Detecção e classificação de modos de operação do bombeio mecânico via cartas dinamométricas. 2014. 173 f.

This work presents a study about a new automatic approach to the detection and the classification of operation mode in the Sucker-rod Pumping through dynamometric cards of bottom hole. The main idea is the recognition of the well production status through the image processing of the bottom s hole dynamometric card (Boundary Descriptors) and statistics and similarity mathematics tools, like Fourier Descriptor, Principal Components Analysis (PCA) and Euclidean Distance. In order to validate the proposal, the Sucker-Rod Pumping system real data are usedapplication/pdfAcesso AbertoDescritores de Contorno. Descritores de Fourier. PCA. Bombeio Mecânico.
