To investigate the influence of mesoscopic heterogeneity and confining pressure on mechanical properties granite under cyclic loading, a series biaxial compression tests were conducted samples with different mineral crystal size distributions using Particle Flow Code (PFC) software. A grain-based model was established to explore effects distribution-induced heterogeneity, pressure, loading rock mechanics parameters. The damage mechanism analyzed from microscopic perspective. results showed...
The mechanical properties and failure characteristics of coal have a significant impact on the efficiency coalbed methane extraction. Cleat structures, which are widely distributed in reservoirs, exert notable influence behavior coal. In this study, coal-like specimens with various cleat structures were fabricated using three-dimensional printing technology, uniaxial compression tests conducted to investigate effects quantity, angle, combination experimental results reveal that as quantity...
Mold level fluctuation has always been one of the key factors in slab quality control. Abnormal fluctuations can easily cause slag entrainment and form surface defects hot-rolled cold-rolled steel sheets, thus reducing product qualification rate. In this study, mold data was collected during Ti-bearing Interstitial Free (IF) a stable state for complete casting sequence certain factory. The is analyzed using discrete wavelet transform (DWT) method, its characteristic values are classified...
Bedding structure and strong tectonic compression of deep shale reservoirs have a great influence on the vertical propagation hydraulic fractures proppant transportation, posing severe challenge for fracturing design. A combined experimental numerical study was carried out to investigate in laminated shales. As supplement physical experiment method, flow-stress-displacement-damage coupling method based continuum mechanics developed, which can effectively simulate complex fracture geometries...
The existence of gravels in the glutenite formations leads to complex geometries hydraulic fracturing propagation and difficult construction engineering. To study law formations, this paper establishes a fracture model for heterogeneous based on discrete element method, analyzes effects gravel content, particle size, distribution, horizontal stress difference, fluid viscosity flow rate behavior. Results show that fractures can lead generation branched bifurcation. Small-sized have little...
Natural fractures and cavities are the primary spaces for oil gas accumulation in fracture-cavity carbonate reservoirs. Establishing connection between these wellbore through hydraulic fracturing treatment is important extraction from such Due to discontinuity heterogeneity of existing natural system, anticipating viability troublesome. A new method simulate propagation reservoirs proposed based on continuous damage theory. The considers random spatial distribution can arbitrary expansion...
Abstract To reduce near wellbore fracture complexity in continental laminated shales, in-plane perforations completion technology is introduced. The global embedded cohesive elements are capable to simulating arbitrary propagation growth while the laminae effects on path can be considered established finite element model. Numerical simulations reflect that existence of weak micro fractures only locally alter but change greatly. Furthermore, in-situ stress anisotropy, pump rate, perforation...

Abstract Shale gas development by hydraulic fracturing in Southern China highlights the features of high fracture pressure and serious difficulties proppant placement due to deep burial (over 4000 m). This scenario differs from that North America. To solve problems described above, conventional triaxial tests were conducted on properties rock mechanics under a simulated temperature reservoir environment. A full-size 3-D finite element method (FEM) is used predict shale formation, taking both...
