Abstract
1. Способ добычи вязкой нефти в осложненных условиях, включающий откачку нефти винтовой насосной установкой с поверхностным приводом, закачку в скважину реагента, отличающийся тем, что откачку нефти производят через полые штанги винтовой насосной установки, закачку реагента производят в колонну насосно-компрессорных труб, причем часть откачиваемой смеси нефти и реагента при необходимости возвращают в межтрубное пространство ствола скважины. ! 2. Технические устройства для добычи вязкой нефти в осложненных условиях, включающие поверхностный привод, устьевой сальник, колонну подъемных насосно-компрессорных труб, колонну полых штанг и винтовой насос, отличающиеся тем, что колонна полых штанг, используемая для откачки скважинной жидкости, имеет водоструйную муфту для всасывания специального реагента, расположенную на динамическом уровне скважинной жидкости, и снабжена на верхнем конце двухдроссельным разделителем, размещенным в корпусе, который снабжен шпинделем, снабженным двумя герметизирующими сальниковыми уплотнениями и снабжен двумя неподвижными коническими полостями, в которых размещены соответственно два разделительных дросселирующих конуса, жестко связанных между собой и снабженных регулировочным маховиком, размещенным в герметизирующей заглушке, а нижний конец колонны полых штанг снабжен перфорированной муфтой. 1. A method of producing viscous oil under difficult conditions, including pumping oil with a surface-mounted screw pumping unit, injecting reagent into the well, characterized in that pumping oil through hollow rods of a screw pumping unit, injecting the reagent into a tubing string, wherein part of the pumped mixture of oil and reagent, if necessary, is returned to the annulus of the wellbore. ! 2. Technical devices for the production of viscous oil in difficult conditions, including surface drive, wellhead stuffing box, tubing string, hollow boom string and screw pump, characterized in that the hollow boom string used for pumping the wellbore has a water-jet clutch for suction of a special reagent, located at the dynamic level of the borehole fluid, and is equipped at the upper end with a two-throttle separator located in the housing, which is equipped with a spindle equipped with umya sealing packing and is provided with two fixed conical cavities, which are arranged respectively dividing two throttling cone rigidly interconnected and provided with an adjusting flywheel, arranged in the sealing cap and the lower end of the column is provided with a perforated hollow rod sleeve.
