Abstract

Изобретение относится к нефтедобывающей промышленности и может быть использовано для добычи нефти посредством установок электроцентробежных насосов из глубоких и сверхглубоких скважин с глубиной до 3 тыс. метров по вертикали и большим газосодержанием (до 250-500 м/м) Для предотвращения перегрева токоввода погружного электродвигателя от теплового потока, идущего по питающему электрическому кабелю, проходящему вдоль корпуса насоса, который перегревается при перекачке электроцентробежным насосом сильно газированных жидкостей, увеличения межремонтного периода эксплуатации установки электроцентробежного насоса, повышения эффективности функционирования установки электроцентробежного насоса и сокращения потери добычи нефти при её добыче из глубоких и сверхглубоких скважин установка электроцентробежного насоса для нефтяной скважины, содержащая сопряженные друг с другом электроцентробежный насос и погружной электродвигатель с прилегающим к корпусу насоса электрическим кабелем, содержит средство тепловой защиты погружного электродвигателя, выполненное в виде расположенных между корпусом насоса и электрическим кабелем опор, изготовленных с возможностью фиксации положения электрического кабеля относительно корпуса насоса с зазором между корпусом насоса и электрическим кабелем и с обеспечением возможности циркуляции скважинной жидкости в зазоре между корпусом насоса и электрическим кабелем и с малой площадью соприкосновения опор с корпусом насоса.The invention relates to the oil industry and can be used for oil production through installations of electric centrifugal pumps from deep and ultra-deep wells with a depth of up to 3 thousand meters vertically and high gas content (up to 250-500 m / m) to prevent overheating of the submersible electric motor from the thermal the flow through the power supply cable running along the pump casing, which overheats when pumping highly aerated liquids with an electric centrifugal pump, increases the overhaul period of operation of an electrical centrifugal pump unit, increase the efficiency of the electrical centrifugal pump unit and reduce the loss of oil production when it is extracted from deep and super-deep wells; , contains a means of thermal protection submersible motor, made in the form of Supported between the pump casing and the electric cable, made with the possibility of fixing the position of the electric cable relative to the pump casing with a gap between the pump casing and the electric cable and allowing the well fluid to circulate in the gap between the pump casing and the electric cable and with a small area of contact between the supports and the casing the pump.
