Abstract
Изобретение относитс к нефт ной промышленности, в частности к добыче нефти, и предназначено дл глубинно-насосной эксплуатации скважины. Цель - ликвидаци прихвата колонны насосно-компрессорных труб за счет предотвращени осаждени песка в затрубном пространстве над пакером при одновременном обеспечении эффективной промывки песчаных пробок в фильтровой зоне скважины. Затрубное пространство разобщают и периодически заполн ют его промывочной жидкостью. Последнюю подают на забой через сопло. После подачи промывочной жидкости на забой периодически перекрывают сопло путем установки в нем обратного клапана. 1 ил.The invention relates to the oil industry, in particular to the extraction of oil, and is intended for downhole pumping of a well. The goal is to eliminate the sticking of the tubing string by preventing the sand from settling in the annulus above the packer while ensuring effective washing of the sand plugs in the filter zone of the well. The annulus is separated and periodically filled with washing liquid. The latter is fed to the bottom through a nozzle. After the supply of flushing liquid to the bottom, periodically shut off the nozzle by installing a check valve in it. 1 il.
Description
Изобретение относитс к нефт ной промышленности, в частности к добыче нефти, предназначено дл глубинно- насосной эксплуатации скважины и вл етс усовершенствованием изобретени по авт. св. М° 853091.The invention relates to the oil industry, in particular to the extraction of oil, is intended for deep-well operation of the well and is an improvement of the invention according to the author. St. M ° 853091.
Целью изобретени вл етс ликвидаци прихвата колонны насосно-компрессорных труб (НКТ) за счет предотвращени осаждени песка в затрубном пространстве над пакером при одновременном обеспечении эффективной промывки песчаных пробок в фильтровой зоне скважины.The aim of the invention is to eliminate the sticking of the tubing string by preventing the sand from settling in the annulus above the packer while simultaneously ensuring efficient flushing of sand plugs in the filter zone of the well.
На чертеже изображена схема дл реализации способа.The drawing shows a diagram for implementing the method.
Сущность способа эксплуатации -скважины путем подъема скважиннойThe essence of the method of operation of the well by lifting the well
жидкости штанговым насосом 1 заключаетс в том, что затрубное пространство 2 разобщают и периодически заполн ют его промывочной жидкостью, которую подают на забой через сопло 3, причем после подачи промывочной жидкости на забой периодически перекрывают сопло путем установки в нем обратного клапана 4.liquids by the sucker-rod pump 1 consist in that the annulus 2 is separated and periodically filled with washing liquid, which is supplied to the bottomhole through the nozzle 3, and after supplying the washing liquid to the face, the nozzle is periodically closed by installing a check valve 4 in it.
Способ реализуетс следующим образом.The method is implemented as follows.
В скважину спускают разобщитель 5 с соплом 3, снабженным обратным клапаном 4, пакер 6, скважинный насос 1 на колонне НКТ 7. При эксплуатации скважины по мере осаждени песка в фильтровой зоне снижаетс дебит жидкости . Через вентиль 8 в затрубноеA disconnector 5 with a nozzle 3, fitted with a check valve 4, a packer 6, a well pump 1 on the tubing string 7 is lowered into the well. During the operation of the well, the flow rate of the liquid decreases as sand is deposited in the filter zone. Through valve 8 into the annular

пространство 2 подаетс промывочна Жидкость. Под действием гидростати- iiecKoro напора столба промывочной жидкости открываетс обратный клапан Л и осуществл етс промывка песчаной фробки из фильтровой зоны и вынос йеска с откачиваемой жидкостью через ||санал 9 разобщител 5 на прием на- ioca 5. После завершени процесса Лромывки обратный клапан k закрываетс , тем самым предотвращает пос- упление жидкости и песка в затрубное г)ространство 2 над пакером 6,space 2 is supplied with washing liquid. Under the action of the hydrostatic pressure head of the washing liquid column, the check valve L is opened and the sand blasting unit is washed out of the filter zone and the flow of the pumped liquid is carried out through the discharge valve 5 to ioca 5. After the end of the Lromyvki process, the check valve k is closed thereby prevents the liquid and sand from entering the annulus d) spacing 2 above the packer 6,
