Abstract Aiming at the problems of leakage and scraping of conventional oil logging flow collectors, an overall scheme of electric extruded rubber flow collector with rubber elastomer as the core is proposed. The finite element method and the Mooney-Rivlin hyperelastic constitutive model are used to simulate the rubber elastomer and study the influence of its shape, geometry and material properties on the flow collection performance. Moreover, an electric extruded rubber flow collector is developed and its flow collection performance is tested on a simulated well test rig. Experimental results demonstrate that the structure, hardness, friction coefficient with the pipe and the concave degree of the rubber have a significant influence on the performance of the collector; The rubber flow collector with hardness 58HA, size 80mm × 12mm, 4mm internal concavity and rounded internal concave elastomer has better flow collection performance than conventional umbrella type flow collector.
