Using artificial neural networks for pattern recognition of downhole dynamometer card in oil rod pump system
The present paper shows that by using Artificial Neural Network system one can establishes pattern classes and sets standards for training and validation in Dynamometer Card in oil well rod pump systems. Also, the design and the implementation of a features extractor are then possible by the study of descriptors.
متن کاملPattern Recognition for Downhole Dynamometer Card in Oil Rod Pump System using Artificial Neural Networks
This paper presents the development of an Artificial Neural Network system for Dynamometer Card pattern recognition in oil well rod pump systems. It covers the establishment of pattern classes and a set of standards for training and validation, the study of descriptors which allow the design and the implementation of features extractor, training, analysis and finally the validation and performa...
متن کاملModified Dynamometer.
RENEWED interest in ophthalmodynamometry during recent years has revealed difficulties in the actual technique which may be attributable, at least in part, to the dynamometer in common use, designed by Bailliart (1917). Many of these troubles have their origin in the lack of control over the instrument that is so frequently experienced. This is especially common when the operator is in the earl...
