- W2358146363 abstract "For the problem of oil well sucker rod pump subsurface failure is difficult to be automatically diagnosed,a rod-pumping unit fault diagnosis method based on Matlab that integrates grid method and grey theory to judge pump condition types is proposed.First,six eigenvalues of the standard dynamometer cards' grey matrix are calculated and its database is established.Then,six eigenvalues of the field measurement dynamometer cards' grey matrix are also calculated,and the grey degree of association is measured.Finally,according to the grey degree of association,the degree of approximation between the standard dynamometer cards and the field measurement ones is determined,automatically identifying the pump condition types with Matlab program by itself.The proposed method is helpful to enhance the efficiency of oil production,realize the intelligent control of remote oil production and construct digital oilfield." @default.
