Analysis of the application for the magnetohydrodynamic effect in the hydrocarbon production

Abstract

Nowadays the main share of oil fields is at a late stage of operation. It is characterized by high water cut of the extracted products. Salts in the formation fluid, under certain thermobaric conditions, settle on the process equipment and they cause its failure. Failure of technological equipment entails the well’s downtime and high material costs. Water-soluble salts in the formation fluid are subject to electrolysis. There, the molecules of the substance are decomposed into ions. The Lorentz force acts when a magnetic field is applied to the ions. The magnetohydrodynamic effect is manifested in the formation fluid. The purpose of the article is to analyze the applicability of the magnetohydrodynamic effect for hydrocarbon production. The chemical composition of formation waters for some deposits is given. On its basis the chemical model for electrolysis of the main salts in sodium chloride and potassium chloride contained in the formation liquid is constructed. The design and operation principle of the simplest magnetohydrodynamic pump is considered. The description of the developed laboratory sample of the magnetohydrodynamic pump is given. The main conclusions are reflected in this article.
