Abstract

Раскрыты комбинированное устройство для регулирования и ограничения водопритока и его трубчатый фильтр. Комбинированное устройство для регулирования и ограничения водопритока содержит комбинированный трубчатый фильтр для регулирования водопритока. Комбинированный трубчатый фильтр для регулирования водопритока содержит базовую трубу (1); самонастраивающееся устройство (3) для регулирования притока, установленное на базовой трубе и используемое как канал циркуляции для жидкостей внутри и снаружи базовой трубы и регулирования степени открытия канала циркуляции согласно изменению вязкости различных жидкостей, чтобы автоматически ограничивать поток; устройство (4) для регулирования расхода, установленное на базовой трубе рядом с самонастраивающимся устройством для регулирования притока для регулирования перелива базовой трубы; и трубчатый фильтр, расположенный соосно и соединенный резьбой с базовой трубой, причем внутренний диаметр трубчатого фильтра такой же, как у базовой трубы. Комбинированное устройство для регулирования и ограничения водопритока и его трубчатый фильтр может автоматически регулировать поток жидкости согласно характеристикам жидкости, приводить к балансу профиля притока, выполнять легкое и простое в работе активное регулирование водопритока и обеспечивать установившуюся нефтедобычу, и при этом обеспечивать эффективность его функций в отношении регулирования водопритока и увеличения нефтедобычи в течение всего периода добычи из нефтяной скважины.Disclosed is a combined device for regulating and limiting water inflow and its tubular filter. The combined device for regulating and restricting water inflow contains a combined tubular filter for regulating water inflow. The combined tubular filter for water inflow control contains a base pipe (1); a self-adjusting inflow control device (3) installed on the base pipe and used as a circulation path for liquids inside and outside the base pipe and adjusting the opening degree of the circulation path according to the change in viscosity of various liquids to automatically restrict the flow; a flow control device (4) installed on the base pipe next to the self-adjusting inflow control device for controlling the overflow of the base pipe; and a tubular filter located coaxially and threaded with the base pipe, and the inner diameter of the tubular filter is the same as that of the base pipe. The combined water control and limitation device and its tubular filter can automatically adjust the fluid flow according to the characteristics of the fluid, balance the inflow profile, perform easy and simple operation active water control, and achieve steady oil production, while ensuring the effectiveness of its control functions. water inflow and increase in oil production during the entire period of production from an oil well.
