Self-contained process module with flow swirling for downhole equipment power supply

Abstract

The present paper is dedicated to the development of resource-saving technologies for oil and gas complex, namely to the development of power supply for downhole equipment. The relevance of this research is caused by the acute lack and high electricity costs for downhole devices which are widely-used both in drilling and in hydrocarbon production. The traditional methods used to power these devices, namely batteries and power cables are unreliable and short-lived and they require capital and time expenditure for production process, tripping operations, etc. shutdowns. There is a solution to this problem consisting in use of autonomous downhole power supply system including a hydrodynamic module with an electric power generator which converts well flow energy. An assessment of the device operability was made in which its high performance is highlighted.
