media model in MODFLOW and pipeline model in CFP. Subsequently, the two models are combined together to identify the model and analyze the water balance, based on the coupling model. Finally, the water resources are evaluated and the mechanism of groundwater migration is studied. In this study, it is found that Dajing basin is a groundwater system with complete recharge, runoff and drainage conditions, and the North-South and the Northeast-Southwest trending structures control the distribution of regional karst aquifers and the development of karst. According to the buried conditions of groundwater and the practical significance of water supply, the main source of recharge in this area is atmospheric rainfall, and the main discharge is the outflow from the southern Dajing basin. Meanwhile, the simulation results show that the exchange capacity between pipes and porous media is 6,719.1 m³⋅a-1, mainly in the upper and middle reaches of Dajing basin. The total recharge water in the study area is 10,977.3 x 104 m³⋅a-1, and the recharge module is 133.495 m³⋅km-2⋅a-1. The rainfall inflow and infiltration accounts for 81.35% of the total recharge, and the total discharge is 10,813.47 x 104 m³⋅a-1, mainly from the outlet of the underground river. Based on the research findings, the migration mechanism of groundwater in Dajing basin is clarified, and new development and utilization of water resources are put forward to address the shortage of local water resources.

Longtan shale is widely developed in Guizhou Province and is an important part of the unconventional natural gas for the development in coal-bearing formations. Some mudstones have special characteristics due to some siderite minerals contained. This paper takes the Upper Permian Longtan shale in the northern Guizhou as an example to examine the coal-bearing mudstone reservoir. Based on the canister desorption, well logs and test results of siderite-bearing mudstones( core samples from LC-1 well), the authors present systematic pore structure, inorganic and Rock-Eval analyses of the mudstones to examine their gas content, reservoir properties, depositional environ-ment and origin. The results show that the Longtan shale contains type Ⅲ gas-prone organic matter with an over-mature stage and has total organic carbon values ranging between 0. 90% and 2. 71%. Carbon isotope data clearly indicate the terrestrial organic matter source dominating the Upper Longtan formation. Desorbed gas content( obtained by canister desorption, dominated by methane) of core samples ranges from 0. 08 to 7. 79 m3/t with an average of 1. 60 m3/t. The mudstones are mainly composed of clays( 35%) and quartz( 15. 7%), and most of them contained high siderite and dolomite with an average of 38. 1% and 9. 5%, respectively. Desorbed gas content of core samples are positively correlated with TOC but negatively correlated with quartz and clay mineral contents, BET specific surface areas and BJH total pore volumes measured by gas injection method, which suggests that the organic matter is the main material source for desorbed gas, but the storage space is not provided by mesopores or micropores. However, the negative correlation between siderite content and specific area with pore volume( obtained by gas injection method), suggesting that the intercrystalline pore of siderite is insufficient to provide the storage space for the occurrence of the desorbed gas. The distribution of siderite around the organic matter is stratified, botryoidal, lenticular or tuberculous, and the stratigraphic continuity remains intact. The siderite surrounding the organic matter, as analogous to a "micro-trap"inside the mudstone, blocks the hydrocarbon gas migration in the organic matter. This may be the main reason for the positive correlation between desorption and siderite content. The organic matter always adsorbed and stored the hydrocarbon gas generated and sealed by"micro-trap". With the increase of organic matter and"micro-trap", the amount of enclosed gas increases. The sideritebearing mudstone with filled gas may further reach as an overpressure reservoir for a certain pressure gas sealing. Furthermore, the siderite-bearing mudstone can have independent "micro-gas system"for the lacking of gas migration and exchange with adjacent coal seams. The reducing conditions during the deposition of Longtan formation for the response of elemental geochemical index is closely interrelated to the fluctuation of sea level, indicating that the typical sedimentary environment provides favorable conditions for the siderite. The desorbed gas, siderite and organic carbon content change regularly with the process of sea level falling and rising from bottom to top of the Upper Permian, indicating that the siderite and organic matter deposited in tidal flat-lagoon with relatively stable Eh and p H values and limited water circulation. The high ferric ions brought into by sand interstitial water chemically react with reducing gas from the reduction of organic matter to create hydrocarbon gas. The gas sealed by "micro-trap"is stored as adsorbed gas on organic matter, suggesting a controlling effect on the desorbed gas of siderite-bearing mudstone. [ABSTRACT FROM AUTHOR]
