Pulsed discharge is a promising approach for producing non-thermal plasma at atmospheric pressure. Pulsed power generators vary widely in performance and should be chosen according to the application requirements. In this paper, a repetitive microsecond-pulse generator was constructed using a cascading of power modules, where all solid-state switches were considered as the key units. The generator...
Considering the high cost and long term of field experiment with high concentration polymer flooding and the irreversibility of reservoir development process, in order to ensure the best development results of the production block, a numerical simulation study was carried out in this paper to calculate the high concentration polymer flooding development programs of Xing-5 polymer drive pilot area...
This paper focuses on the stability of complex dynamical networks with general topology. Compared with the previous work, the outer and inner coupling matrices of complex networks are considered to have no restrictions. Control of such networks is investigated by applying the local feedback to a fraction of nodes. The Master Stability Equation (MSE) derived for complex networks contains the spectrum...
According to the fact that starting up pressure gradient exists when fluids flow in low permeability reservoir, a concept called effective driving coefficient is introduced to this paper,the recovery ratio calculation formula of low permeability is proposed, and also the formula is revised by using the effective driving coefficient, on that basis, the authors establishes an economic evaluation model...
According to the fact that starting up pressure gradient exists when fluids flow in low permeability reservoir, a nondarcy flow mathematical model is established, in which the factor of starting up pressure gradient is included for low permeability reservoir. Software, by solving the partial differential equations by difference method, is developed, and is used to calculate development index and the...
