Abstract: Устройство для спуска кабеля в скважину применяется для проведения работ по исследованию нефтяных скважин с высоким устьевым давлением. Устройство выполнено в форме объемного гидропривода, включающего гидравлический источник энергии, распределительное и запорно-дроссельное устройства и выходную приводную часть (гидродвигатель). Гидравлический источник энергии выполнен в виде двух дифференциальных гидроцилиндров с неодинаковым по величине отношением площадей большей по размеру ступени ступенчатого поршня и меньшей. Оба поршня гидродвигателя, между которыми находится тяговая разрезная втулка для проталкивания кабеля через сальник лубрикатора, снабжены полыми штоками, направленными в противоположные стороны, уплотненными вместе с поршнями в герметичном цилиндрическом корпусе с образованием в нем рабочих полостей. Поршни взаимодействуют с тяговой разрезной втулкой, установленной в корпусе с возможностью совместного возвратно-поступательного движения. Рабочая полость первого из дифференциальных гидроцилиндров, имеющего меньшее по величине отношение площадей ступеней его ступенчатого поршня, расположенная со стороны большей по величине ступени его поршня, соединена каналом (трубопроводом) с полостью высокого давления в устье скважины. Аналогичная же рабочая полость второго из дифференциальных гидроцилиндров соединена каналом через распределительное устройство с той же полостью высокого давления устья скважины и со сливом в окружающую среду. Рабочая же полость, расположенная со стороны меньшей по площади ступени ступенчатого поршня упомянутого первого дифференциального гидроцилиндра, соединена каналом с рабочей полостью гидродвигателя, расположенной со стороны места подстыковки устройства к устью скважины. Аналогичная рабочая полость второго дифференциального гидроцилиндра соединена каналом с рабочей полостью гидродвигателя, расположенной со стороны места подстыковки устройства к лубрикатору. За счет подачи большего по величине давления масла, чем давление рабочей среды (воды) в устье скважины, в рабочие подпоршневые полости гидродвигателя обеспечивается любое необходимое осевое сжатие тяговой разрезной резиновой втулки, расположенной между этими поршнями в замкнутом объеме, т.е. надежное сцепление этой мягкой втулки с кабелем. При этом благодаря подаче разного по величине давления этого масла, поступающего из двух разных дифференциальных гидроцилиндров, обеспечивается в работе шаговое перемещение кабеля за счет совместного циклического движения обоих поршней гидродвигателя вместе с зажатой между ними тяговой разрезной втулкой вниз в скважину и последующего возвращения из скважины вверх уже с незажатой этой втулкой. Использование изобретения повышает надежность благодаря уменьшению износа кабеля и снижает трудоемкость геофизических работ благодаря механизированному приводу с использованием для него практически бесплатной энергии рабочей среды (воды), отбираемой из устья скважины. 3 з.п.ф-лы, 4 ил.

Abstract: FIELD: methods and devices for separation of gas flows. SUBSTANCE: flow of hydrocarbon gas containing components C1, C2 and C3 is separated into volatile fraction including main part of C1 and C2, and into heavier hydrocarbon components containing the main part of propane and propylene. Flow is cooled and/or expanded to partial condensation, and then separated with obtaining of the first flow of vapor which is directed into contacting device (absorber), where the third flow of vapor and flow of fluid containing C3 are separated. Fluid flow containing C3 is directed to distillation column, where the second flow of vapor is separated which contains the main part of components C3 and more heavy hydrocarbon components. Then, the second flow of vapor is subjected to heat exchange with the third flow of vapor for cooling of the second flow of vapor and condensation of at least its part to form condensed flow. At least one part of condensed flow is directed to contacting device (absorber) for close contact with the first flow of vapor. Remained part of condensed flow is supplied to distillation column upper part as raw material. Amount of raw material and temperature of flows in contacting device and distillation column ensure maintenance of temperatures at top of contacting device and distillation column at level of temperatures required for extraction of the main part of final products. Device for separation of gas containing components C1-C3 and more heavy hydrocarbons includes one or several means for heat exchange and/or for expansion of gas to produce condensed gas flow; distillation column for obtaining flow of fluid containing hydrocarbons C3 and flow of vapor containing mainly C1 and C2. Heat-exchange means is connected with distillation column which is also connected with the help of line of the first flow of vapor with contacting device in which the third flow of vapor and flow of fluid containing C3 are formed. Control means is designed for regulation of raw material amount and values of temperature in contacting device and separating column. As a result, components C3 are extracted in amount of more than 93% and full withdrawal of components C2 into residual gas flow is ensured. EFFECT: higher efficiency. 10 cl, 6 dwg, 6 tbl
