The increasing demand for natural gas energy will promote unconventional gas, such as coal seam and shale to play a key role in future development. mechanical properties of seams are weaker compared with conventional reservoirs. fluid–solid coupling phenomenon exists widely at the pore scale macro seams, runs through whole process coalbed exploitation. objective this study is establish microscale gas–water flow model methane considering fluid structure coupling. Frist, used scanning electron...
Tight reservoirs are subsurface formations with extremely low permeability, in which a high resistance to flow can be expected while developing hydrocarbons. Typically, obtain economic production rates from such reservoirs, multistage fractured horizontal wells (MFHWs) necessary. During reservoir development, the mutual coupling effect between fluid and stress fields cannot ignored. In this study, discrete fracture model (DFM) was proposed simultaneously simulate deformation behaviors. The...
Irregularities in microphone distribution enrich the diversity of spatial differences to decorrelate interferences from beamforming target. However, large degrees freedom irregular placements make it difficult analyse and optimize array performance. This article proposes fast feasible optimal design methods with improved performance for human speech. Important geometric features are extracted be used as input vector neural network structure determine arrangements sensors. In addition, a...
