Abstract

The objective of the present project is to develop a linear tubular motor for the operation of an oil pump for application in petroleum extraction systems. The goal is to offer an alternative to the traditional form of extraction, which consists of a complex system whose mechanical characteristics make extraction impracticable in low production wells or at the wells running out of crude oil. One of the characteristics of the system is that the linear tubular motor must have pulsating movement and must be designed in a modular form, facilitating underground assembly. Its choice is justified by the feature of linear movement and by the absence of mechanical contact between the fixed part (which operates) and the mobile part (which is operated), thus eliminating mechanical losses characteristic of the traditional operation. Basically the work involves three fundamental tasks: the mechanical dimensioning of the pump and of the pumping system; an electromagnetic study of the linear tubular motor, where the electromagnetic structure of the motor will be defined; the electrical calculation and construction of a prototype, simulation of the operation and thermal performance, and the development of an electronic operating system.
