1. Translation of Spe paper
1 DFN encapsulation model was constructed to generate some disc-shaped fractures based on their statistical characteristics. The DFN model proposed in the construction process includes two streams. One group is a wide aperture for fractures, with the fluid working as the main flow path. Another approach is to reduce the aperture for fractures, with work serving as the primary storage fluid. In each flow, the DFN encapsulation mode is defined by applying fractal theory and geostatistics to fracture the scale and spatial distribution, respectively. The overall DFN model combines two types of DFN encapsulation patterns. At that time, the DFN encapsulation mode will be transformed into a continuum model and equivalent permeable block based on cubic law and evaluation of fluid flow behavior. The distribution of cracks and observation curves have been successfully analyzed for gas reservoirs since 1996. A total of approximately 8000 meters of electric drilling images were measured from 11 wells to understand the fracture system. According to the suggested process, the DFN encapsulation mode is constructed. The evaluated DFN model simulates a single pore type through flow simulation by comparing the simulated pressure derivative curve with the measured curve. Observing the pressure derivative curve as a concave curve resembling a dual medium behavior, but the curve never reaches the second unit. By studying the statistical characteristics of parameters, including the granularity distribution and spatial distribution of fractures, the observation curve was successfully replicated
2. English introduction about Dongjiang, such as geography, length, resources, current situation, water usage, etc
Dongriver flows through provinces: Jiangxi and Guangdong. Basin area: 32275 square kilometers. The length of Dongjiang River is 523 kilometers, with a basin area of 25325 square kilometers and a flow rate of 700 cubic meters per second.. flows through province, jiangxi, guangdong basin area: basin area of 32275 square kilometers dongjiang length is 523 kilometers, the valley area of 25325 square kilometers, flow 700 m3 / s. The air water vapor resources in the upper reaches of Dongjiang River are about 186.4 billion cubic meters, and the actual precipitation formed by nature is 57.8 billion cubic meters. Excluding consumption such as evaporation and underground infiltration, the available water volume is 28 billion cubic meters, accounting for only 15% of the air water vapor resources. It can be seen that the development and utilization of air water vapor resources in this region have great potential. The dongjiang river upstream of the regional air about 186.4 billion cubic meters of water resources, by the natural form of the actual precipitation 57.8 billion cubic meters, remove evaporation, underground permeates and consumption, available water quantity is 28 billion cubic meters, accounted for only 15% of the water resources in the air. The area is the development and utilization of water resources in the air has great potential.
