ABSTRACT Radial jet drilling is an effective technology for mining coal‐bed methane. A self‐propelled bit greatly affects efficiency. Simulations and laboratory experiments using a coaxial straight‐swirling mixed (CSMJ) were performed to study the flow field rock erosion characteristics, analyze laws influencing key structural parameters (straight‐swirling ratio N , slot length–width d r / s mixing chamber length–diameter L q D linear segment f ) on change law of axial velocity under...
A gas diffusion layer (GDL) is an essential component for the efficient operation of proton exchange membrane fuel cells, requiring stable mechanical strength and uniform stress distribution to achieve higher durability. The various microstructure characteristics GDLs have coupled complex effects on properties, which not been fully considered in previous studies. In this study, we combined stochastic reconstruction techniques, explicit dynamics compression simulation, orthogonal design...
Tight gas reservoir (TGR) plays an important role in unconventional oil and resources. The existing seepage models for TGR rarely consider the effects of heterogeneity, stress-sensitivity, unsteady fluid exchange between matrix fracture. Heterogeneity is common tight which should be carefully considered geological model. stress-sensitivity effect fracture factor influencing transient flow behavior TGR. Ultra-low porosity permeability cause fractures systems. So this paper introduced a...
Abstract Plant fiber reinforced polymer composites (PFRPs) in practical application are often subjected to both complex friction and variable temperature environments. The present work explores the possibility of reinforcing rice husk/polyvinyl chloride (RH/PVC) with basalt fibers (BF) for developing a new wear resistant material improved thermal stability. results showed that structural strength resistance increased at first then decreased an increasing ratio BF/RH, highest value occurred...
The CC 5005 aluminum alloy was cold-rolled to different reductions and then annealed at 537 °C for 1 h under pressures. changes in microstructure, mechanical property texture were investigated. results showed that high-pressure heat treatment significantly refines the recrystallized grain, refinement effect is enhanced with increasing rolling reduction. grain leads an increase yield strength, ultimate tensile strength hardness of sheet, but a decrease elongation. also has significant on...
The hot band of CC AA 3003 aluminum alloy was cold-rolled to different reductions, and then annealed at 482 °C for 1 h under pressures. evolution microstructure texture investigated. High pressure heat treatment can refine recrystallized grains weaken pinning effect. average grain size decreases from 205.17 μm 73.54 with the increasing atmosphere 6 GPa. In meanwhile, aspect ratio increases 0.18 0.72. Compared pressure, fine precipitates (50–150 nm) disappear after pressurization, number...
The Al1060/Al6061-TiCp/Al1060 laminated composites were successfully fabricated by combining powder metallurgy and hot rolling. A subsequent T6 treatment was employed to optimize the mechanical properties of composites. through-thickness inhomogeneity microstructure texture observed in Al1060 layer. In hot-rolled composites, surface layer suffered shear deformation, r-cube developed at After treatment, recrystallized grains near exhibited a reduced size compared those interface....
To better evaluate the production performance of tight oil reservoirs, it is urgent to solve multistage fractured horizontal well enigma. It paramount develop new models analyze for reservoirs. In this paper, a prediction model in reservoir was established. model, unsteady transfer flow between fracture and matrix considered. This solved by using Laplace transform method, line source function Stehfest method comprehensively. The type curves including pressure transient analysis rate were...
Radial jet drilling (RJD) technology is applied to low permeability oil-gas reservoirs, coalbed methane, and shale gas. A self-propelled bit an integral component. The external flow fields of a new-type straight–swirling integrated (SSIJ) were tested under non-submerged conditions the key parameters studied in this paper. rock-breaking experiment at specific target distance was conducted verify PIV test results. It indicated that, from introduction central straight jet, low-axial-velocity...
Abstract Scientific investigations on the non-chemical modification of lignocellulosic fibers are important for engineers when they design green wood-plastic composites. Two types fibers, namely rice husk and straw were studied. The physicochemical thermal properties with without seawater compared. results suggested that improved it specifically increased surface roughness, crystallinity, pyrolysis temperature at 5% weight loss, decreased silicon, hemicellulose, lignin content fibers....
Abstract The use of radial jet drilling (RJD) to exploit unconventional natural gas is an attractive study area. A self‐propelled bit enormously affects the efficiency.
