Description
(54) УСТРОЙСТВО ДЛЯ ПОДАЧИ РЕАГЕНТА И ВОДЫ НА ЗАБОЙ СКВАЖИНЫ(54) DEVICE FOR FEEDING REAGENT AND WATER ON WELL HOLE
Изобретение относитс к области нефтедобывающей промышленности, в частности к способам подачи реагента и воды на забой скважины, например при внутрискважинной подготовке нефти.The invention relates to the field of the oil industry, in particular to methods for supplying reagent and water to the bottom of a well, for example, in the downhole preparation of oil.
Известны способы, системы и устройства дл проведени промысловой доэмульсации и обессоливани нефти путем перемешивани продукции скважины с водой и деэмульгатором в сборных трубопроводах и аппаратах 1. Однако этот способ не обеспечивает качественной доставки реагента.Methods, systems and devices are known for carrying out field pre-emulsification and desalting of oil by mixing well products with water and a demulsifier in prefabricated pipelines and devices 1. However, this method does not provide high-quality delivery of the reagent.
Наиболее близким по технической сущности и достигаемому результату вл етс устройство дл подачи реагента на забой скважины с помощью забойного дозатора ДРШ. Устройство состоит из колонны подъемных труб, спущенных в скважину. Ни же башмака колонны (при фонтанном и компрессорном способах эксплуатации) или приема насоса (при глубиннонасосном способе ) крепитс забойный дозатор гравитационного типа.The closest in technical essence and the achieved result is a device for supplying a reagent to the bottom of a well with the help of a bottomhole dispenser DRSh. The device consists of a column of lifting pipes, lowered into the well. Under the column shoe (with the fountain and compressor modes of operation) or pump intake (with the deep pump method), a downhole gravity-type metering device is attached.
Однако указанное устройство обеспечивает подачу в скважину лишь определенного количества реагента, завис щего от объема контейнера дозатора (емкости дл However, this device provides only a certain amount of reagent to the well, depending on the volume of the dispenser container (tank for
реагента), после чего дозатор поднимают на поверхность дл перезаправки. Эта операци трудоемка, так как необходимо поднимать на поверхность всю колонну труб, на врем перезаправки эксплуатацию скважины прекращают.reagent), after which the dispenser is raised to the surface for refilling. This operation is time consuming, since it is necessary to lift the entire pipe string to the surface, the well operation is stopped for the time of refilling.
Целью изобретени вл етс повышение эффективности его работы путем сокращени спуско-подъемных операций.The aim of the invention is to increase the efficiency of its work by reducing the tripping.
Цель достигаетс тем, что устройство снабжено гибким шлангом с запорным устройством , который соедин ет устье скважины с емкостью и дозатором, а также тем, что на гибком шланге ниже запорного устройства установлен обратный клапан.The goal is achieved by the fact that the device is equipped with a flexible hose with a locking device that connects the wellhead to the tank and the metering device, as well as the fact that a non-return valve is installed on the flexible hose below the locking device.
На чертеже изображена схема устройства дл подачи реагента и воды на забойThe drawing shows a diagram of a device for supplying reagent and water to the bottom

Глубинный насос I подвешен на колонне подъемных труб 2 и с помощью насосных штанг 3 соединен со станком-качалкой 4.Depth pump I is suspended on a column of lifting pipes 2 and using pump rods 3 is connected with a pumping unit 4.
Ниже приемного клапана глубинного насоса размещен впускной патрубок 5 с окнами дл поступлени продукции скважины. К нижней части патрубка 5 присоединены дозатор 6 и емкость дл реагента ( оды) 7.Below the inlet valve of the submersible pump is an inlet 5 with openings for the production of a well. A dispenser 6 and a reagent container (odes) 7 are attached to the lower part of the pipe 5.
