Energy efficiency challenge of waxy oil production by electric submersible pumps

摘要: Abstract In this paper the solid wax formation in two live oils of Samara region fields on five operating pressures with different contents high molecular substances were examined. For both oil samples a linear relation between appearance temperature and pressure was obtained. The study showed inevitable transition from liquid phase to examined under downhole conditions. This fact indicates probability complications during well operations these oilfields. If measures are not put place prevent deposit wells, there is chance complete blockage tubing flowlines by wax. These problems will lead decrease flowrates their shutdown, thereby increasing operation costs remove deposits capital expenditures production. Evaluation conditions for precipitation wells allow develop technology prevention remediation previously formed organic deposits. potential depth minimum flowrate 20 m 3 per day calculated. continuous injection inhibitor designed where has been observed yet proposed.
