Abstract
Изобретение относитс к добыче нефти, газа и газоконденсата и м. б. использовано при эксплуатации скважин, наход щихс как в промышленной разработке, так и в поисково-разведочном бурении. Цель изобретени - повышение эффективности борьбы со скважинными отложени ми в вире гидратных пробок. Дл этого закачивают подогретый рабочий агент в колонку труб 1 Слоа:кины 2 дл организации удалени отло- -енмй в заколонном надпакерном пространстве 3 при периодическом изменении давлени в колонне труб 1 от минимальной рабочей депрессии до величины пластового давлени . Подачу подогретого рабочего агента осуществл ют периодически дополнительно в подпакерную зону 4 с дросселиро- ванием этого потока в зэколонное надпакерное пространство 3, причем отбираемую продукцию скважины 2 дросселируют на ее устье. Рабочий агент, поступа в подпэкерную зону 4, дросселируетс через отверстие 10 в пакере 5 и способствует удалению гмдратных лробок в заколонном пространстве 3. Воздействие рабочего агента осуществл етс циклически с частотой циклов ,02 t, где t -суммарное врем работы скважины в сутки, 0,02 - коэффициент размерности. 1 ил., 3 табл. СО сThis invention relates to the extraction of oil, gas and gas condensate, and b. used in the operation of wells that are both in industrial development and in exploration drilling. The purpose of the invention is to increase the effectiveness of the control of well deposits in the hydrate plug trap. For this, a heated working agent is pumped into the column of the 1-Layer: kin 2 pipelines to arrange for the removal of de-envelopes in the annular nadpaknernom space 3 with periodic changes in pressure in the string of pipes 1 from the minimum operating depression to the formation pressure. The supply of the preheated working agent is carried out periodically additionally to the sub-packer zone 4 with throttling of this flow into the zekolonnaya suprapacker space 3, and the selected production of well 2 is throttled at its mouth. The working agent, entering the sub-beaker zone 4, is throttled through the opening 10 in the packer 5 and contributes to the removal of the microblock in the annulus 3. The impact of the working agent occurs cyclically with a frequency of cycles 02 t, where t is the total time of the well operation per day, 0 , 02 - dimensionality factor. 1 dw., 3 tab. SO with
