accumulative roll bonding (arb) was used to fabricate the cu-zn multilayer and cu-zn solid solution. a lamellar structure with the hardness of about 130 vhn was formed after eight arb cycles. following to the suitable heat treatment, a solid solution with a uniform microstructure and hardness of about 57 vhn was produced. the dominant wear mechanism in the arb processed multilayer was found to ...

Abstract The interlayer interference is very serious in the process of water flooding development, especially when reservoir adopts commingling production. implementation various mitigation measures requires that production performance parameters and remaining oil distribution each layer should be clearly defined, accurate splitting wells key. In this paper, five-spot pattern simplified to a si...

Multilayer networks are a useful way to capture and model multiple, binary relationships among a fixed group of objects. While community detection has proven to be a useful exploratory technique for the analysis of single-layer networks, the development of community detection methods for multilayer networks is still in its infancy. We propose and investigate a procedure, called Multilayer Extra...

through a collection of cooperative agents called ants, the near optimal solution to the multi-reservoir operation problem may be effectively achieved employing ant colony optimization algorithms (acoas). the problem is approached by considering a finite operating horizon, classifying the possible releases from the reservoir(s) into pre-determined intervals, and projecting the problem on a grap...

An integrated hydraulic fracturing followed by waterflooding was conducted in a heterogeneous sandstone formation the Northern Shanxi Slop of Ordos Basin Western China. Water breakthrough quickly occurred, and underlying mechanism water has not been well understood. Such needs to be investigated comprehensively from spatial connectivity multilayer sand bodies characterization hydraulic-natural ...

in this paper, the rolling force and reduction ratio have been investigated in multilayer strip rolling. for this purpose, two different set of multilayers have been selected which are al/st/al and cu/al/cu layouts. at first, the validation of the numerical analysis was performed by using an experimental test. after validation of the numerical results, two set of multilayer layouts were simulat...

On the basis of generalization experience in development multilayer high-viscosity fields X influence waterflooding late stage on oil recovery factor productive formations has been studied. By applying statistical methods data processing dependence reservoir flushing factor, with a sufficiently high correlation coefficient, obtained. The obtained confirms theoretical from developed and can be u...
