Granted: 2002-11-27
Abstract: FIELD: rubber industry. SUBSTANCE: invention relates to production of polyisoprene rubber from isopentane accomplished in at least one preponderant isopentane- dehydrogenation zone and one preponderant resulting isoamylene-dehydrogenation zone, wherein dehydrogenation is effected on different catalysts and/or at different temperatures and pressures. Crude product is isolated in isolation zone, after which mixture of C5- hydrocarbons is subjected to rectification separation to yield isoprene fraction, which is further purified to remove polymerizationinhibiting impurities and transferred into isoprene-polymerization zone. According to invention, above-mentioned C5- hydrocarbon mixture mainly containing pentadienes, isoamylenes and optionally isopentane is separated from at least piperylenes and then freed from at least cyclopentadiene, alpha- acetylenes, and oxygen-containing compounds. Polymer(s) is treated to separate at least C5 hydrocarbons recycled into dehydrogenation zone(s) and/or into rectification zone(s), and/or partly into polymerization zone.

Abstract: Изобретение относится к нефтедобывающей промышленности, в частности к добыче нефти из обводняющихся скважин. Обеспечивает рентабельную добычу нефти. Сущность изобретения: в способе добычи нефти из обводняющихся скважин поднимают газожидкостную смесь глубинным насосом. Согласно изобретению с увеличением содержания воды в добываемой скважинной продукции изменяют режим притока и подъема добываемой скважинной продукции, исходя из учета месторасположения скважины на структуре нефтеносной залежи, геолого-физических условий строения нефтяного пласта и характеристик насыщающих его жидкостей. Изменяют величину депрессии на нефтяной пласт с большей на меньшую, одновременно уменьшают глубину спуска и производительности глубинного насоса. Обеспечивают меньшую скорость подъема пластовой воды по сравнению со скоростью всплытия в ней нефти. Увеличивают фронт вытеснения нефти и повышения давления в нефтяном пласте. По способу добычи нефти из обводняющихся скважин, когда нефтеносный пласт обводнен, но еще в нем имеются целики остаточной нефти, а при разработке пластовая продукция непрерывно движется, вода занимает нижние части пласта, а нефть занимает верхние зоны структурных поднятий. Согласно изобретению при поддержании в призабойной зоне скважины депрессии, не нарушающей процесс перераспределения отдельных компонентов добываемой скважинной продукции, способствующей накоплению нефти в сводовой части структур и макроструктур, под действием этой депрессии поддерживают движение нефти по нефтяному пласту и приток к эксплуатационной скважине. Нефть в стволе скважины всплывает через толщу воды, установленной в стволе скважины на определенной высоте, исходя из условий сохранения оптимального режима. Предварительно подают в призабойную зону деэмульгатор-растворитель. При этом обеспечивают непрерывное всплытие нефти через толщу воды, отделение нефти от остаточной воды в нефтеводоотделителе, накопление нефти в камере-накопителе. Откачивают ее из камеры-накопителя. Отделившуюся воду направляют к забою скважины вместе с подаваемым в воду деэмульгатором. Избыток воды выбрасывают через обратный клапан в водоносную часть нефтяного пласта. Устройство включает камеру-накопитель, представляющую собой кольцевое пространство, образованное между колонной насосно-компрессорных труб малого и большего диаметров. Трубы большего диаметра образуют корпус камеры-накопителя, подвешенного выше к колонне насосно-компрессорных труб большего диаметра, чем насосно-компрессорные трубы, спущенные внутри камеры-накопителя с глубинным насосом определенного диаметра на штангах. Ниже камеры-накопителя спущен изолированный от камеры-накопителя нефтеводоотделитель, в средней части которого установлен уплотнитель-разделитель, при помощи которого нижняя зона скважины разделена от ее верхней зоны. Ниже уплотнителя-разделителя расположены отверстия для поступления добываемой скважинной продукции. 3 с. и 1 з.п. ф-лы, 3 ил.
