Abstract

Система для уменьшения перепада давления, связанного с турбулентным потоком флюида через трубопроводы, расположенные в удаленных местах (например, глубоко под землей и/или глубоко под дном моря). Такое уменьшение перепада давления осуществляется путем транспортировки реагента для снижения гидравлических потерь через длинный трубопровод небольшого диаметра и последующего нагнетания реагента для снижения гидравлических потерь в залегающий в породе флюид в удаленном месте для получения обработанного флюида. Затем обработанный флюид извлекается из удаленного места с помощью трубопровода, предназначенного для добычи/транспортировки. Присутствие реагента для снижения гидравлических потерь в обработанном флюиде уменьшает перепад давления, связанный с потоком через трубопровод, предназначенный для добычи/транспортировки.A system for reducing the pressure drop associated with turbulent fluid flow through pipelines located in remote locations (eg, deep underground and/or deep seabed). This pressure drop reduction is accomplished by transporting the hydraulic loss reducing agent through a long, small diameter pipeline and then injecting the hydraulic loss reducing agent into the underlying fluid at a remote location to obtain a treated fluid. The treated fluid is then removed from a remote location via a production/transport pipeline. The presence of a hydraulic loss reducing agent in the treated fluid reduces the pressure drop associated with flow through the production/transport pipeline.
